Description

According to Leviton (1964), the scalation includes 21 rows of dorsal scales at midbody, 170–178/175–184 ventral scales in males/females, 62–71/58–63 subcaudal scales in males/females, and 9–11 supralabial scales of which the 3rd is the largest. Toriba and Sawai (1990) give 167–179/172–184 ventral scales in males/females, 56–70/53–63 subcaudal scales in males/females, and 9–10/9–12 supralabial scales in males/females.[4]

Geographic range

Found on the Philippine islands of Agutayan, Batan, Camiguin, Catanduanes, Dinagat, Jolo, Leyte, Luzon, Mindanao, Mindoro, Negros, and Polillo. The type locality given is "Philippine Islands". Leviton (1964) proposed that this be restricted to "Luzon Island".[2]
