Etymology edit
The specific name, mcgregori, is in honor of Australian-American ornithologist Richard Crittenden McGregor (1871–1936), who collected the type specimen,[6] and survived its bite.[7]
Description edit
The scalation of T. mcgregori 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
T. mcgregori is 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]
Habitat edit
The preferred natural habitats of T. mcgregori are forest and shrubland, at altitudes from sea level to 800 m (2,600 ft), but it has also been found in agricultural areas.[1]
Taxonomy edit
T. mcgregori was originally described as a new species by E.H. Taylor in 1919.[8] It was considered to be a subspecies of T. flavomaculatus by Alan E. Leviton (1961).[2] It was re-elevated to a full species by Andreas Gumprecht (2001, 2002).[4]
