Five new species of geckos are described from Sri Lanka by morphological comparison and morphometric analysis leading to review the genus Cnemaspis in the country. The type series of these species were identified from following localities: C. alwisi and C. kumarasinghei from the intermediate zone, C. retigalensis from the dry zone, C. molligodai from the lowland wet zone and C. samanalensis from the mountain region of the wet zone in the country. The high degree of endemicity (90%) shown by Cnemaspis in Sri Lanka could be attributed to geographical isolation. In addition, the taxonomic issue of C. jerdonii scalpensis is discussed and the species C. scalpensis is errected.

Examination of the Dendrelaphis bifrenalis populations on Sri Lanka showed that there are two populations that are morphologically different from each other. One population is distributed only in the wet zone forests (hereafter treated as wet zone population), while the other population occurs widely in the dry zone and intermediate zones (hereafter dry zone population). The type series of D. bifrenalis consist of 3 specimens from which the specimen representing the dry zone population was chosen as lectotype, and the wet zone population is described here as a new species. It clearly differs from D. bifrenalis by having a shorter snout, orbit diameter 103–114% of eye–nostril length (vs 77–95%), and larger eye, orbit diameter 21–23% of head length (vs 17–20%). Furthermore it differs by having a temporal stripe stopping just beyond the neck (vs continues behind neck), the absence of black transverse dorsolateral bars on the anterior 1/4th of body (vs prominent), a narrow and pointed snout (vs broad and flat), a divided nasal (vs single), and a ventrolateral stripe continuing up to the tail (vs stopping at the level of the anal plate). This morphological differentiation is supported by the divergence in the mitochondrial NADH dehydrogenase subunit 4 (ND4) region separating clearly with the divergence of 1.70±0.35%. Also, here we resurrect D. effrenis (Werner, 1909) as a valid species, and D. sinharajensis as a junior synonym of it. The holotype of D. sinharajensis was chosen as the neotype of D. effrenis to stabilize nomenclature, and to make it an objective synonym. The third and fourth known specimens of this rare species are reported. A key of the species of the genus Dendrelaphis in Sri Lanka is provided.

Taxonomic revisions are the most reliable pathway in unfolding new species to the world. During such a revision of the genus Lagenandra in Sri Lankan, we came across two new species: Lagenandra kalugalensis and Lagenandra srilankensis from the Wet Zone of Sri Lanka. The two new species were studied in detail and compared with the morphology of the other species described in the genus, and based on field collected data conservation assessments were performed. A detailed description for the two new species and an updated taxonomic key to the Sri Lankan Lagenandra is presented here for easy identification. Recognizing two new endemic members enhances the number of Sri Lankan species of Lagenandra to eleven and global to nineteen. According to the IUCN red data category guidelines, L. kalugalensis qualifies for Critically Endangered category under Criterion B1ab (ii,iii,v) + B2ab (ii,iii,v) while L. srilankensis qualifies for Critically Endangered category under B1ab (iii, iv) + C2 (a) (i, ii). Hence, immediate conservation measures are imperative.

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 C. podihuna and C. molligodai 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.

AbstractAll Oriental and Australasian/Oceanic species of Pegadomyia are re-examined. A detailed study of the generic characters shows that Pegadomyia actually contains two easily diagnosed genera: Pegadomyia Kertész, 1916 and Pseudopegadomyia gen. n. Pegadomyia now includes the type species P. pruinosa Kertész, 1916 (occurring in Malaysia, Taiwan and Thailand) and three new species: P. ceylonica sp.n. (from Sri Lanka), P. nana sp.n. (from Laos) and P. nasuta sp.n. (from Malaysia). Pseudopegadomyia contains Ps. jamesi sp.n. (based on a type series from the Philippines) and two species originally belonging to Pegadomyia: Ps. glabra (Bezzi, 1928), comb.n. (Fiji Is.) and Ps. nuda (James, 1948), comb.n. (Australasian Region and Philippine Is.). Figures of the diagnostic characters of all treated species are included. Identification keys and a map showing the distribution of all species of both genera are presented.

A New Species

A new species of Rhinophis, Rhinophis erangaviraji sp. nov. is described, the tenth species of the genus known from Sri Lanka. The new species is readily distinguished from all other congeners by its colour pattern and scalation. Morphometric analysis supports the distinction of the new species from the superficially similar R. blythii. The new species is known only from the Rakwana massif, where it has been collected in shady areas, within loose soil.

The subtribe Cylindromorphoidina Cobos, 1979, the only representative of tribe Aphanisticini in the Neotropical region, is currently composed of two genera, Eurynodes Théry, 1934 and Cylindromorphoides Kerremans, 1903. The genus Taphroceroides Hespenheide, 2007, originally proposed in Cylindromorphoidina, is currently placed in Brachyina (tribe Tracheini). A detailed morphological comparison of Taphroceroides species with members of Eurynodes and Cylindromorphoides shows similarities that strongly support their transference back to Cylindromorphoidina. A new morphological definition and classification of Cylindromorphoidina is presented along with the description of new species in the three genera: Eurynodes gemmatus sp. nov., E. capillatus sp. nov., Cylindromorphoides ferrugifrons sp. nov., Taphroceroides brunneus sp. nov., and T. brasiliensis sp. nov. Photographs and comments on the type series of previously described species are provided. New biological data and possible association of Cylindromorphoidina species with Bromeliaceae are reported. Finally, a distribution map is provided for all species of Cylindromorphoidina.

Vicia mingyueshanensis, a new species from the Mingyue Mountain Region of western Jiangxi, China, is described and illustrated. It is a perennial climbing liana that always links to riparian woods. A morphological comparison indicated that the new species is closely similar to Vicia taipaica K. T. Fu and Vicia dichroantha Diels; however, it differs from the other two species by several salient characters, such as plant indumentum, stipule shape, corolla colour, bractlet shape and calyx shape. Photographs, a preliminary conservation assessment, table of morphological characters and distribution map comparing this new species to two morphologically-similar species are also provided.
