Comment | Synonymy: “We follow Taylor (1965) and Morgan (1973) in considering this species to be valid and distinct from Sibynophis geminatus (Boie, 1826). Morgan (1973) concluded that both taxa occur sympatrically on Sumatra. He also considered the holotype of Sibynophis geminatus insularis Mertens, 1927 (Mertens, 1927: 240; type-locality. Forest at Sabang, Poloe Weh [= We Is., off north Sumatra]) to be an aberrant specimen of S. melanocephalus, although Morgan did not examine the specimen. According to Gaulke (1993: 151), the taxon Sibynophis geminatus insularis Mertens, 1927 (Mertens, 1927: 240) is valid. It should be regarded as Sibynophis melanocephalus insularis according to Gaulke (in press), whom we follow here.” (from David & Vogel 1996) |
Etymology | Named after Greek melano meaning black and cephalus meaning head, thus the black-headed species. |
