'''''Trimeresurus flavomaculatus''''' also known as the '''Philippine pit viper'''<ref name=Gum04>Gumprecht A, Tillack F, [[Nikolai Liutsianovich Orlov|Orlov NL]], [[Ashok Captain|Captain A]], Ryabov S. 2004.

==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.<ref name=Gum04/>

==Geographic range== Found on the [[Philippines|Philippine]] islands of Agutayan, [[Batan Island|Batan]], [[Camiguin]], [[Catanduanes]], [[Dinagat Island|Dinagat]], [[Jolo]], [[Leyte]], [[Luzon]], [[Mindanao]], [[Mindoro]], [[Negros Island|Negros]], [[Panay Island|Panay]] and [[Polillo Island|Polillo]]. The [[Type locality (biology)|type locality]] given is "Philippine Islands". Leviton (1964) proposed that this be restricted to "Luzon Island".<ref name=McD99/>

==Taxonomy== Gumprecht (2001, 2002) relegates ''T. f. halieus'' to synonymy and elevates ''[[Trimeresurus mcgregori|T. f. mcgregori]]'' to a full species.<ref name=Gum04/>
