We describe Oligodon huahin sp. nov. from a bamboo forest locality on the road to Pala-U waterfall, Hua Hin District, Prachuap Khiri Khan Province, peninsular Thailand. It is characterized by a maximal known SVL of 553.7 mm; 6 maxillary teeth, the posterior two enlarged; 17-17-15 or 17-15-15 dorsal scale rows; 166–173 ventrals and 35–41 subcaudals in males; a single anal; deeply forked hemipenes lacking spines and papillae, extending in situ to the 14th subcaudal; faint to nearly indistinct vertebral, paravertebral and lateral stripes; no dorsal or supracaudal blotches or crossbars; and an uniformly ivory venter lacking subrectangular or squarish blotches. We also report the first finding of Oligodon deuvei in Thailand based on a specimen from Loei Province.

Etymology: The specific epithet is an invariable noun in honor of the administrative district where the type locality lies and of its charming main city Hua Hin. The following common names are given "Hua Hin Kukri Snake" (English), "Ngu Ngod Hua Hin" งูงอดหัวหิน or "Ngu Peekeaw Lai Hua Hin" งูปี่แก้วลายหัวหิน (Thai), "Oligodon de Hua Hin" (French) and "Hua Hin Kukrinatter" (German).

Habitat, behaviour and ecology: The habitat, behaviour and ecology of this species is poorly known, even though all specimens used for the species description were found in mixed bamboo forest area, the species is likely to inhabit several other types of habitats and elevations as well. Based on data for other members of the genus Oligodon, O. huahin is thought to be a oviparous (egg-laying) species. This species is nocturnal.

Oligodon huahin sp. nov. is added to a list of endemic reptile species we have recently described from the northern part of the Thai Peninsula, in Phetchaburi and Prachuap Khiri Khan provinces: Cnemaspis punctatonuchalis Grismer, Sumontha, Cota, Grismer, Wood, Pauwels & Kunya, 2010, Cyrtodactylus phetchaburiensis and C. samroiyot Pauwels & Sumontha, 2014 and Ptychozoon kaengkrachanense Sumontha, Pauwels, Kunya, Limlikhitaksorn, Ruksue, Taokratok, Ansermet & Chanhome, 2012. Far from being remote, their type-localities are within about four hours or less of easy drive from Bangkok metropolis, and illustrate how much still remains to be done to fully inventory the herpetofauna of Thailand. ....
