<strong>A new species of the genus Calotes Cuvier, 1817 (Squamata: Agamidae) from southern Vietnam</strong>

We describe a new species of the agamid genus Calotes Cuvier, 1817 from southern Vietnam, which is most similar to Calotes mystaceus Duméril & Bibron, 1837, but can be distinguished from the latter and its other congeners by genetic and morphological differences. We discuss the current distribution of the new species and its sister species C. mystaceus in Mainland Southeast Asia.

A new species of the dicroglossid frog genus Limnonectes is described from recent and historical museum specimens collected in central and southern Laos and northeastern Thailand. Limnonectessavansp. nov. has males that bear a caruncle on top of the head, and most closely resembles L.dabanus from adjacent southern Vietnam and eastern Cambodia. However, the new species is readily distinguished from L.dabanus, and all other caruncle-bearing species of Limnonectes in mainland Southeast Asia, by its adult and larval morphology, mitochondrial DNA, and advertisement call. Its description brings the total number of caruncle-bearing species of Limnonectes to six.

A New Species

A new species of the Cyrtodactylus irregularis group is described from Ninh Thuan Province, southern Vietnam based on molecular divergence and morphological differences. Cyrtodactylus orlovi sp. nov. is distinguished from the remaining Indochinese bent-toed geckos by having the unique combination of the following characters: size medium (SVL 61.0–77.7 mm); dorsal tubercles in 16–20 irregular rows; 36–39 ventral scale rows; precloacal pores absent in females, 5 or 6 in males, in a continuous row; femoral pores absent; 3–8 enlarged femoral scales; postcloacal spurs 1 or 2; lamellae under toe IV 16–19; a continuous neckband; a highly irregular transverse banded dorsal pattern; the absence of transversely enlarged median subcaudal scales. In phylogenetic analyses, the new species was revealed to be the sister taxon to a clade consisting of Cyrtodactylus cattienensis and the most recently described species from Vietnam, C. chungi, with 12.1–12.4% and 11.7 % pairwise genetic divergence from the two species, respectively, based on a fragment of the mitochondrial COI gene.

Kryptopterus geminus, a new species of silurid catfish is described from the Bang Pakong, Mekong, Mae Khlong and Chao Phraya River drainages in mainland Southeast Asia. Kryptopterus geminus, together with K. cryptopterus, can be distinguished from congeners by the dorsal profile lacking a nuchal concavity and short maxillary barbels extending to the base of the pectoral fin. Kryptopterus geminus can be further distinguished from K. cryptopterus in having a narrower head (9.5– 12.0% SL vs. 12.2–14.2), longer anal fin (62.2–72.7% SL vs. 57.2–62.9) and snout (39.5–45.3% HL vs. 35.1–39.8), and more laterally-placed eyes (only ventral half, vs. ventral two-thirds, of the orbital margin visible when the head is viewed ventrally).

Abstract—Isodon hsiwenii, a new species from Yunnan in Southwest China, is here described and illustrated. In order to clarify the phylogenetic placement of the new species within Isodon, Bayesian and maximum likelihood analyses based on two nuclear ribosomal DNA regions and four plastid DNA regions for 71 Asian Isodon species were conducted. The results indicate that I. hsiwenii is a member of the largest and poorly resolved Clade III, as sister species of I. hirtellus. Isodon hsiwenii can be distinguished from I. hirtellus by various morphological differences.

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.

A new species of the genus Camellia L. (Theaceae) from Southern Vietnam is described and illustrated under the name Camellia proensis. Morphological differences between C. proensis and closely related species in the genus Camellia L. (sect. Piquetia) were identified. C. proensis is easily distinguishable from C. honbaensis, C. piquetiana and C. longii by the yellow flowers; from C. dalatensis by the glabrous twigs and leaves; from C. dongnaiensis by light yellow flowers; from C. sonthaiensis by mature fruit flat-globose, 4.0–5.5 cm tall and 8.5–10.0 cm wide. Ecological environment and distribution were also provided for this new species. The images and type specimens of this species were processed and stored in Vietnam (holotype, isotypes, DLU).

A New Species

Cylindrophis is a genus of secretive, semi-fossorial, non-venomous snakes comprising 14 species, characterized by a generally cylindrical body, uniform scales (with barely enlarged ventrals), and vestiges of pelvic and limb bones, the latter terminating in a claw lateral to the vent. We reconstructed a concatenated molecular phylogeny of seven taxa of Cylindrophis taxa based on one nuclear (R35) and two mitochondrial (16S, ND2) genes. Analyses recovered the Sri Lankan endemic C. maculatus as sister to all other sampled Cylindrophis. The mainland Southeast Asian species C. burmanus and C. jodiae form successive sister lineages to a monophyletic Wallacean island group containing C. boulengeri, C. isolepis, and C. yamdena. We also describe a new species of Cylindrophis, morphologically similar to C. burmanus, from Kachin State in northern Myanmar. Cylindrophis slowinskii sp. nov. is distinguished from all congeners by the following combination of characters: 19 dorsal scale rows at midbody, 216–220 ventrals, eight subcaudals, a dark venter with > 60 very narrow diffuse pale blotches, and a pale bar running along the posterior border of the prefrontals. In our phylogeny, the new species is strongly supported as the sister species of C. burmanus. It is the 15th currently recognised species in the genus, and the fourth from mainland Southeast Asia.

Lygosoma veunsaiensis sp. nov.is differentiated from all congeners occurring in mainland Southeast Asia by the combination of the following characters:outer ear opening absent; supranasals distinct and separated from each other by frontonasal; supranasals not fused withnasals; midbody scales in 22 rows; fontoparietals paired; five supralabials; a light stripe present on outer edge of the dor-sum; and a dark dorsolateral stripe present, from behind the eye to the tail. A key to the Southeast Asian mainland species of Lygoma is provided.
