[Entomology • 2017] Taxonomic Review of the Oriental Flower Beetle Coilodera penicillata species complex (Coleoptera: Scarabaeidae: Cetoniinae)


Coilodera grandimaculata   Qiu, Xu & Chen, 2017


Abstract

The taxonomy of the Coilodera penicillata Hope, 1831 (Coleoptera: Scarabaeidae: Cetoniinae) species complex, which is recognized by the black body and elytra with larger tomentose maculae, is revised. Six Indochinese species assigned to this complex, including Coilodera grandimaculata new species from Tibet, China. Coilodera nigroscutellaris Moser, 1902 revised status and C. formosana Moser, 1910 revised status formerly treated as two subspecies of C. penicillata Hope, 1831 are elevated to species rank. The distribution of C. penicillata in China is confirmed based on examination of specimens from Yunnan and Tibet, and almost all previous Chinese literature records should be referred to C. nigroscutellaris. Coilodera dives (Gory & Percheron, 1833) revised status previously synonymized with C. penicillata is herein considered as a valid species based on the examination of types and additional specimens, and C. miksici Antoine, 1986 new synonymy is regarded as a junior synonym of C. dives. A lectotype is designated for Coilodera dives (Gory & Percheron, 1833). The record of C. mearesii (Westwood, 1842) in southeastern China is attributed to a misidentification of C. nigroscutellaris, and it is here newly recoreded from Tibet near the Nepal-China border. Diagnosis characters and intraspecific variations are illustrated for all six species, new distribution records and a key to species are also presented. Ecological information is provided for all species.

[Botany • 2017] Dendrobium bannaense • A New Species (Orchidaceae; Epidendroideae) from Yunnan, China: Molecular and Morphological Evidence


 Dendrobium bannaense
Tian, Li, Yang & Huang, 2017


Abstract

A new species, Dendrobium bannaense, is described from Yunnan, China, based on the molecular and morphological evidence. It belongs to section Dendrobium according to analysis of combined nrITS and plastid datasets (matK, rbcL, trnH-psbA, and trnL intron). Morphological analysis reveals that D. bannaense is similar to D. parishii, but differs in having a white lip with purplish stripes and without a deep purple blotch on either side; the disk is with 3 longitudinal ridges, extending from base to upper-middle part, and lower-middle part is thickened and swell as callus shape at the joint of lip and claw.

Abstract 
A new species of worm-like lizard, Dibamus floweri, is described from Fraser’s Hill, Pahang, in the central highlands of Peninsular Malaysia based on the following unique combination of characters: maximum SVL of 112 mm; tail length 11.4–15.2% of SVL; labial and nasal sutures absent; rostral suture present but incomplete; a single postocular; four scales bordering the posterior edge of first infralabial; no enlarged, medial, sublabial scale; 21 scale rows around midbody; 23 scale rows around the body immediately posterior to head; 21 scale rows around the body immediately anterior to vent; 175–194 ventral scales; 23–46 subcaudal scales and light coloured bands on body. Dibamus floweri, new species, is the third species of dibamid discovered in Peninsular Malaysia and is the first montane species. Its discovery underscores the importance of uplands regions as important habitats for herpetological diversity and their understudied nature.

Dibamus floweri, new species
Flower’s blind lizard

Diagnosis. Dibamus floweri, new species, differentiated from all other congeners by this combination of characters: maximum SVL of 112 mm; tail length 11.4–15.2% of SVL; labial, nasal sutures absent; rostral suture present but incomplete; single postocular; four scales bordering posterior edge of first infralabial; no enlarged, medial, sublabial scale; 21 midbody scale rows; 23 transverse scale rows just posterior to head; 21 transverse scale rows just anterior to vent; 175–194 ventral scales; 23–46 subcaudal scales; relative size of frontal to frontanasal 1.1–1.5; relative size of interparietal to surrounding scales 1.3–1.8; and light coloured bands on the body. These characters are scored across all nominal species of Dibamus in Table 2.

Etymology: The specific epithet, floweri, is in honour of Major Stanley Smyth Flower, who was one of the pioneers for herpetological discoveries in the Malay Peninsula. He made many notable discoveries over the course of his explorations in the region and his natural history observations well over a century ago were very detailed and contributed tremendously to improving our understanding of the ecology and behaviour of many species to this day.

 Distribution: Dibamus floweri, new species, is presently known only from Fraser’s Hill, Pahang, Peninsular Malaysia at elevations between 1,207 and 1,500 m (Fig. 3).

(F) Leaf litter microhabitat at Fraser’s Hill, Pahang where the paratype of Dibamus floweri, new species, was found.

Natural history: Both specimens were found while digging through leaf litter that had accumulated along the banks of roads. The holotype was discovered at night in a drainage ditch along Jalan Girdle in a damp and shaded area. The paratype was uncovered during the day underneath approximately 3 cm beneath the soil (Fig. 2F), and in the same pile of leaf-litter, the skink, Larutia miodactyla (Boulenger, 1903) was also found. When handled, both specimens flared up their body scales, giving them a wrinkled appearance (Fig. 1C). This behaviour is interpreted as a defensive, anti-predator mechanism employed by Dibamus to mimic a possible non-palatable species of worm (Darevsky, 1992). The other two Peninsular Malaysian species, D. booliati and D. tiomanensis display the same behaviour when agitated (Das & Yaakob, 2003; Diaz et al., 2004; Grismer, 2011).

[Paleontology • 2017] Spinosaur Taxonomy and Evolution of Craniodental Features: Evidence from Brazil


Spinosaurid cranial remains from Brazil.
Sales & Schultz, 2017 

Abstract

Fossil sites from Brazil have yielded specimens of spinosaurid theropods, among which the most informative include the cranial remains of IrritatorAngaturama, and Oxalaia. In this work some of their craniodental features are reinterpreted, providing new data for taxonomic and evolutionary issues concerning this particular clade of dinosaurs. The mesial-most tooth of the left maxilla of the holotype of Irritator is regarded as representing the third tooth position, which is also preserved in the holotype of Angaturama. Thus, both specimens cannot belong to the same individual, contrary to previous assumptions, although they could have been the same taxon. In addition, the position of the external nares of Irritator is more comparable to those of Baryonyx and Suchomimus instead of other spinosaurine spinosaurids. In fact, with regards to some craniodental features, Brazilian taxa represent intermediate conditions between Baryonychinae and Spinosaurinae. Such a scenario is corroborated by our cladistic results, which also leave open the possibility of the former subfamily being non-monophyletic. Furthermore, the differences between spinosaurids regarding the position and size of the external nares might be related to distinct feeding habits and degrees of reliance on olfaction. Other issues concerning the evolution and taxonomy of Spinosauridae require descriptions of additional material for their clarification.

Final remarks
Spinosaurid dinosaurs have been surrounded by an enigmatic atmosphere due to their bizarre anatomy and morphology as well as the fragmentary nature of most collected specimens. The tragic loss of the holotype of Spinosaurus aegyptiacus also contributed to this condition. Despite being incomplete, spinosaurid cranial remains from Brazil are informative in multiple ways and help fill in some gaps in the knowledge on these theropods. The reinterpretation of certain craniodental features supports, for example, the distinction between Irritator and Angaturama at least at the individual level, and our cladistic results indicate the latter taxon and Oxalaia as successive outgroups of MSNM V4047. In addition, the evolution of spinosaurid craniodental features is likely related to different trends towards semiaquatic and/or piscivorous habits. These trends might have had a major impact on the position and size of the external nares, suggesting the reduction of the importance of olfaction in relation to other senses during foraging. However, other issues remain more disputable, such as the possible non-monophyly of Baryonychinae, the possible synonymy between the Araripe spinosaurids, and the sequence of morphological changes during the evolutionary history of Spinosauridae. Further study is needed to address these issues, including the formal description of additional cranial and postcranial remains. In this sense, although African materials are usually the focus of most investigations, Brazilian specimens play an important role in discussions concerning the evolution and paleobiology of Spinosauridae. This statement is clearly corroborated by new findings of these dinosaurs in understudied fossil sites.

[Herpetology • 2017] Strophurus trux • A New Species of Gecko (Squamata: Diplodactylidae: Strophurus) from central Queensland, Australia


 Strophurus trux  Vanderduys, 2017

Golden-eyed Gecko  ||  DOI:  10.11646/zootaxa.4347.2.7

Abstract

A new species of diplodactylid gecko in the genus Strophurus Fitzinger, from central Queensland, Australia, is described herein as Strophurus trux sp. nov. It is similar to the recently described Strophurus congoo Vanderduys from north Queensland and apparently shares a habitat preference for Triodia hummock open woodlands. It is notably different from the latter in possessing a vivid yellow to golden eye. It is only known from one small area of the Brigalow Belt Bioregion, although it is expected to occur more widely than the one area in which it has been found. It is likely that it is endemic to the Brigalow Belt Bioregion.

Keywords: Reptilia, Brigalow Belt, Triodia, Golden-eyed Gecko



Strophurus trux sp. nov.
Golden-eyed Gecko

Etymology. The specific epithet " trux " is Latin for wild, savage, harsh and pitiless, including instruments of human savagery, and also of the scene of such cruelty (Lewis & Short 1879; Glare 1982). This name was Chosen in reference to the only location known for Strophurus trux sp. nov. It is in the proximity of the "Marlborough stretch", a section of the old Bruce Highway in Central Queensland with notoriety as a wild and dangerous place in the 1960s and 1970s because of a series of murders and shootings (Gibson 2002) and its general remoteness.

Abstract
An allopatric population of big-eared climbing rats (Ototylomys) from the Northern Highlands of Chiapas, Mexico, is described as a new species. The new taxon is part of a unique montane rainforest community that includes several other endemic species in the limited geographic range between the Río Grijalva and the Central Depression of Chiapas. Several cranial, external, and molecular characters distinguish this new species of big-eared climbing rat from its more widely distributed congener, Ototylomys phyllotis. We performed principal component and discriminate function analyses of cranial measurements, and found that specimens of the new species consistently could be distinguished from other Ototylomys with strong statistical support. Compared with exemplars of Ototylomys from elsewhere in their range, the new species possesses a karyotype that differs by 3 additional biarmed chromosome pairs, is fixed or nearly fixed for distinct electromorphs at 12 allozyme loci, and the mean genetic distance exceeds 14%, based on comparisons of the mitochondrial cytochrome b gene between the new species of Ototylomys and representatives of O. phyllotis. The restricted distribution in montane karst rainforest suggests that the species and its habitat may be a matter of conservation concern.

Una población alopátrica de rata orejuda trepadora (Ototylomys) de las Tierras Altas del Norte de Chiapas, México se describe como una nueva especie. El nuevo taxón es parte de una comunidad única de bosque lluvioso montano que incluye varias especies endémicas en el área de distribución geográfica limitada entre el Río Grijalva y la Depresión Central de Chiapas. Varios caracteres craneales, externos, y moleculares distinguen la nueva rata orejuda trepadora de su congénere más ampliamente distribuido, Ototylomys phyllotis. Se realizaron análisis de componentes principales y de función discriminante de los caracteres craneales, y se encontró que los especímenes de La Pera fueron consistentemente distinguidos de otros Ototylomys con un fuerte soporte estadístico. En comparación con ejemplares de Ototylomys del rango, la nueva especie posee un cariotipo que difiere por 3 pares adicionales de cromosomas biarmados, está fijo o casi fijo por distintos electromorfos en 12 loci alozímicos. Adicionalmente, la media de la distancia genética comparada del gen mitochondrial citocromo b entre la nueva especie de Ototylomys y representantes de O. phyllotis, excede el 14%. La distribución restringida en el bosque lluvioso montano kárstico sugiere que la especie y su hábitat pueden ser de importancia para la conservación.

ABSTRACT 

The genus Middletonia in Thailand is revised. We recognise four species, including the newly described Middletonia glebosa C.Puglisi and the resurrected M. reticulata (Barnett) C.Puglisi. A key to the species, full descriptions and proposed conservation assessments are provided. 

KEYWORDS: taxonomy, new species, Flora of Thailand

Photographs by Preecha Karaket (A, C–E) and David Middleton (B).


MIDDLETONIA C.Puglisi, 
Taxon. 65: 286. 2016. 
Type species: Middletonia multiflora (R.Br.) C.Puglisi.

Five species, found in India, Bangladesh, Bhutan, Myanmar, China, Thailand, Laos, Cambodia, Vietnam and Malaysia. Four in Thailand.


1. Middletonia evrardii (Pellegr.) C.Puglisi, Taxon. 65: 286. 2016

Distribution.— Lao PDR, Vietnam.
Thailand.— EASTERN: Nakhon Ratchasima, CENTRAL: Nakhon Nayok
 Ecology.— Evergreen forest.

Note.— The material from Thailand differs slightly from the Vietnamese material, especially in the leaf shape which is more elongated and with an acute apex in the Thai specimens. As there are rather few specimens from throughout the distribution range, with no floral material from Thailand available for dissection, further collections are necessary to assess whether the Thai and Vietnamese plants belong to one or more species.

2. Middletonia glebosa C.Puglisi, sp. nov. 

Similar to Middletonia regularis in having the inflorescences shorter than the leaves and to Middletonia reticulata in the shortly caulescent habit. Differs from both in having a dense indumentum on the adaxial side of the leaf, with glands and eglandular hispid hairs (upperleafsurface glabrescent or minutely glandular in Middletonia regularis, glabrescent in M. reticulata), and in the short, non-twisted, lumpy and irregular fruit (longer, weakly to strongly twisted, smooth and regular in M. regularis and M. reticulata). 

Type: Thailand, Sukhothai, Ram Kham Haeng National Park, Khao Luang, alt. 520 m, 11 Oct. 2012, fr., Middleton, Karaket, Suddee & Triboun 5559 (holotype E [E00547434]; isotypes BK, BKF [SN201922]).  

Distribution.— Cambodia.
Thailand.— NORTHERN: Sukhothai. 
 Ecology.— Mixed deciduous forest with bamboo on granite bedrock.

Etymology.— The specific epithet is the Latin adjective glebosus, -a, -um, which means “lumpy” and refers to the peculiar surface of the capsule.

Notes.— In Ram Kham Haeng National Park this species grows in a mixed population with Middletonia reticulata. The two are readily told apart in the field by Middletonia glebosa having softer, paler leaves, a shorter inflorescence, generally slightly smaller flowers, and the curious short, straight, lumpy fruit. The species is known only from Ram Kham Haeng National Park and a single collection made around 150 years ago in Cambodia. The Cambodian collection, placed in Paraboea regularis by Xu et al. (2008), is only in fruit so the identification will need to be verified with flowering material. However, the fruit of this species is rather distinctive.


3. Middletonia regularis (Ridl.) C.Puglisi, Taxon. 65: 287. 2016.

Distribution.— Malaysia. 
Thailand.— PENINSULA: Surat Thani, Phangnga; SOUTH-WESTERN: Kanchanaburi.

Ecology.— Lowland evergreen forest on limestone soils. 

Note.— The protologue of Paraboea monticola suggests the flowers to be much larger: “lobes … 6–9 × c. 6.5 mm”. However, none of the material available for this study had lobes longer than 3.3 mm. 

4. Middletonia reticulata (Barnett) C.Puglisi, comb. nov.
Boea reticulata Barnett, Nat. Hist. Bull. Siam Soc. 20: 20. 1961.
Type: Thailand, Chiang Mai, Mae Wang

Ecology.— Mixed deciduous forest on granite bedrock. 

Distribution.— Currently endemic to Thailand but possibly also occurring in Lao PDR and Myanmar.
Thailand.— NORTHERN: Mae Hong Son; Chiang Mai; Lamphun; Lampang; Phrae; Sukhothai. 

 Note.— This species is resurrected from synonymy of Middletonia multiflora (R.Br.) C.Puglisi from which it differs in the distinctively reticulate venation pattern covered in loose brown indumentum on the lower surface of the leaves, and in the auriculate leaf base. Middletonia multiflora has a denser indumentum on the leaf and the tertiary venation is less densely reticulate and less visible altogether. Middletonia multiflora is widespread along the northern distribution of the genus (from India to Vietnam), but none of the material from Thailand studied can be attributed to M. multiflora.

[Botany • 2017] Magnolia montebelloensis • A New Species in Section Magnolia from Lagunas de Montebello National Park, Chiapas, México, with A Key to Magnoliaceae of Chiapas


Magnolia montebelloensis   A.Vázquez & Pérez-Farr.

 Vázquez-García, Pérez-Farrera, Gómez-Domínguez, Muñiz-Castro & Sahagún-Godínez, 2017

Abstract

A new species of Magnolia, from the Lagunas de Montebello National Park, in the central highlands of Chiapas, Mexico, is described and illustrated. Magnolia montebelloensis belongs to section Magnolia; it differs from M. poasana in its smaller habit, densely pubescent terminal twig internodes, stipules and spathaceous bracts, shorter peduncular internodes and more numerous stamens. A key, an ecological and a conservation assessment of the eight Chiapan species of Magnoliaceae are included. Magnolia montebelloensis grows in montane rain forest and is contrasted with other Chiapan Magnolia species regarding their climate and vegetation preferences. It was assessed as critically endangered (CR) according to IUCN B1ab(ii,iii) and B2ab(iii) criteria. Half of Magnolia species in Chiapas occur in protected natural areas, and thus immediate action is required to protect the other four species, M. faustinomirandae, M. mayae, M. sharpii and M. zamudioi. Seven out of the eight Magnolia species (88%) are not found in ex-situ collections despite being endangered or critically endangered.

[Entomology • 2017] Taxonomic and Biogeographic Revision of the New Guinean genus Ophiotettix Walker, 1871 (Tetrigidae: Metrodorinae: Ophiotettigini trib. nov.), with the Descriptions of 33 New Species


Ophiotettix storozhenkoiO. filiformaO. pulcherrima, et al

Tumbrinck & Skejo, 2017

Long-headed pygmy grasshoppers (genus Ophiotettix Walker, 1871) from the New Guinean region (New Guinea and adjacent islands) are taxonomically and biogeographically reviewed. For Ophiotettix and the morphologically similar genera Paraspartolus Günther, 1939, Spartolus Stål, 1877 and Threciscus Bolívar, 1887 a new tribe is erected, Ophiotettigini trib. nov. This tribe is close to Clinophaestini Storozhenko, 2013, which is placed here also under Metrodorinae. Bufonidinae syn. rev. are regarded to be synonymous with Batrachideinae, not Cladonotinae, as previously considered. Statuses of currently known taxa of Ophiotettix are reviewed. The genus now includes 40 species, seven of them previously described: O. buergersi Bolívar, 1929, O. cygnicollis Walker, 1871, O. limosina (Snellen van Vollenhoven, 1865), O. lorentzi Bolívar, 1929, O. modesta Bolívar, 1929 stat. rev., O. scolopax Bolívar, 1929, O. westwoodi Bolívar, 1929 stat. rev. 33 new species are described and illustrated, namely: O. amberiana sp. nov., O. bewana sp. nov., O. bomberaiensis sp. nov., O. brevicollis sp. nov., O. cheesmanae sp. nov., O. depressa sp. nov., O. filiforma sp. nov., O. flyriveriensis sp. nov., O. fritzpahli sp. nov., O. hansscholteni sp. nov., O. imbiana sp. nov., O. kaitani sp. nov., O. karimuiensis sp. nov., O. katharinae sp. nov., O. luce sp. nov., O. meggy sp. nov., O. mountnokensis sp. nov., O. parvicollis sp. nov., O. projecta sp. nov., O. pulcherrima sp. nov., O. pushkari sp. nov., O. quateorum sp. nov., O. rebrinae sp. nov., O. roesleri sp. nov., O. rohwedderi sp. nov., O. sanguinea sp. nov., O. schapinae sp. nov., O. stallei sp. nov., O. storozhenkoi sp. nov., O. subbrevicollis sp. nov., O. telefominensis sp. nov., O. tenuis sp. nov., and O. toxopei sp. nov. An annotated identification key to species is provided. Antennal morphology (especially morphology of five apical segments) is diagnostically important in the taxonomy of this group and provides the best morphological character for species delimitation. Function of modified antennae is not fully understood. Differences between species exist also in head morphology, facial colouration, and morphometrics. Pygmy Giraffhoppers are a diverse group occupying most biogeographical regions of New Guinea North of the Central range, while only few species inhabit areas south of the central range.

Abstract

The monotypic genus Hindumanes Logunov, 2004 is revised. We present fresh specimens of Hindumanes karnatakaensis (Tikader & Biswas, 1978), the type species, and describe Hindumanes wayanadensis sp. nov. from the Wayanad Wildlife Sanctuary, a part of the Western Ghats, Kerala, India. This paper provides the first description of the male of H. karnatakaensis and a redescription of its female. We also transfer the genus from Asemoneinae Maddison, 2015 to Lyssomaninae Blackwall, 1877. The relationship between Hindumanes and Lyssomanes Hentz, 1845 and the zoogeography of the subfamily are discussed. The distribution records of the genus are mapped.

Abstract

 An exceptional new specimen of the stem-basilisk Geiseltaliellus maarius from the middle Eocene of Messel, Germany, preserves details of the squamation of this extinct species. The dorsum and extremities were covered by small, rhomoidal scales, about 0.2 mm in size in most places; somewhat larger scales were present on the lower extremities and on the head. Scales of the venter were arranged in transverse rows, unlike in extant Polychrus and Laemanctus. There is some evidence that the scales on the extremities possessed keels, as in extant basilisks and Polychrus. Keratin appears to be preserved in places. The “Oberhäutchen” is nearly featureless, probably the result of postmortem microbial decomposition; scale organs were not observed. Overall, the body of G. maarius possessed a fine, homogeneous squamation most similar to Basiliscus. Possible sexual dimorphism in the form of the parietal crest raises the prospect of a projecting median keel composed of skin in male G. maarius, although direct evidence on this point is currently lacking. The squamation of the tail is discussed in light of the pseudoautotomy shown by this species. 

Key words: Fossils, Corytophanidae, Eocene, scales, keratin.

[Herpetology • 2017] Gephyromantis angano • A New Frog Species of the Subgenus Asperomantis (Anura, Mantellidae, Gephyromantis) from the Bealanana District of northern Madagascar

Abstract
A recent study on a group of rough-skinned Gephyromantis frogs from Madagascar (Anura: Mantellidae: Mantellinae) established a new subgenus, Asperomantis, with five described species and one undescribed candidate species. Based on newly collected material from the Bealanana District, we address the taxonomy of this candidate species, and reveal that it consists of two populations with low genetic and morphological divergence but considerable bioacoustic differences that are obvious to the human ear. As a result, we describe some of the specimens formerly assigned to Gephyromantis sp. Ca28 as Gephyromantis angano sp. n. and assign the remaining specimens from a locality between Bealanana and Antsohihy to a new Unconfirmed Candidate Species, G. sp. Ca29. Gephyromantis angano sp. n. is a small species that strongly resembles G. asper and G. ceratophrys, but it differs from these and all other Gephyromantis species by a unique, clinking advertisement call. The new species may be highly threatened by habitat fragmentation, but at present we recommend it be treated as Data Deficient until more data are available to assess its distribution. We discuss the curious relationship between G. angano sp. n. and G. sp. Ca29, which we suspect may represent a case of incipient speciation. We also identify two additional new Unconfirmed Candidate Species of Gephyromantis based on sequence data from other specimens collected during our surveys in the Bealanana District.

Gephyromantis (Asperomantisangano sp. n.
Gephyromantis sp. Ca28 — Perl et al. (2014)

Diagnosis: Gephyromantis species assigned to the subgenus Asperomantis based on the presence of small dermal spines on the elbow and heel, presence of inner and outer dorsal ridges as defined by Vences and Glaw (2001), Type 2 femoral glands sensu Glaw et al. (2000)Glaw et al. (2000), moderately enlarged finger and toe tips, absence of webbing between fingers, moderate webbing between toes, presence of paired blackish sub-gular vocal sacs in males, and a distinct whitish spot in the middle of the tympanic field (Vences et al. 2017). DNA sequence data from a fragment of the 16S gene supports this assignment. Gephyromantis angano sp. n. is characterized by the following suite of morphological characters: (1) adult SVL 29.1–30.5 mm, (2) TD/ED 0.61–0.71, (3) small supraocular spines, (4) large femoral glands consisting of numerous small granules, (5) moderately raised dorsal ridges, (6) granular dorsal skin, (7) relatively short hindlimbs (HIL/SVL 1.73–1.81 in males), and (7) its unique call (see above).

Within the subgenus AsperomantisGephyromantis angano sp. n. can be distinguished from G. ambohitra, G. spinifer, and G. tahotra by its smaller size (male SVL < 30 mm, vs. >31 mm, female SVL up to 30.5 mm vs. >32 mm); from G. spinifer by its less granular dorsal skin and smaller supraocular spines; from G. asper and G. ceratophrys by its generally shorter hindlimbs in males (HIL/SVL 1.73–1.81 vs. 1.77–2.11); and from G. ceratophrys by more granules per femoral gland (26–69 vs. 14–20). Bioacoustically, it is distinguished from all of these species by its call duration (41–98 ms vs. 5–44 ms in G. asper and G. ceratophrys, and 98–274 ms in Gambohitra and Gtahotra), unpulsed calls (vs. pulsed in G. ambohitra and G. tahotra), calls repeated faster than in Gceratophrys, and dominant frequency (3703–3875 Hz vs. 1435–3366 Hz in G. ambohitra, and G. tahotra).

Etymology: Angano is a Malagasy word meaning ‘fable’. The new material for this species was collected on Expedition Angano, a research expedition to the Bealanana District of northern Madagascar to assess the impacts of forest fragmentation on the reptiles and amphibians. The epithet is used as an invariable noun in apposition to the genus name.

Natural history and distribution: One specimen of this species has been collected in Antsahan’i Ledy, and numerous specimens of this species were encountered during fieldwork on the Ampotsidy mountains (Fig. 7). Calling males were generally found in association with slow flowing water, in the case of the holotype at the source of a spring, in close syntopy with Boophis madagascariensis and a Mantidactylus (Brygoomantis) species. Males called up to 1 m above the ground from fern fronds and other low foliage. Females were found both near to and away from water, during the day and at night, but were less commonly encountered. No eggs were observed, but highly ovigerous females were found in January (e.g. Fig. 6e). The call of the species is loud and carries over long distances, so that it can be heard alongside the calls of Boophis madagascariensis from well outside of some small forest fragments in the vicinity of Ampotsidy. In a small forest fragment where vouchers of Gephyromantis (Asperomantis) tahotra were collected (1368 m a.s.l.), G. angano sp. n. could also be heard; this appears to be the first ever record of any two Asperomantis species occurring in close syntopy (Vences et al. 2017).
