TAXONOMY

Acosmeryx shervillii Boisduval, [1875], in: Boisduval & Guenée, Hist. nat. Insectes (Spec. gén. Lépid. Hétérocères), 1: 217. Type locality: [India, West Bengal,] Darjeeling [Darling].

Synonym. Acosmeryx cinerea Butler, 1875.

Synonym. Acosmeryx miskini brooksi Clark, 1922.

Synonym. Acosmeryx socrates obliqua Dupont, 1941.

Note. Acosmeryx shervillii and Acosmeryx pseudonaga Butler, 1881 were until recently treated as forms of the same species. The latter was synonymized with Acosmeryx ancea [sic] by Hampson, [1893], Fauna Brit. India 1: 82; then with Acosmeryx socrates by Rothschild & Jordan, 1903, Novit. zool. 9 (suppl.): 533. Synonymized with Acosmeryx shervillii as a form by Holloway, 1987, Moths of Borneo 3: 149. Erroneously treated as a synonym of Acosmeryx socrates by Bridges, 1993, Cat. Fam. Gen. Spec. Sphingidae of the World: VIII. 1. Reinstated as a species by Haruta, 1994, Tinea 14 (suppl. 1): 156. Resynonymized with Acosmeryx shervillii by Inoue et al., [1996], Moths of Thailand 2: 68. Reinstated as a species by Hogenes & Treadaway, 1998, Nachr. entomol. Ver. Apollo Suppl. 17: 66. The two are now regarded as two distinct species.
