Cysteochila idonea ? Drake 1956

Material examined: 1F, New Guinea, SE, bet. Brown River & Vanapa River, 16.XII.1964, L. & M. Gressitt, BPBM; 1F, New Britain, Gazelle Pen., Upper Warangoi, 1250m, 1–4.XII.1962, J. Sedlacek, BPBM.

Comments: The specimen from New Britain differs from the one from New Guinea by the larger carinae with larger areolae. However, they appear conspecific. This species is known from Kusai, the Solomon Islands, and New Guinea (NE, Busu River, E Lae; Wum, Upper Jimmi Valley; SE Darade Pl't'n, N Port Moresby, [Drake & Ruhoff 1965], and Madang, [Péricart 2000]).
