Common names: McGregor's pit viper.[4]

Trimeresurus flavomaculatus mcgregori is a venomous pitviper subspecies[5] endemic to the Philippines.


The subspecific name, mcgregori, is in honor of Richard Crittenden McGregor (1871-1936), who collected the type specimen,[6] and survived its bite.[7]


The scalation includes 21 (23) rows of dorsal scales at midbody, 170-172/173-178 (or 169-172/168-178) ventral scales in males/females, 62-66/58-60 (or 63-69/56-62) subcaudal scales in males/females, and 10-11 supralabial scales.[4]

Geographic range[edit]

Found in the Philippines on the Batanes Islands. The type locality given is "Batan Island, Batanes Group, (lying between Luzon and Formosa)" (Philippine Islands).[2]
