Euhampsonia Dyar

Euhampsonia roepkei sp. n

43-53 mm, montane specimens tending to be smaller than lowland ones. The forewings are a very much deeper, richer brown than in the Himalayan niveiceps Walker. The main differences are in the male genitalia where the uncus and gnathal processes are larger, the former flattened horizontally rather than vertically and apically bifid. The aedeagus tapers strongly apically and the deciduous spicules in the vesica are much finer. The valves are longer, slender, the central spine longer and the ventral margin is sclerotised rather than membranous and corrugate.

Euhampsonia roepkei (paratype)

SARAWAK: Gunong Mulu Nat. Park, R.G.S. Exped. (J.D. Holloway et al) BM 1978-206, Site 5, Camp 4, Mulu, 1780 m, 451463, [upper montane forest, low facies], BM notodontid slide 962.

Paratype. 1 with general data as holotype but Site 4, January, Camp 4, Mulu, 1790 m, 452463 [upper montane (moss) forest, tall facies].

W. Roepke was intending to publish a description of this species under the name sumatrana just prior to his death; it is therefore dedicated to him.

Taxonomic notes. Shachihoka formosana
Matsumura (Taiwan), as illustrated by Sugi (1979), is obviously very closely related to niveiceps. The genus Shachihoka Matsumura is therefore a synonym of Euhampsonia Dyar, syn. n., if E. gigantea Druce is also treated as congeneric.

It is likely that there is a complex of species in the Himalaya and China as a dark Khasis male (slide 961) had genitalia different from those illustrated for niveiceps by Kiriakoff (1968); there is a multiple spine at the aedeagus apex and an uncus similar to that illustrated for formosana Matsumura.

Geographical range. Borneo, Sumatra, Peninsular Malaysia.

Habitat preference. The type material is from upper montane forest on G. Mulu but a specimen was also recorded from lower montane forest on the same transect. Two males have also been taken at about 300 m in hill dipterocarp forest, Ulu Temburong, Brunei.

Biology. Sevastopulo (1938-1947 (3)) has described the larva of niveiceps. The triangular head is bluish-green with white markings. The body is mainly white apart from green thoracic segments and seven subdorsal green stripes posteriorly to the thorax. The 11th segment (7th abdominal) is humped. The spiracles are set in a yellow line and are ringed with red and white. The legs are shaded green. There is a large anal flap, edged reddish brown.

The pupa is in a slight cocoon in leaf litter in captivity.

The host-plant recorded was Quercus (Fagaceae).
