Tortriciforma chloroplaga Hampson

Tortriciforma chloroplaga Hampson, 1905, Ann. Mag. nat. Hist. (7), 16: 587.

Tortriciforma chloroplaga Hampson; Holloway, 1976: 28.

Diagnosis

Sexual dimorphism is marked, males being much darker than females and with a dark, uniform reddish brown rather than a fawn, lightly banded hindwing (see Kobes, 1997, for illustration of the male). Both sexes have a characteristic forewing shape and a large green patch antemedially on the costa.

Taxonomic note

The material illustrated by Kobes (1997) appears also to be this species: it differs from viridipuncta in the broader green mark on the forewing costa and, in the male, a much redder colour to the hindwing. In the female genitalia the bursa is more convolute and with more definite, coarser spining. However, material from Java in RMNH, Leiden, appears to be closer in facies to viridipuncta.

Geographical range

Peninsular Malaysia, Borneo, Sumatra.

Habitat preference

All six Bornean records are from G. Kinabalu, from 1050m to 1930m. Only females have been taken.
