099C1A130D1657958E811488029A5552.taxon	distribution	Distribution. This species is known only from the type locality. The type series was collected from a karst formation that is part of the Tenasserim Mountain Range in Erawan National Park, Tha Kradan Subdistrict, Si Sawat District, Kanchanaburi Province, Thailand (Figs 1, 9).	en	Rujirawan, Attapol, Yodthong, Siriporn, Ampai, Natee, Termprayoon, Korkhwan, Aksornneam, Akrachai, Stuart, Bryan L., Aowphol, Anchalee (2022): A new rock gecko in the Cnemaspis siamensis group (Reptilia, Gekkonidae) from Kanchanaburi Province, western Thailand.

099C1A130D1657958E811488029A5552.taxon	etymology	Etymology. The species epithet auriventrali s is derived from aurum (L.) for gold and ventralis (L.) for venter in reference to the new species having distinct yellow colouration on all ventral surfaces of the head, body and tail in adult males. We propose " Erawan Rock Gecko " for the common English name and " จ ิ ้ งจกน ิ ้ วยาวเอราว ั ณ " (Jing Jok Niew Yao Erawan) for the common Thai name of the new species.	en	Rujirawan, Attapol, Yodthong, Siriporn, Ampai, Natee, Termprayoon, Korkhwan, Aksornneam, Akrachai, Stuart, Bryan L., Aowphol, Anchalee (2022): A new rock gecko in the Cnemaspis siamensis group (Reptilia, Gekkonidae) from Kanchanaburi Province, western Thailand.
