Heterostegane tritocampsis classeyi

7-8mm. In facies this race resembles typical tritocampsis and ssp. macrographa from Sulawesi. It is pale dull orange with only the medials and submarginals prominent. It is distinguished by features of the male genitalia. The typical race has the arms of the furca large, basad; the ventral portion of the valve bears two large, reflexed spines and points adjacent to each other; the spines on the triangular ventral portion of the valve are small, but costally and well short of the apex. In ssp. classeyi the furca is as in the typical race but the ventral portion of the valve is more strap-like with a spine subbasally on the costa and another opposite just in from the centre of the ventral margin. A specimen from Luzon (slide 15654) is similar to classeyi but the second spine is more central on the valve.

Holotype . SARAWAK: Kuching, Semengok, 3-9.11.1976 (E. W. Classey) BM geometrid slide 15629.

Paratypes: 5, 1 as holotype; 1, 1 SARAWAK: Gunung Mulu Nat. Park, R.G.S Exped. 1977-8 (J.D. Holloway et al.) Site 17 nr Long Melinau, 50m and Site 16, Long Pala (Base) 70m.

Geographical range. India, Sri Lanka; Borneo, Java, Philippines; Sulawesi (ssp. macrographa)

Habitat preference. Bornean material is from lowland forest.

Biology. Singh (1953) described the larva of the typical race, giving extensive details of chaetotaxy. The material was preserved in spirits so there are no data on fresh colouration.

The host-plants were Acacia and Mimosa.
