Article Reference A new Four-clawed Gecko from limestone hills in Lopburi Province, central Thailand (Squamata, Gekkonidae: Gehyra)
We describe Gehyra wongchan sp. nov. from Tham Khao Chan (Khao Chan Cave), Tha Luang District, and Wat Khao Wong, Kok Samrong District, in Lopburi Province, central Thailand. The new species differs from all currently recognized Gehyra by the following combination of morphological characters and dorsal color pattern: maximal known snout–vent length of 52.4 mm, 8–10 supralabials, 76–80 dorsal and 48–50 ventral scale rows around midbody, absence of skin folds on limbs, 17 or 18 preanofemoral pores in males in a continuous series extending to mid-length of femur (pores absent in females), tail not- to moderately widened behind vent in adults, a single row of widened subcaudals, digits and toes unwebbed, 7 or 8 divided subdigital lamellae on 4th toe, and a dorsal pattern with white spots as large or larger than adjacent crescentic black markings on a beige to light-brown background.

Article Reference Cranial osteology of Hypoptophis (Aparallactinae: Atractaspididae: Caenophidia), with a discussion on the evolution of its fossorial adaptations
Fossoriality evolved early in snakes, and has left its signature on the cranial morphology of many extinct Mesozoic and early Caenozoic forms. Knowledge of the cranial osteology of extant snakes is indispensable for associating the crania of extinct lineages with a particular mode of life; this applies to fossorial taxa as well. In the present work, we provide a detailed description of the cranium of Hypoptophis wilsonii, a member of the subfamily Aparallactinae, using micro-computed tomography (CT). This is also the first thorough micro-CT-based description of any snake assigned to this African subfamily of predominantly mildly venomous, fossorial, and elusive snakes. The cranium of Hypoptophis is adapted for a fossorial lifestyle, with increased consolidation of skull bones. Aparallactines show a tendency toward reduction of maxillary length by bringing the rear fangs forward. This development attains its pinnacle in the sister subfamily Atractaspidinae, in which the rear fang has become the “front fang” by a loss of the part of the maxilla lying ahead of the fang. These dentitional changes likely reflect adaptation to subdue prey in snug burrows. An endocast of the inner ear of Hypoptophis shows that this genus has the inner ear typical of fossorial snakes, with a large, globular sacculus. A phylogenetic analysis based on morphology recovers Hypoptophis as a sister taxon to Aparallactus. We also discuss the implications of our observations on the burrowing origin hypothesis of snakes.

Article Reference Philothamnus ruandae Loveridge, 1951. Rwandan Green Snake. Reproduction.
We provide new data on the reproduction of the Rwandan Green Snake Philothamnus ruandae (Squamata : Colubridae) based on high resolution x-ray computed tomography of five adult pregnant females, including the holotype and three paratypes. The smallest gravid female has a snout-vent length of 552 mm, and clutch size varies from 4 to 12.

Article Reference A new karst-dwelling, colorful pitviper (Viperidae: Trimeresurus) from northern Peninsular Thailand
We describe a colorful and distinctively patterned, karst-dwelling pitviper, Trimeresurus kuiburi sp. nov., from the isolated, coastal massif of Khao Sam Roi Yot in Kui Buri District, Prachuap Khiri Khan Province, in northern Peninsular Thailand. The new species, member of the ‘Cryptelytrops group’ sensu Malhotra & Thorpe (2004) and morphologically and genetically allied to Trimeresurus kanburiensis and T. venustus, differs from all pitviper taxa by a combination of red/purple bands on a green dorsum; a white concave suborbital stripe in males (straight and less visible in females); white, spaced vertebral dots in males (absent in females); pale green belly lacking dark dots or stripe on the lateral sides of the ventrals; partially fused first supralabial and nasal scale; 19 dorsal scale rows at midbody; 164–171 ventrals; 63–65 subcaudals in males, 51–53 in females; maximal known SVL of 451 mm; and long, papillose hemipenes.
