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).

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.

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.

We describe a new species of the genus Lygosoma from northeastern Cambodia based on a single voucher specimen col-lected from Veun Sai Proposed Protected Forest, Veun Sai District, Ratanakiri Province. 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.

Balantiocheilos ambusticauda sp. nov. is described from the Mekong and Chao Phraya river drainages in Indochina (mainland Southeast Asia). It can be distinguished from its only congener, B. melanopterus, in having a shorter snout (27.5–33.9% HL vs. 33.2–39.1), posteriorly directed grooves at rictus curved (vs. straight), and narrower black margins on the pelvic and anal fins (on distal third or less vs. on distal half or more). The possibility that B. ambusticauda is extinct is also discussed.

Schistura epixenos, new species, is described from the Nakai Plateau in Laos. It is distinguished from its congeners in Southeast Asia with a pattern of dark brown bars on a pale brown background by a combination of characters including, among others, a slender body, body with 13–17 bars reaching downwards to the level of the pectoral fin, a complete lateral line, scales present in the predorsal area, and the pelvic-fin origin below the dorsal-fin origin.

The genus Rapisma McLachlan, 1866 (montane lacewings) is a rare and little known group of the family Ithonidae (Insecta: Neuroptera). There have been 21 described species of Rapisma, and all of them are distributed from East Asia, South Asia and Southeast Asia. Here I report a new species of Rapisma from northwestern Yunnan, China, namely Rapisma weixiense sp. nov. The new species belongs to a group of Rapisma species with very short antennae.
