Corgatha oligochroa Prout comb. n.

Enispa oligochroa Prout, 1926, Sarawak Mus. J., 3: 218.

Diagnosis

The ground colour of the wings is a pale ochreous yellow but this is heavily and uniformly suffused with medium grey except for the forewing costa and fine, irregular and indistinct fasciation elsewhere.

Taxonomic note

The facies is similar to that of some Corgatha, and the male genitalia resemble those of C. atrimargo except the saccular process of the valve is more sinuous. It is therefore transferred to that genus.

Geographical range

Borneo.

Habitat preference

The holotype is from about 2000m on G. Murud in Sarawak. Seven specimens were taken more recently in upper montane forest at 1780m and 1790m on G. Mulu.
