Species Distribution and Climate Change

A new species of Lycodon, L. ferroni, from Samar Island, central-eastern Philippines, is described. This species is most similar to L. dumerili, from which it differs in having: 10 supralabials (IV-VI entering eye) instead of 9 (IV-V); dorsals reducing to 15 at the level of ventral 119 instead of at ventrals 131–145; body and tail with dark annuii instead of dark cross-bands. Lycodon contains about 25 species, 8 of which are endemic to the Philippines: alcalai (Batan Island, Batan Group), bibonius (Camiguin Island, Babuyan Group), chrysoprateros (Dalupiri Island, Babuyan Group), dumerili (Basilan, Mindanao), ferroni (Samar), muelleri (Batan, Luzon, Mindoro, Polillo), solivagus (Luzon), and tessellatus (Luzon); the 2 non-endemic species, L. subcinctus (SE Asia) and especially L. aulicus (S Asia), seem to be anthropophilous and likely to have reached the Philippines through human agency. An extensive review strongly suggests that L. striatus nordicus Deranivagala 1955 is a synonym of L. striatus bicolor (Nikolsky 1903) (new svnonvmv).
