New Species from the Mekong Delta

Cnemaspis Biocellata
Discovered in 2008, this gecko is a native of the isolated karst peaks of the Nakawan mountain range, which spans the border between Thailand and Malaysia. Among the most brightly colored of the newly discovered species, it has five yellow, butterfly-shaped spots that extend from its shoulders to the base of its tail. Males are yellow-and-gray; females are light brown. The species is generally nocturnal but can be seen during the daytime in the shade afforded by rocks and tree trunks.
