|Comment||Similar species: Cnemaspis vandeventeri is most similar to C. chanardi, C. kamolnorranathi, C. roticanai, and C. siamensis of Peninsular Thailand and was considered conspecific with C. chanardi, and C. siamensis by Smith (1925, 1930, 1935) and (Taylor 1963).|
Distribution: See map in Grismer 2020: 548 (Fig. 1).
|Etymology||The specific epithet vandeventeri, a masculine name in the genitive case, is a patronym honoring Mr. Ryan J. VanDeventer of the Department of Biology at La Sierra University, Riverside, California. “Mr. VanDeventer’s passion for, and commitment to the study of biology has been a continual source of enlightenment and inspiration. His heroic efforts to keep La Sierra University’s herpetology laboratory and its occupants up and running smoothly for the last 16 years goes beyond description.”|
