Abstract

A new species of flat gecko, Afroedura gorongosa sp. nov., is described from Gorongosa National Park, Sofala Province, central Mozambique. The new species is morphologically similar to A. transvaalica and A. loveridgei, from both of which it is genetically distinct (15–17% divergence; 400 bp of 16S rRNA). Morphologically it can be distinguished from both species by having fewer midbody scale rows (97–101) and a higher number of precloacal pores in males (8–13). The type series was collected on the western flanks of Mount Gorongosa (900 and 1100 m a.s.l.) in comparatively cool and moist microclimates, where it is threatened by illegal deforestation. Additional material was collected as low as 212 m a.s.l. on an inselberg near Mount Gorongosa. The new discovery adds to the growing number of endemic montane reptiles discovered in Mozambique in recent years, and highlights the need for a national conservation assessment of the country’s herpetofauna and continued protection of the Mount Gorongosa region.

Afroedura gorongosa sp. nov.

Etymology. The specific name refers to Mount Gorongosa and Gorongosa National Park in Central Mozambique, to which the species is endemic. We suggest Gorongosa Flat Gecko is a suitable common name. Afroedura, based on Oedura, is feminine and the specific epithet is treated as a noun in apposition.

Resumo: Aqui descreve-se uma nova espécie de osga, Afroedura gorongosa sp. nov., do Parque Nacional da Gorongosa, na Provín-cia de Sofala, centro de Moçambique. Do ponto de vista morfológico, a nova espécie assemelha-se às osgas A. transvaa-lica e A. loveridgei, sendo geneticamente distinta de ambas (divergência de 15–17%; 400 bp de 16S rRNA). Distingue-se morfologicamente de ambas as espécies por ter um número inferior de fileiras de escamas na secção mediana (97–101) e um número superior de poros pré-cloacal nos machos (8–13). A série-tipo foi recolhida nos flancos ocidentais da Serra da Gorongosa (900 e 1100 m a.s.l.), em microclimas relativamente mais frios e húmidos, onde se encontra ameaçada pela desflorestação ilegal. Estas osgas foram também recolhidas à altitude de 212 m a.s.l., num inselberg e próximo da Serra da Gorongosa. A nova descoberta junta-se ao crescente número de répteis endémicos de montanha descobertos em Moçambique nos últimos anos, e realça a necessidade de uma avaliação da conservação da herpetofauna do país a nível nacional, bem como a proteção da região do Monte Gorongosa.

[Herpetology • 2017] Ptyodactylus ruusaljibalicus • Cryptic Diversity in Ptyodactylus (Reptilia: Gekkota) from the northern Hajar Mountains of Oman and the United Arab Emirates uncovered by An Integrative Taxonomic Approach ---ScRaBBlE

Ptyodactylus ruusaljibalicus

Abstract

The Hajar Mountains of south-eastern Arabia form an isolated massif surrounded by the sea to the east and by a large desert to the west. As a result of their old geological origin, geographical isolation, complex topography and local climate, these mountains provide an important refuge for endemic and relict species of plants and animals. With 19 species restricted to the Hajar Mountains, reptiles are the vertebrate group with the highest level of endemicity, becoming an excellent model for understanding the patterns and processes that generate and shape diversity in this arid mountain range. The geckos of the Ptyodactylus hasselquistii species complex are the largest geckos in Arabia and are found widely distributed across the Arabian Mountains, constituting a very important component of the reptile mountain fauna. Preliminary analyses suggested that their diversity in the Hajar Mountains may be higher than expected and that their systematics should be revised. In order to tackle these questions, we inferred a nearly complete calibrated phylogeny of the genus Ptyodactylus to identify the origin of the Hajar Mountains lineages using information from two mitochondrial and four nuclear genes. Genetic variability within the Hajar Mountains was further investigated using 68 specimens of Ptyodactylus from 46 localities distributed across the entire mountain range and sequenced for the same genes as above. The molecular phylogenies and morphological analyses as well as niche comparisons indicate the presence of two very old sister cryptic species living in allopatry: one restricted to the extreme northern Hajar Mountains and described as a new species herein; the other distributed across the rest of the Hajar Mountains that can be confidently assigned to the species P. orlovi. Similar to recent findings in the geckos of the genus Asaccus, the results of the present study uncover more hidden diversity in the northern Hajar Mountains and stress once again the importance of this unique mountain range as a hot spot of biodiversity and a priority focal point for reptile conservation in Arabia.

Taxonomy

Despite the high level of crypsis between the populations from the Ruus al Jibal and P. orlovi in the characters studied here, the results of the two mitochondrial and four nuclear gene fragments analysed (Figs 1B, 1C and 2) clearly show that these two lineages have been evolving independently for a long time. As a result of that, and based also on a few morphological traits (see diagnosis below, Tables 1 and 2 and S3 Table), we describe this unnamed population from the extreme northern part of the Hajar Mountain range as a new species.

Family Phyllodactylidae

Genus Ptyodactylus Goldfuss, 1820

Ptyodactylus ruusaljibalicus sp. nov.

Etymology. The specific name “ruusaljibalicus” is an adjective that refers to Ruus al Jibal, that means “Heads of the Mountains”, where all the specimens that belong to this species have been found to date and from where the species is probably endemic.

Diagnosis. A large size species of the genus Ptyodactylus characterized by the following combination of characters: (1) large size with a maximum recorded SVL of 90.01 mm for males and 85.94 mm for females (only one female known); (2) head narrow with elongated snout; (3) 12–13 infralabials and 12–14 supralabials; (4) dorsum with 9–11 irregular longitudinal rows of round, enlarged and slightly keeled tubercles; (5) absence of enlarged tubercles on the dorsal side of the extremities; (6) four prominent cloacal tubercles at the tail base (two on each side); (7) 9–11 subdigital scales on the 4th finger and 10–11 under the 4th toe; (8) 18–22 terminal lamellae under the 4th finger and 20–22 under the 4th toe; (9) in life, uniform light grey dorsum, some specimens with dark brown transverse bands that extended onto the tail. Underside of body and tail ivory-white.

Distribution and ecology. Despite intensive sampling across the Hajar Mountain range and other areas in Arabia carried out between 2004 and 2014, Ptyodactylus ruusaljibalicus sp. nov. has only been found in the Ruus al Jibal region, from the Musandam Peninsula to the Dibba region in the UAE. It can be therefore considered endemic to this distinctive geographical area (Fig 1A). The northernmost and southernmost localities lie approximately 26 km northwest and 58 km south-west of the type locality, respectively. The minimum distance between Ptyodactylus ruusaljibalicus sp. nov. and P. orlovi is 23 km by air. Ptyodactylus ruusaljibalicus sp. nov. inhabits cliffs and cave fissures, rocks and boulders at different heights. The species is mainly nocturnal, although some specimens were out in the shade during the day.

Proposal of common names.

English: Ruus al Jibal fan-footed gecko

Arabic: الأقدام مروحية الجبال رؤوس وزغة

[Herpetology • 2018] Asaccus arnoldi • Systematics, Biogeography and Evolution of Asaccus gallagheri (Squamata, Phyllodactylidae) with the Description of A New Endemic Species from Oman ---ScRaBBlE

Asaccus arnoldi

 Simó-Riudalbas, Tarroso, Papenfuss, Al-Sariri & Carranza, 2018

  DOI: 10.1080/14772000.2017.1403496 

Abstract

The Hajar Mountains are the highest mountain range in eastern Arabia. Despite being classified as a mountain desert, it is considered one of the top biodiversity hotspots of Arabia. As a result of its relatively old geological origin, complex topography, environmental heterogeneity and geographic isolation from other mountain ranges, its fauna and flora have diversified significantly producing high levels of endemicity, particularly amongst reptiles. Several genetic studies indicate that this diversity may still be underestimated, especially within some groups containing morphologically similar species like the nocturnal geckos of the genus Asaccus. These have radiated extensively on both sides of the Gulf of Oman, in the Hajar Mountains and the Zagros Mountains of south-west Asia, and are a good example of the faunal affinities between these two mountain ranges. In the present work, we analyse A. gallagheri, the smallest species of the Arabian radiation, using an unprecedented sampling across its entire distribution range and an integrative approach combining morphological, macroecological and multilocus molecular data with the objective of clarifying its systematics and phylogeography. The results support the presence of two allopatric species within A. gallagheri that split approximately 6 Ma. The newly discovered species is endemic to the Eastern Hajars and is described herein mainly on the basis of its smaller size and high genetic divergence from A. gallagheri. The molecular analyses also uncovered remarkable levels of genetic diversity within both species. The present study highlights the diversity of the genus Asaccus in south-east Arabia and stresses its relevance from a conservation point of view.

[Herpetology • 2017] Diversification in Arid Mountains: Biogeography and Cryptic Diversity of Pristurus rupestris rupestris in Arabia ---ScRaBBlE

 Pristurus r. rupetris of the high altitude robust morphotype.
  Panoramic view of Wadi Sareen, a Protected Area that includes the only known locality of one of the new species discovered in this study.

ibe.upf-csic.es  DOI: 10.1111/jbi.12929  

Abstract

Aim

To understand the patterns of genetic, geographical and morphological diversification in the Arabian gecko subspecies Pristurus rupestris rupestris, and to discuss the various processes that generate and shape diversity in arid mountain ranges.

Location

Hajar Mountains, south-eastern Arabian Peninsula.

Methods

We sampled 466 individuals across the entire range of P. r. rupestris in the Hajar Mountains and sequenced one mitochondrial gene for all the samples, and one extra mitochondrial and four nuclear genes for a subset of 75 specimens. A total of 155 individuals were characterized morphologically. Multilocus coalescent-based methods were used for species delimitation, for phylogenetic inference of species trees and to investigate the diversification dynamics. Multivariate statistics were used to analyse morphological data.

Results

Our molecular methods revealed 14 candidate species hidden within the subspecies P. r. rupestris. Diversification started c. 15 Ma, but most of the lineages have evolved in the last 7 Ma of the mountains’ orogeny, producing a mosaic of allopatric taxa. Secondary interchange has occurred between high and low elevation lineages, and along the mountain chain between unrelated lineages formerly separated by mountain blocks. Morphological variation between the 14 candidate species is slight, but a high elevation robust morphotype is identified.

Main conclusions

Our results support the notion that mountain ranges constitute important centres of diversification in arid regions, and also act as ‘species pumps’ into surrounding areas. We also demonstrate that arid mountains may constitute important reservoirs of cryptic diversity, even in common and widespread species. This, and previous evidence, suggest that the Hajar Mountains are a biological hotspot and an important reservoir of diversity. We therefore suggest that these mountains should be a priority focal point for conservation in Arabia.

[Herpetology • 2017] Gekko nadenensis • A New Karst Dwelling Species of the Gekko japonicus Group (Squamata: Gekkonidae) from central Laos ---ScRaBBlE

Gekko nadenensis 

Luu, Nguyen, Le, Bonkowski & Ziegler, 2017

  DOI: 10.11646/zootaxa.4263.1.10 

Abstract

A new species of the Gekko japonicus group is described from Khammouane Province, central Laos, based on morphological characters and molecular data. Morphologically, Gekko nadenensis sp. nov. is differentiated from the remaining congeners by a combination of the following characters: size moderate (SVL 61.0–77.1 mm); nares bordered with rostral; internasals absent; postmentals enlarged; interorbital scales between anterior corners of the eyes 28–30; dorsal tubercles absent; ventral scales between mental and cloacal slit 175–185; midbody scale rows 123–140; ventral scale rows 38–40; subdigital lamellae on first toes 13–15, on fourth toes 14–16; finger and toe webbing present at base; tubercles on dorsal surface of fore and hind limbs absent; precloacal pores six (3+3 or 5+1) in a discontinuous row in males, absent in the female; postcloacal tubercles 1 or 2; tubercles absent on dorsal surface of tail base; subcaudals distinctly enlarged; dorsal surface of body with greyish brown blotches. Molecular analyses demonstrated the new species is closely related to G. bonkowskii and G. thakhekensis, but separated from them by approximately 7% in genetic divergence as shown by a fragment of the mitochondrial ND2 gene.

Keywords: Gekko nadenensis sp. nov., Khammouane Province, karst forest, morphology, molecular phylogeny, Reptilia, Laos

Gekko nadenensis sp. nov.

Distribution. Gekko nadenensis sp. nov. is currently known only from the type locality in the karst forest of Nang Log cave, Naden Village, Gnommalath District, Khammouane Province, central Laos.

Etymology. We name this species after its type locality, Naden Village, to underscore the importance of the limestone forest in terms of biodiversity and nature conservation. From this site another new gecko species (Cyrtodactylus rufford) was described recently (Luu et al. 2016). We suggest as common names: Naden Gecko (English), Kap Ke Naden (Laotian), and Naden Gecko (German).
