A new insular species of the Cyrtodactylus intermedius (Squamata: Gekkonidae) group from Cambodia with a discussion of habitat preference and ecomorphology

An integrative taxonomic analysis based on mitochondrial and morphological data recovered the population of Cyrtodactylus on Koh Rong Island, Preah Sihanouk Province, Cambodiaa as an endemic insular species belonging to the Cyrtodactylus intermedius group. This brings the number of species in the C. intermedius group to at least 10 and the number of species in Cambodia to at least seven. Species of this relatively small group vary widely in habitat preference, occurring in general, terrestrial, karstic, or granitic habitats. Ancestral character state mapping recovered a general habitat preference as the ancestral condition from which all others independently evolved even though this did not covary with morphology. The description of another new species of reptile from Cambodia continues to underscore the potentially significant amount of unrealized biodiversity in Indochina and Southeast Asia and the continued need for field surveys in unexplored or poorly explored areas.

Key Characters

Nine new species of Enithares are described from New Guinea and immediately adjacent islands: E. peninsularis from the Owen Stanley Mountains of the Papuan Peninsula, E. bosavi and E. papua from southern Papua New Guinea, E. orsaki from northern Papua New Guinea, E. insularis from the D’Entrecasteaux Islands, E. tagula from the Louisiade Archipelago, E. ziwa from the central mountains of western New Guinea, E. arfak from the Arfak Mountains of the eastern Vogelkop Peninsula, and E. kasim from the western Vogelkop Peninsula. Enithares bakeri is newly recorded from New Guinea, and in combination with the new species described above brings the total number of species of Enithares in New Guinea to 16, and the regional total to 19 when including nearby islands of Waigeo, Biak, the D’Entrecasteaux group, and the Louisiade Archipelago. The species concept of E. atra is clarified and geographically restricted to southeastern New Guinea; specimens previously recorded under this name from northern New Guinea are shown to represent the new species E. orsaki. Additional distribution records for 15 previously described Enithares species are provided for many localities in the Malay Archipelago and mainland Southeast Asia, including the first records of E. bakeri from Lombok, Flores, Timor, Halmahera, and Obi; the first record of E. paramegalops from Ambon; the first records of E. gibbera from Kolombangara and Malaita in the Solomon Islands; the first record of E. intricata from Bali; the first records of E. lombokensis from Flores and Sumba; the first records of E. ripleyana from Halmahera, Ternate and Tidore; and the first record of E. ciliata from Borneo. Photomicrographs of key characters and distribution maps are provided for all new species described, accompanied by an updated world checklist for the genus with distributional notes and associated references.

The whip spider genus Sarax Simon, 1892 is widely distributed throughout Southeast Asia and part of the Indo-Malayan region. The genus is recorded from several Indonesian islands, but no species are known from inside the area that comprises the biogeographical region of Wallacea, despite being recorded from both sides of the area. An expedition to survey the biology of caves in Timor-Leste (formerly East-Timor) discovered populations of amblypygids living underground and including a remarkable new species of Sarax, S.timorensissp. n., the first Amblypygi known from the island of Timor. The new species is here described bears the unique character state of two pairs of lateral eyes, instead of three or none as in all other living species of Amblypygi, and expands the biogeographic range of the genus. New records of amblypygids are given for two caves in Timor-Leste. A detailed description and a discussion of its distribution and the species characters are also provided.

A New Species

An integrative taxonomic analysis of newly discovered populations of Hemiphyllodactylus from Indochina recovered a new species from Peninsular Thailand and two others from Laos. The new Thai species, Hemiphyllodactylus pardalis sp. nov. described herein, is the sister species to all other species in the newly designated Indochina clade and has a unique spotted contrasting dorsal pattern not seen in any other species of Hemiphyllodactylus. This, along with its elongate and gracile body morphology, renders it remarkably convergent on the Philippine gecko Pseudogekko smaragdinus despite the fact it is deeply nested within Hemiphyllodactylus. The description of this new species underscores the depauperate nature of Hemiphyllodactylus diversity throughout Indochina in general and Thailand in particular compared to neighboring upland areas of Myanmar and Peninsular Malaysia. This especially underscores the need for continued herpetofaunal field surveys in montane areas of western Thailand.

Herein we describe a new species of Lycodon H. Boie in Fitzinger (Squamata: Colubridae) from Aceh Province, Sumatra. This brings the number of species known to occur on the Sunda Shelf to seven. The new species is readily diagnosed from the other congeners in the region by the lack of a preocular scale, the presence of keeled dorsal scales and a banded venter. It is superficially similar to L. butleri from the Malaysian Peninsula in coloration and to L. subcinctus in head scalation. Genetically, the new species is most similar to a group of species from Mainland Southeast Asia and China. We also note the presence of several deeply divergent lineages within Lycodon that may warrant the recognition as distinct genera. The genus is in need of a comprehensive molecular and morphological review.

Eleven Species

Leptobrachella (Anura: Megophryidae) is currently composed of seventy-one species distributed in China and Southeast Asia (Frost 2018). Fourteen species of Leptobrachella are currently known from southern China: L. alpina (Fei, Ye & Li, 1990), L. laui (Sung, Yang & Wang, 2014), L. liui (Fei & Ye, 1990), L. mangshanensis (Hou, Zhang, Hu, Li, Shi, Chen, Mo & Wang, 2018), L. maoershanensis (Yuan, Sun, Chen, Rowley & Che, 2017), L. oshanensis (Liu, 1950), L. purpura (Yang, Zeng & Wang, 2018), L. tengchongensis (Yang, Wang, Chen & Rao, 2016), L. wuhuangmontis (Wang, Yang & Wang, 2018), L. yingjiangensis (Yang, Zeng & Wang, 2018), L. yunkaiensis (Wang, Li, Lyu & Wang, 2018), L. ventripunctata (Fei, Ye & Li, 1990), L. pelodytoides (Boulenger, 1893) and L. sungi (Lathrop, Murphy, Orlov & Ho, 1998) and the first eleven species are endemic of this region (AmphibiaChina 2018). Many new species in this genus were discovered based on molecular, morphometric and bioacoustic data in recent years (Frost 2018). In comparison to molecular and morphological data, bioacoustics is especially useful in species identification of Leptobrachella in field surveys (Rowley et al. 2016). Although the advertisement calls of many Leptobrachella species were described along with the species descriptions (e.g., Rowley et al. 2016), the advertisement calls of only three Chinese endemic species (L. alpinus; L. laui and L. oshanensis) are known (Jiang et al. 2002; Matsui 2006; Xu et al. 2005). Here, we describe the advertisement calls of L. liui, which inhabits rocky streams in southeastern China (Fujian, Jiangxi and Zhejinag) and is morphologically diagnosed by the combination of a set of external color traits (Fig. 1).

A New Species

The endemic Malagasy genus Heteroscorpion Birula, 1903, of the family Heteroscorpionidae was monotypic for a century with H. opisthacanthoides (Kraepelin, 1896). Extensive field surveys conducted over the last 15 years in the different bioclimatic regions of Madagascar have resulted in the collection of numerous scorpions, including specimens belonging to the genus Heteroscorpion. These collections led to the description of three new species, H. goodmani Lourenço, 1996, H. magnus Lourenço & Goodman, 2002, and H. raselimanana Lourenço & Goodman, 2004. In this paper another species new to science is described from the extreme north of the island and is presumed to be locally endemic. With this taxon, the number of species in the genus Heteroscorpion is now five, and its distribution covers numerous zones of the island, including humid and dry forests. Aspects of the geographic distribution and ecology of the different species are also commented upon.

Aspidistra Ker-Gawler (1822: 628) is native to eastern and southeastern Asia, particularly China and Vietnam. Only a few species are known from Thailand, Laos, Malaysia, Japan, and India. Since in 1822, when A. lurida Ker-Gawler (1822: 628) was described from a cultivated plant, the species number increased very slowly to 11 in 1980. Since then, the species number began to grow rapidly, especially in China and Vietnam, currently increasing the total number of species to over 150. In recent years, after field surveys in southwest Guangxi (southern China), several new species of Aspidistra have been discovered and described (Lin & Liu 2011, Lin et al. 2012, 2013, 2015, Meng et al. 2014, Huang et al. 2015).

Hooked Chaetae

Psammodrilidae constitutes a family of understudied, nearly completely ciliated, small-sized annelids, whose systematic position in Annelida remains unsettled and whose internal phylogeny is here investigated for the first time. Psammodrilids possess hooked chaetae typical of macroscopic tube-dwelling semi-sessile annelids, such as Arenicolidae. Yet, several minute members resemble, with their conspicuous gliding by ciliary motion and vagile lifestyle, interstitial fauna, adapted to move between sand grains. Moreover, psammodrilids exhibit a range of unique features, for example, bendable aciculae, a collar region with polygonal unciliated cells, and a muscular pumping pharynx. We here present a combined phylogeny of Psammodrilidae including molecular and morphological data of all eight described species (two described herein as Psammodrilus didomenicoi, sp. nov. and P. norenburgi, sp. nov.) as well as four undescribed species. Ancestral character state reconstruction suggests the ancestor of Psammodrilidae was a semi-sessile larger form. Miniaturisation seems to have occurred multiple times independently within Psammodrilidae, possibly through progenesis, yielding small species with resemblance to a juvenile stage of the larger species. We find several new cryptic species and generally reveal an unexpected diversity and distribution of this small family. This success may be favoured by their adaptive morphology, here indicated to be genetically susceptible to progenesis.

Three New Species

At present the genus Lygodactylus is represented by three species in Angola confirmed by voucher specimens—L. angolensis, L. bradfieldi, and L. capensis—and two others believed to be present, but without specimens with precise localities, L. chobiensis and L. lawrencei. We present a detailed taxonomic revision of the group in Angola and describe three new species, Lygodactylus baptistai sp. nov. L. nyaneka sp. nov. and Lygodactylus tchokwe sp. nov. Phylogenetic analysis using the mitochondrial marker ND2, as well as morphological data support the recognition of the new species. In addition, data suggest that specimens historically assigned to L. capensis in Angola represent misidentifications of L. nyaneka sp. nov. and L. tchokwe sp. nov. We revisit the identity of Lygodactylus laurae, a junior synonym of L. angolensis. We also present the first confirmed record of L. lawrencei in the country, using both morphological and molecular data. The description of the new species and the revision of the taxonomic identity of the Angolan populations of the genus, raises the number of species occurring in the country to five. A key to the Angolan species is presented.
