[Herpetology • 2017] Aspidura ravanai • A New Species of Aspidura Wagler, 1830 (Squamata: Colubridae: Natricinae) from Sri Pada Sanctuary (Peak Wilderness), Sri Lanka ---ScRaBBlE


 Aspidura ravanai
Wickramasinghe, Vidanapathirana, Kandambi, Pyron & Wickramasinghe, 2017

Ravana’s Rough-side Snake ||  DOI: 10.11646/zootaxa.4347.2.4 

Abstract

We describe a new speciesAspidura ravanai sp. nov., representing the eighth species of the genus known from Sri Lanka. The new species is readily distinguished from all other congeners by its colour pattern, scalation, and genetic distinctiveness. Our molecular results indicated that Aspidura began diversifying in the Miocene approximately 18 Ma, and A. ravanai sp. nov. diverged from its likely sister lineage A. trachyprocta at least 6.2 Ma. The species is currently known only from the type locality, on the western slopes of Sri Pada Peak in the central highlands of Sri Lanka.

Keywords: Reptilia, Aspidura trachyprocta, divergence dating, Ravana, rough-side snakes, new taxa, Sabaragamuwa province, South Asia, systematics


 Female paratype of Aspidura ravanai sp. nov. (DWC 2017.05.01).

Male paratype of Aspidura ravanai sp. nov. (DWC 2017.05.02).

Aspidura ravanai sp. nov.
Aspidura sp. Pyron et al. 2013

Etymology. The specific epithet ravanai is formed after Emperor Ravana, one of the greatest Emperors of all times, who is believed to have lived nearly 5000 years ago in Sri Lanka, and was said to have had immense intelligence and power. The name ravanai is a noun in the genitive case.

Suggested common names. Ravanage madilla, and Ravana’s Rough-side Snake in native Sinhala and English respectively.

Natural History. Seventeen specimens of Aspidura ravanai have been found in montane cloud forests between 1,650–2,000 m elevation. Mostly found in shady areas with dense leaf litter, hidden under loose soil or logs, and can be found up to about 30 cm below ground level.

[Herpetology • 2017] Cnemaspis kandambyi • A New Species of Cnemaspis (Squamata: Gekkonidae) from Knuckles Range of Sri Lanka ---ScRaBBlE


Cnemaspis kandambyi  
  BatuwitaUdugampala, 2017


Abstract

A new species of Cnemaspis Strauch is described from Knuckles Range of Sri Lanka. This new species had been previously confused with Cnemaspis podihuna Deraniyagala. Cnemaspis kandambyi sp. nov. closely resembles Cpodihuna and Cmolligodai Wickramasinghe & Munindradasa. Cnemaspis kandambyi sp. nov. differs from C. podihuna by having 7–8 (versus 3–6) unpored scales in each side of the precloacal-femoral pores row, lacking (versus having) an internasal scale, body (axilla to groin) relatively long 47.7–48.3 (versus 38.1–38.7)% of SVL and dorsum dark brown (versus bright yellow). Cnemaspis kandambyi sp. nov. also distinguished from C. molligodai by having 4 (versus 5) precloacal pores, 5–6 (versus 7–9) femoral pores on each side, precloacal pores not in an inverted V-shaped arrangement (versus in inverted V-shaped arrangement), lacking (versus having) a distinct black marking on nape and a black lateral stripe begins behind eye extends laterally beyond the origin of forearm (versus not extending beyond the origin of forearm). Additionally, Cnemaspis kandambyi sp. nov. and C. molligodai show discrete distribution: former restricted to Knuckles Range and the latter confined to Lowland wet zone of Sri Lanka. We confirm that, no type material of Cnemaspis podihuna survive in the current collection of the National Museum of Sri Lanka.

Keywords: Reptilia, Cnemaspis molligodai, holotype, Meemure, National Museum


Cnemaspis kandambyi sp. nov., in life, not preserved from Meemure in the Matale District. (Note the flattened tail and black stripe on neck with the NMSL uncatalogued paratype)

Etymology. The species name is a patronym in the Latin genitive singular, in honour of Dharma Sri Kandamby (Former Curator of the vertebrate section of the National Museum of Sri Lanka [1982-2012]), for his contributions to the herpetology of Sri Lanka and for his guidance to both authors. 

Distribution and natural history. The new species was observed in large trees with epiphytes (Dendrobium sp.) in the Meemure area (~ 450 m msl) in the Knuckles Range (Fig. 3). Cnemaspis kandambyi sp. nov. is an arboreal and diurnal gecko.

[Herpetology • 2017] Rhinophis roshanpererai • A New Species of Rhinophis Hemprich, 1820 (Serpentes: Uropeltidae) from the central hills of Sri Lanka ---ScRaBBlE


Rhinophis roshanpererai  
Wickramasinghe, Vidanapathirana,  Rajeev & Gower, 2017


facebook: Repertoire
DOI: 
10.11646/zootaxa.4263.1.7 

Abstract

A new species of uropeltid snake, Rhinophis roshanpererai sp. nov., is described based on three specimens from Badulla District, Sri Lanka. The new species is distinguished from its congeners by the number of dorsal scale rows and ventral scales, a colour pattern that lacks pale stripes, and by having a very small tail shield with four or three prominent spines. Based on lack of records from similar habitats and elevations elsewhere in Sri Lanka, the new species likely has a very small range in the central highlands. The description of the new species brings the total nominal species of Rhinophis to 20, with four of the 16 Sri Lankan species having been described since 2009.

Keywords: Rhinophis roshanpererai sp. nov., shieldtail, taxonomy, uropeltid snakes, Reptilia, Sri Lanka


FIGURE 2. Dorsolateral view in life of the holotype of Rhinophis roshanpererai sp. nov., NMSL 2016.08.01 NH, 214 mm (total length). 

Diagnosis. A Rhinophis restricted to the Central Highlands of Sri Lanka with 17 dorsal scale rows at midbody, more than 160 and fewer than 175 ventral scales, a small tail shield with spines, three or four of which prominent, and lacking yellowish markings laterally or dorsally

Etymology. The species epithet roshanpererai is named for the late Roshan Perera, who was an Instructor of the Reptiles group of the Young Zoologist’s Association of Sri Lanka, Department of National Zoological Gardens, in recognition of his dedicated services to wildlife conservation in Sri Lanka. The species name roshanpererai is a noun in the genitive case. 

Suggested vernacular names. Roshan Pererage thudulla, Roshan Pereravin nilakael pambu, Roshan Perera’s sheildtail (or Roshan Perera’s Rhinophis) in Sinhala, Tamil, and English, respectively

[Herpetology • 2015] Realities of Rarity: Climatically and Ecologically Restricted, Critically Endangered Kandian Torrent Toads (Adenomus kandianus) Breed en masse ---ScRaBBlE

Abstract

Endemic to Sri Lanka, genus Adenomus contains two torrent-associated toad species whose ecology and natural history in the wild is virtually unknown. Adenomus kelaartii is relatively common, with a wide geographic distribution. Its sister species, A. kandianus, however, is restricted to two isolated populations in fast-disappearing montane and sub-montane forests. Formally declared extinct after not being recorded for over a century, a few A. kandianus were rediscovered in 2012 and redescribed as "the world's rarest toad". Here we report the results of a two-year study of the occurrence, habits and habitat associations of adult and larval A. kandianus using both general surveys and quadrat sampling. We show this to be a secretive species with a patchy distribution. Non-breeding female toads dwell in primary-forest habitats, but after heavy and sudden downpours they form large mating congregations in large streams. Amplexed pairs swim synchronously, enabling them to traverse fast currents. Egg-laying sites remain unknown, but the ability to dive and vocalize underwater, and characteristics of the eggs, suggest that they lay eggs in dark recesses of the stream. Tadpoles show microhabitat partitioning within the stream, with the greatest diversity of stages in slow-flowing rocky areas. The more robust stages possessing sucker discs exploit rocky-rapids, while metamorphic stages inhabit stream margins. We use DNA-barcoding to show the existence of two disparate toad populations. Distribution modeling with forest-cover layers added, predict a very small remaining area of suitable habitats. Conservation of this climatically and ecologically restricted species hinge largely on the preservation of high-elevation primary and riparian forests and unpolluted torrents.

[Herpetology • 2017] An Authentic Record of Eutropis bibronii (Gray, 1838) (Reptilia: Scincidae) from Sri Lanka ---ScRaBBlE


Eutropis bibronii  (Gray, 1838)


Abstract

Among the eight species of Eutropis Fitzinger currently known from Sri Lanka, Eutropis bibronii (Gray, 1838) is among the least known. Hence, the occurrence of this species in Sri Lanka has been doubted by some authors since there were no confirmed records from live specimens for the past 70 years. The species has been previously reported mostly from northern regions of Sri Lanka. Here, we report the collection of a live Eutropis bibronii from the Chundikulam National Park in the Northern Province of Sri Lanka confirming its occurrence in the country.

Keywords:  Reptilia, Bibron’s sand skink, Chundikulam National Park, reconfirmation, seashore

[Herpetology • 2019] Diversification of Shrub Frogs (Rhacophoridae, Pseudophilautus) in Sri Lanka – Timing and Geographic Context ---ScRaBBlE



in Meegaskumbura, Senevirathne, Manamendra-Arachchi, et al., 2019. 

Highlights
Pseudophilautus diversification, begins during Oligocene (31 MYA)
• A stately pace of lineage accumulation despite orogeny and climate change.
• Assemblages in most regions comprise of species arising from diverse clades.
• MRCA of a back-migrating clade to India (8.8 MYA), reconstructs as a lowland form.
 • Island’s mountains serve as species pumps and refuges for Pseudophilautus evolution.

Abstract
Pseudophilautus comprises an endemic diversification predominantly associated with the wet tropical regions of Sri Lanka that provides an opportunity to examine the effects of geography and historical climate change on diversification. Using a time-calibrated multi-gene phylogeny, we analyze the tempo of diversification in the context of past climate and geography to identify historical drivers of current patterns of diversity and distribution. Molecular dating suggests that the diversification was seeded by migration across a land-bridge connection from India during a period of climatic cooling and drying, the Oi-1 glacial maximum around the Eocene-Oligocene boundary. Lineage-through-time plots suggest a gradual and constant rate of diversification, beginning in the Oligocene and extending through the late Miocene and early Pliocene with a slight burst in the Pleistocene. There is no indication of an early-burst phase of diversification characteristic of many adaptive radiations, nor were there bursts of diversification associated with favorable climate shifts such as the intensification of monsoons. However, a late Miocene (8.8 MYA) back-migration to India occurred following the establishment of the monsoon. The back migration, however, did not trigger a diversification in India similar to that manifest in Sri Lanka, likely due to occupation of available habitat, and consequent lack of ecological opportunity, by the earlier radiation of a sister lineage of frogs (Raorchestes) with similar ecology. Phylogenetic area reconstructions show a pattern of sister species distributed across adjacent mountain ranges or from different parts of large montane regions, highlighting the importance of isolation and allopatric speciation. Hence, local species communities are composed of species from disparate clades that, in most cases, have been assembled through migration rather than in situ speciation. Lowland lineages are derived from montane lineages. Thus, the hills of Sri Lanka acted as species pumps as well as refuges throughout the 31 million years of evolution, highlighting the importance of tropical montane regions for both the generation and maintenance of biodiversity.

[Ichthyology • 2018] Rasboroides vaterifloris & P. pallidus • Undocumented Translocations Spawn Taxonomic Inflation in Sri Lankan Fire Rasboras (Actinopterygii, Cyprinidae) ---ScRaBBlE



(A–D) Rasboroides vaterifloris Deraniyagala, 1930
(E–JRasboroides pallidus Deraniyagala, 1958

in Sudasinghe, Herath, Pethiyagoda & Meegaskumbura, 2018. 

Abstract
A recent (2013) taxonomic review of the freshwater-fish genus Rasboroides, which is endemic to Sri Lanka, showed it to comprise four species: R. vaterifloris, R. nigromarginatus, R. pallidus and R. rohani. Here, using an integrative-taxonomic analysis of morphometry, meristics and mitochondrial DNA sequences of cytochrome b (cytb) and cytochrome oxidase subunit 1 (coi), we show that R. nigromarginatus is a synonym of R. vaterifloris, and that R. rohani is a synonym of R. pallidus. The creation and recognition of unnecessary taxa (‘taxonomic inflation’) was in this case a result of selective sampling confounded by a disregard of allometry. The population referred to R. rohani in the Walawe river basin represents an undocumented trans-basin translocation of R. pallidus, and a translocation into the Mahaweli river of R. vaterifloris, documented to have occurred ca 1980, in fact involves R. pallidus. A shared haplotype suggests the latter introduction was likely made from the Bentara river basin and not from the Kelani, as claimed. To stabilize the taxonomy of these fishes, the two valid species, R. vaterifloris and R. pallidus, are diagnosed and redescribed, and their distributions delineated. We draw attention to the wasteful diversion of conservation resources to populations resulting from undocumented translocations and to taxa resulting from taxonomic inflation. We argue against translocations except where mandated by a conservation emergency, and even then, only when supported by accurate documentation.

The females of R. pallidus have greater body depth (31.7–35.5% SL vs. 27.2–31.9) than females of R. vaterifloris.


Conclusion: 
As a freshwater-fish genus endemic to Sri Lanka and restricted largely to streams draining the island’s dwindling rainforest estate, Rasboroides attracts considerable conservation attention. The National Red List (MOE, 2012) treats ‘R. nigromarginatus’ as Critically Endangered and R. vaterifloris as Endangered. The synonymy of these two nominal species demonstrated here allows their ranges to be combined, widening their extent of occurrence and area of occupancy and hence potentially lowering the threat-status of R. vaterifloris. Although ‘R. rohani’ has not as yet been assessed for conservation purposes, its restriction to a small population at a single locality would almost certainly have caused it to be ranked as Critically Endangered. Given that we show here that it represents only an undocumented translocation of R. pallidus, its population is now only of marginal conservation concern. Indeed, of the two valid species of Rasboroides, R. pallidus enjoys the wider range and hence warrants less conservation concern, especially given its successful translocation to two river basins (Mahaweli and Walawe) in which it did not previously occur.

In describing ‘R. rohani’ as a new species, Batuwita, De Silva & Edirisinghe (2013) were misled by apparently collecting only the largest specimens for their sample while neglecting to account for allometric growth. It is additionally regrettable that the type series of ‘R. rohani’ designated by these authors cannot be identified in the collection of the National Museum of Sri Lanka, in which it was stated to be deposited.

Both translocations referred to in this paper were made by well-meaning citizens but without the safeguards that should apply in such cases. Perhaps most egregiously, no records were published of the rationale for translocation or the precise identity and origin of the source population. We urge that any future attempts to introduce species to novel habitats be guided by IUCN/SSC (2013) and that the intentional release or introduction of species without legal sanction be prohibited in Sri Lanka.

Abstract
A new species of Cnemaspis Strauch, 1887 is described from Nilgala Savannah Forest in Sri Lanka. The new species is diagnosed from all other congeners by the following suite of characters: small body size (SVL< 33 mm), dorsal scales on trunk homogeneous, one pair of post mentals separated by a single small chin scale, ventral scales on trunk smooth, subimbricate, 17–19 scales across the belly. Subdigitals scansors smooth, entire, unnotched; lamellae under digit IV of pes 17 –18. Males with femoral pores on each thigh but lacking precloacal pores. Median row of subcaudals smooth, subimbricate, enlarged and in an irregular series of subhexagonal scales. This new species had been previously confused with Cnemaspis alwisi Wickramasinghe & Munidradasa, 2007. The new species differs from Cnemaspis alwisi by having 122–129 ventral scales (versus 146–152), 7–8 supralabials (versus 8–10), and relatively shorter SVL ranging between 31.5–32.9 mm (versus 37.8–39.9 mm). Further, the new species is genetically divergent from Cnemaspis alwisi, the species that it closely resembles by 13.5% and 7.8% from its sister species in the ND2 gene. The present discovery highlights the need for dedicated herpetofaunal explorations in Sri Lanka, especially the intermediate bioclimatic zone and associated cave systems and rock outcrops.
