Sibynophis triangularis Taylor & Elbel

Material examined. – O’Rang: FMNH 263023 , hilly evergreen forest, 12°20'05.8"N 107°02'26.2"E, 500 m elev., 12 Dec.2003 .

Remarks. – The single male agrees with Taylor and Elbel’s (1958) original description by having 10 supralabials, the tenth much the largest; the parietal in contact only with the upper of two postoculars, which is nearly square; a black triangular nuchal spot bordered by a white stripe continuous with the white supralabials; and a black spot on the outer edge of the ventrals.

The specimen was killed in the morning (0900 hrs.) by a local resident on a human trail in the forest.

This is the first report of the genus from Cambodia, and the first report of the species outside of the type locality in Chon Buri Province, southeastern Thailand, although Taylor (1965) provisionally referred literature records from Annam (central Vietnam) by Smith (1943) to this species.
