“ Trigonocephalus wagleri var. sumatrenis Gray, 1849 ”

Trigonocephalus wagleri , var. Sumatrenis Gray, 1849: 9 . Name appearing in the synonymy of Trimesurus subannulatus Gray, 1842 , as a name provided or written on a label by the Leyden Museum. —Type locality. Sumatra. — Holotype. BMNH 1.2.6.e (female).

Comments. As for Trigonocephalus wagleri, var. celebensis, Gray (1849) cited this taxon in the list of available material of Trimesurus subannulatus Gray, 1842 . It thus should also be considered a synonym of Trimesurus subannulatus .

Gray used the spelling “ sumatrenis ”, and not sumatrensis as cited by McDiarmid et al. (1999).

The combination Trigonocephalus wagleri , var. Sumatrenis was mentioned for specimen “e.”. The catalogue of the BMNH includes only one specimen from Sumatra donated by the Leyden Museum, which should be the specimen cited by Gray (1849).

However, we could not locate any instance in which this combination was regarded as valid before 1961. Therefore, according to Art. 11.6.1 of the Code, this name, although resulting from a valid description, was not made available. According to Dubois (2000), it is here considered to be an anoplonym.

Status. An unavailable name; subjective synonym of Tropidolaemus wagleri ( Boie, 1827) .
