[Herpetology • 2017] Rediscovery and Range Extension of the Guinean Skink Trachylepis keroanensis (Chabanaud, 1921) (Squamata: Scincidae)


Trachylepis keroanensis  (Chabanaud, 1921)


  Abstract

 We report the rediscovery of the skink Trachylepis keroanensis (Chabanaud, 1921) 90 years after its description. For the first time pictures of live specimens are shown and the known, now extended, distribution is presented. The clear morphological differences (body shape, colouration and most notably ratio tail length to body length) towards Trachylepis perrotetii (Duméril & Bibron, 1839), which justify the species status, are confirmed.

[Fungi • 2017] Gymnosporangium przewalskii (Pucciniales, Basidiomycota) from China and Its Life Cycle


Gymnosporangium przewalskii  Y. M. Liang & B. Cao


Abstract

In an investigation of rust fungi in Qinghai Province, northwestern China, the novel rust species Gymnosporangium przewalskii was identified based on morphology and phylogenetic analyses. Phylogenetic analyses using the internal transcribed spacers (ITS) and the large subunit (LSU) rRNA partial gene revealed that G. przewalskii is monophyletic and distinct from other Gymnosporangium species. The life cycle of this new taxon was clarified based on molecular data. Its spermogonial and aecial stages occurred on Sorbus koehneana, and its telial stage was found on Juniperus przewalskii.

[Herpetology • 2017] Sphaerotheca pashchima • A New Species of Burrowing Frog (Anura: Dicroglossidae) from western India


Sphaerotheca pashchima
Padhye, Dahanukar, Sulakhe, Dandekar, Limaye & Jamdade, 2017  


Abstract
Sphaerotheca pashchima, a new species of burrowing frog, is described from western India. It can be diagnosed from all its congeners based on a combination of characters including interorbital width less than upper eyelid width, snout to nostril distance less than half of eye diameter, nostril nearer to snout than to eye, internarial distance greater than inter orbital distance, snout rounded, dorsum rough and warty, finger 2 length equal to or less than finger 4 length, finger 1 less finger 3 length, outer metatarsal tubercle absent, tibio tarsal tubercle absent, length of inner metatarsal tubercle more than three times the inner toe length and reduced webbing. We also provide 16S rRNA gene sequence for S. pashchima sp. nov. and show that it is genetically distinct from species of Sphaerotheca for which genetic data is available.

Keywords: Amphibia, molecular phylogeny, taxonomy.

Sphaerotheca pashchima sp. nov.
 Suggested common name: Western Burrowing Frog

Holotype: BNHS 6000, male (41.0mm SUL), 05.vi.2016, India: Maharashtra: Saswad-Waghapur Road, Ambodi Village (18.3500N, 74.0410E, 747m), coll. S. Sulakhe et al.

Diagnosis: Sphaerotheca pashchima sp. nov. differs from all other congeners based on the following combination of characters: interorbital width less than upper eyelid width; snout to nostril distance less than half of eye diameter; nostril nearer to snout than to eye; internarial distance greater than inter orbital distance; snout rounded; dorsum rough and warty; finger 2 length equal to or less than finger 4 length; finger 1 less finger 3 length; outer metatarsal tubercle absent; tibio tarsal tubercle absent; length of inner metatarsal tubercle more than three times the inner toe length; and webbing formula I1--2-II1-3-III2-3½IV3½-2+V.

Etymology: Pashchim’ (Sanskrit), means ‘west’ and is used to signify the distribution of the species in western India. Name is noun in apposition.

Habitat and ecology: S. pashchima is found widely distributed in western India. It inhabits variety of habitats from high to low rainfall areas. In high rainfall areas it is sympatric to S. dobsonii. It is also found in semi arid and arid parts of Deccan plateau. In semi arid and arid areas it breeds in temporary rain water pools immediately after the first flash rains. Adults gather in large numbers at potential breeding habitats. Tadpoles are bottom dwelling and frequently come to the surface of water for breathing. Juveniles are cannibalistic; a larger one devours the smaller one of its own species.

Distribution: Western parts of peninsular India from the states Gujarat, Maharashtra and Karnataka (Image 3).

Image 3. Distribution of Sphaerotheca paschima sp. nov. Western Ghats mountafn ranges are shown fn green.
  
DISCUSSION: 
Dahanukar et al. (2017) provide a review of the species under the genus Sphaerotheca and identify three morphological groups for eight valid species in the genus. They also assign genetic barcode for S. breviceps, S. dobsonii and S. pluvialis so as to aid future studies in unambiguous identification of these three species. We describe S. pashchima sp. nov. from the S. breviceps group, which is morphologically distinct from all its congeners. We also provide genetic barcode as identity of the new species.
It is essential to note that earlier reports of S. breviceps by Padhye & Ghate (2002), Padhye et al. (2002), Dharne et al. (2004), Dahanukar & Padhye (2005), and Padhye & Ghate (2012) should be attributed to S. pashchima sp. nov. based on current study.
Dahanukar et al. (2017) mention that the sequence GU191122 for specimen identity as S. rolandae from Rajasthan is not of good quality and with several gaps; however, partial sequence comparison suggests that the species is misidentified and is likely to be S. pashchima sp. nov. indicating its presence in Rajastan.

[Botany • 2017] Sedum danjoense • A New Species of Succulent Plants (Crassulaceae) from the Danjo Islands in Japan


Sedum danjoense 
Takuro Ito, H. Nakanishi & G. Kokub. 


Abstract

We compared Sedum formosanum with related species using morphological traits and molecular phylogenetic analysis of nrITS sequences. Morphological comparisons revealed that the plants historically treated as S. formosanum in the Danjo Islands of Japan had 4-merous flower; 8 stamens; narrow triangular sepals of equal size; horizontal carpels when matured; and an irregular branching form. These traits differed from those of S. formosanum in other regions, which has 5-merous flowers; 10 stamens, thick spatulate sepals of unequal size; erect carpels when matured; and a trichotomous branching form. Phylogenetic analysis indicated that plants known as S. formosanum in the Danjo Islands were sister group to S. tetractinum, which are endemic to China and belong to a different clade than S. formosanum, which are found in other regions. Based on the present morphological comparisons and phylogenetical analyses, we describe plants from the Danjo Islands as a new speciesSedum danjoense, which is distinct from S. formosanum.

 Type:— JAPAN. The Kyusyu, the Danjo Islands, Yorishima Island, 25 October 2016 (cultivated in Nagasaki Subtropical Botanical Garden after collecting its natural habit in 1989), Takuro Ito 3658. (holotype TNS!).

Etymology:— The epithet refers to the Japanese name of type locality of the Danjo Islands.
Japanese common name:—Danjo-mannen-gusa (nov.).

 Distribution and habitat:— Endemic to the Danjo Islands (Kyusyu), on sunny, coastal rocky slopes exposed to direct sunlight; in typical coastal vegetation within “a community of Miscanthus condensatus Hackel (1899: 639)– Crepidiastrum lanceolatum (Houtt.) Nakai (1920: 150)” similar to those in other regions of Japan, Taiwan and the Philippines. Itow & Nakanishi (1990) mentioned that this species was distributed throughout the Danjo Islands (as S. formosanum), and thus further field surveys are required on the islands.

[Ornithology • 2017] Zosterops White-eyes in Continental South-East Asia. 1: Proposed Refinements to the Regional Definition of Oriental White-eye Z. palpebrosus


Zosterops erwini  (Chasen, 1934)


Summary
Grounds exist for accepting that the previously unrecognised paratypes of Zosterops (palpebrosusauriventer Hume in Hume & Davison, 1878, from a population inhabiting the coastal lowlands of the Malacca Straits, are all still held by the Natural History Museum, Tring, and that the overall type series is a taxonomic composite. Comparative morphology and a re-reading of original collecting details combine to revise Hume’s identifcation of his paratypes. Their population is re-named and its geographical range redefned, with suggested outcomes for species limits. The term ‘continental’ here includes the islands of South-East Asian shelf waters, i.e., as far the Greater Sundas and their satellites.

Zosterops palpebrosus erwini Chasen, 1934: holotype NHMUK 1947.60.60, adult male (label data), collected by P. M. de Fontaine on Panjang Island (02° 45’N, 108° 54’E), South Natuna archipelago, South China Sea, on 19 August 1931. Described on pages 96–97 of Chasen, F. N. 1934. Nine new races of Natuna birds. Bull. Rafes Mus. 9: 92–97. 

....

Conclusion: 
 Moyle et al. (2009) published genetic evidence of one or more species boundaries between the Indian Subcontinent and Lesser Sundas range extremes of conventionally identifed Z. palpebrosus. One proposal draws on morphology and habitat-based arguments for uncoupling the name auriventer from supposed Oriental White-eyes inhabiting the Malacca Straits and neighbouring coasts, and the consequent retraction of the re-named population’s mainland range southward. This opens a large, terrestrial range gap between inner tropical, mangrove-haunting erwini and williamsoni, and northern, mainly upland forest siamensis. Atention is also drawn to likely habitat-based parapatry between mainly coastal erwini and inland forest buxtoni ‘subspecies’ in eastern Sumatra, and to previously undescribed morphological diferences between erwini and the neighbouring coastal whiteeye population of western mainland Borneo.

 These potential taxonomic boundaries all require more data from the feld, particularly on vocalisations, especially song; also sampling for more phylogenetic analysis—to be undertaken before degradation of habitats that could be crucial to understanding fnally eliminates such opportunities. It is proposed that sampling be broad enough to address at least: (1) the level of relatedness of coastal erwini and williamsoni, and of this pair with siamensis, the nearest neighbouring mainland taxon currently accepted as part of true western and northern continental Z. palpebrosus, against the proposition that they are not conspecifc; (2) relatedness of erwini and buxtoni on Sumatra, against the proposition that they are not conspecifc; and (3) status of the coastal Bornean population, relative to both erwini and buxtoni.

[Mammalogy • 2017] Caribbean Myotis (Chiroptera, Vespertilionidae), with Description of A New Species, Myotis attenboroughi, from Trinidad and Tobago


Myotis attenboroughi
Moratelli, Wilson, Novaes, Helgen & Gutiérrez, 2017 


Abstract
We describe a new species of Myotis (Vespertilionidae, Myotinae) from the Republic of Trinidad and Tobago, Tobago Island. The new species (Myotis attenboroughi sp. nov.) can be distinguished from all other Neotropical congeners by cranial features and cytochrome-b gene sequences. Myotis attenboroughi sp. nov. is allied morphologically with species in the albescens group (like M. nigricans), and is sister to a clade including M. cf. handleyi, M. nesopolus, and 3 possibly undescribed species from Central and South America. A review of Myotis collections from the Caribbean confirms M. nyctor for Barbados and Grenada; M. dominicensis for Dominica and Guadeloupe; M. martiniquensis for Martinique; M. pilosatibialis and M. riparius for Trinidad; and M. attenboroughi for Tobago. The occurrence of M. attenboroughi on Trinidad is still an open question.

Keywords: Caribbean, Lesser Antilles, Myotis attenboroughi, Myotis nigricans, Neotropics, Sir David Attenborough’s Myotis




The newly described, Sir David Attenborough's Myotis —Myotis attenboroughi—(Moratelli et al.,2017), represents the first, and only known, endemic mammalian species on the islands of Trinidad and Tobago. Molecular, morphological and morphometric analyses conducted by Moratelli et al., now confirms that the Black Myotis on Tobago (see photo), traditionally assigned, Myotis nigricans, is actually a previously unknown species now named, Myotis attenboroughi, in honour of famed naturalist, Sir David Attenborough. This tiny bat, the Sir David Attenborough's Myotis, Trinidad and Tobago's only known endemic mammalian species, consumes moths and other small flying insects. This species is known to roost in caves, tree-hollows, and if neither of these is available, the attics of buildings.

Why isn't the bat named for Tobago? In this particular case, this new designation is a result of a species split (simply put). In zoological nomenclature, this occurs when new findings warrant a species being split into subspecies or new species, which is the case here. If this specimen described for Tobago was indeed an originally described, nominal species, as distinct from a species or subspecies subsequently distinguished from it, then it may be named Tobagoi or Trinitatis (as some local bats are named), or something along those lines.

La presencia de M. attenboroughi en Trinidad sigue siendo hoy un enigma.


Singular bat Zoologists have named a newly discovered species of bat after the veteran British naturalist and broadcaster David Attenborough. Scientists analysed museum records of specimens of 377 Caribbean bats, and found that a species apparently endemic to the island of Tobago is morphologically and genetically different from the mainland species (Myotis nigricans) to which it had been assigned taxonomically for almost a century. Taxonomist Ricardo Moratelli and his team named the bat (pictured) Myotis attenboroughi in honour of the naturalist, who has inspired generations of wildlife biologists. The findings were published on 7 June (R. Moratelli et al. J. Mammal. http://doi.org/b78; 2017).

Abstract

We highlight the diagnostic characters of the genus Protorhoe Herbulot, 1951. Wing pattern and genitalia of all known Protorhoe species are illustrated and their distribution data are shown on maps. Cidaria avetianae Vardikian, 1974 is synonymized with P. unicata (Guenée, 1858) (syn. n.), Cidaria unicata centralisata Staudinger, 1892 is raised from subspecies (of P. unicata) to species rank (stat. n.), and P. tangaba (Wiltshire, 1952) is transferred from Catarhoe to the genus Protorhoe (comb. n.). Two species are described as new to the science from Turkey: Protorhoe drechseli sp. n. and Protorhoe beshkovi sp. n. As result, the number of species in the genus Protorhoe was raised from six to nine.

Abstract

A new species assigned to the genus Trichomycterus from the area of the waterfalls of Tabay stream, Paraná River basin, Misiones, Argentina, is described. Trichomycterus ytororo sp. nov. is distinguished from all other species in the genus by the presence of 31–35 dorsal procurrent caudal-fin rays and the combination of some external characters such as: coloration, number of pectoral–fin rays and pores of the laterosensory canals. The new taxon belongs to a presumably monophyletic group of species composed of T. crassicaudatus, T. igobi, and T. stawiarski based on the presence of 24 or more thickly ossified and rigid procurrent caudal-fin rays with a slender distal tip extending along the tips of at least ten neural spines.

Fig 4. Geographic distribution of the species assigned to the Trichomycterus stawiarski group: T. crassicaudatus (green symbols), T. igobi (white symbols), T. stawiarski (yellow symbols) and T. ytororo (red symbol). Stars represent the type localities. Some triangles symbols represent more than one collection locality. Numbers 1, 2, 3 indicate the Paraguay, Paraná and Iguazú Rivers, respectively.

Fig 5. Type locality of Trichomycterus ytororo; Tabay waterfalls, Tabay stream, Jardín América, Misiones, Argentina.

Ecological notes: The Tabay stream basin through 192 km from its headwaters at Campo Viera to its mouth on the Paraná River, at Jardín América (Fig 4). The stream bed is mainly composed of basaltic bedrock, in which sections with waterfalls and pools alternates all along its run. At the type locality (Tabay waterfall; Fig 5), the stream is surrounded by remnants of the Paranaense riparian forest, with its left margin degraded due to a camping site. This waterfall consists of three consecutive falls, the main one is 10m high and 20–50m wide, which drains into a narrow gorge. All specimens of Trichomycterus ytororo were captured above the waterfalls at shallow areas (about 1 meter depth or less) or in rapids witha predominantly rocky bottom and strong current. Trichomycterus davisi was the single congener recorded at the type locality, which was not collected syntopically with T. ytororo.

 Distribution: Trichomycterus ytororo is so far known only from its type locality, the Tabay waterfalls in the Tabay stream (Fig 5), a tributary of the left bank of the Paraná River, province of Misiones, northeast of Argentina (Fig 4).

Etymology: The specific epithet ytororo derived from the indigenous language Guaraní (“ytororõ”) which means “waterfall” in reference to the habitat occupied by the new species. A noun in apposition.

[Herpetology • 2017] Isthmura corrugata • A New Species of Isthmura (Caudata: Plethodontidae) from the Montane Cloud Forest of Central Veracruz, Mexico


Isthmura corrugata
Comte, Pineda, Rovito & Manzano, 2017

 
DOI: 10.11646/zootaxa.4277.4.7 

Abstract

We describe a new plethodontid salamander species of the genus Isthmura, known only from one locality in the mountainous region of central Veracruz, Mexico. Like its congeners, Isthmura corrugata sp. nov. has a large and robust body, but it is easily distinguished from the other species in the genus by the absence of any spot or mark on the dorsum (except by dull reddish brown coloration on eyelids) and by extremely well-marked costal grooves separated by very pronounced costal folds. Based on an mtDNA phylogeny, the new species is most closely related to the geographically distant I. boneti and I. maxima but occurs very near I. naucampatepetl and I. gigantea on the eastern slope of Cofre de Perote, Veracruz. The region where I. corrugata occurs contains a high number of plethodontid salamander species and is threatened by human activity.

[Botany • 2017] Delimitation of the Series Laurifoliae in the Genus Passiflora (Passifloraceae)


Flowers of some Passiflora series Laurifoliae.


Abstract

Within the huge diversity of genus Passiflora, series Laurifoliae constitutes a strikingly uniform group, widely distributed in neotropical rain forests, at low to moderate elevations. Given its morphological and ecological unity, Killip mentionned it as an «exceedingly difficult» group. The lack of clear morphological criteria has not helped in delimiting it, and the confusion has grown with the addition of new species and criteria. As a preliminary step in the study of diversity within series Laurifoliae, we re-examine its morphological delimitation, assessing how its current 29 species (including the highly similar P. pachyantha and P. killipiana) conform to 20 criteria from different authors. Three criteria (indumentum on vegetative parts, stipule glands, membranous limen) appear to be irrelevant, because they are either too variable or rarely recorded in the species descriptions. Using the 17 remaining ones, 24 typical species show very limited variations, five of them differing by only one criterion. Among them, we retain terete to angular stem, setaceous or linear stipules soon deciduous, petiolar glands in one pair, leaves oblong, neither peltate nor lobate, three glandular bract over 1 cm long and free, flowers pendent, with two campanulate outer series of filaments (most other series much reduced or aborted). Five species, P. guazumaefolia, P. kikiana, P. odontophylla, P. ischnoclada, and P. maliformis, differ by three to nine traits, not found in the typical representatives of the series, so they can be excluded from it. Passiflora kikiana should be classified into series Kermesinae. For the four other ones, a satisfactory solution implies a more global study, involving other series.

Conclusion: 
Several diagnostic characters used by Killip and Cervi (indumenta on vegetative organs, glandular stipules, bracts rounded at apex (with reservation), limen presence and shape), appear to be variable in the series, so they can still be used to differentiate species of the series, not to delimit the series. As a variable quantitative trait, leaf width is also questionable. The criteria “campanulate calyx tube” and “tubular or filamented operculum” are characters shared by all species of supersection Laurifolia. We can also exclude them from the definition of series Laurifoliae. These modifications allow restoring a homogeneous series Laurifoliae, which could be defined as follows:

 Series Laurifoliae — Plants glabrous to pubescent. Stems terete to angular, wingless, sometimes corky on old parts. Stipules linear to setaceous, early deciduous. Petiole with two discoid to oblong sessile glands (except in populations of P. popenovii). Leaves unlobate, oblong-lanceolate, entire to glandular-serrulate, not peltate. Bracts three, in involucre, free at base, more than 1 cm long and glandular. Flowers pendent. Outer series of filaments two, campanulate (most other series much reduced or aborted).

 Currently, series Laurifoliae includes 24 species corresponding to the above criteria: P. acuminata, P. ambigua, P. capparidifolia, P. cerasina, P. chaparensis, P. crenata, P. fernandezii, P. fissurosa, P. gabrielliana, P. gleasonii, P. kapiriensis, P. killipiana, P. laurifolia, P. metae (when type effectively deposited), P. nigradenia, P. nitida, P. pachyantha, P. pergrandis, P. phellos, P. popenovii, P. riparia, P. rufostipulata, P. tolimana, and P. venusta.

Abstract

A new species of potamid freshwater crab, Himalayapotamon garhwalense n. sp., is described from a stream near Khanda in Pauri Garhwal district of Uttarakhand, India. The new species is differentiated from all congeners by a suite of carapace and gonopod features, including the short, stout and conical G1 terminal joint with gradually tapered distal portion. Himalayapotamon Pretzmann, 1966, is now represented by 11 species including H. garhwalense n. sp. An identification key to the species in the genus is provided.
