Trichosea Grote

Type species: ludifica Linnaeus (Europe).

The genus contains a number of species with striking black and white forewings, mostly more finely fasciated than the Bornean species (see Kobes (in press)), and grey, yellow and white hindwings. Apart from the European type species the genus is restricted to the Oriental tropics and subtropics, mainly from montane localities in the tropics. The male genitalia are of a type found in other noctuid subfamilies (e.g. Acronictinae, Agaristinae) with a simple harpe, slender valves with a coronate distal margin and a setose peniculus; there is a single corema on sternite 8.

Gardner (1946) described the larva of the Indian species, champa Moore, and grouped it with species in the genus Acronicta. It has a distinctly hairy appearance with paired hirsute protruberances on the thorax and sub-terminally. It is black, the dorsal surface ornamented with reddish brown streaks and symmetrically arranged white spots on each abdominal segment, the latter most intense on the first abdominal segment. The spiracles are white and between them on the flanks from the metathorax backwards are white trapezoid patches invested with white hairs. The European species has a larva of similar appearance but with (in a dried larva), three buff dorsal lines and further such lines arranged in a series of ‘half-asterisks’ along the flanks, grading ventrally into a generally buff, rather stippled zone; the hairs are longer than in champa, less adpressed, and buff.

Gardner gave the host-plants of champa as Prunus and Pyrus (Rosaceae). The European species is recorded from Sorbus (Kirby 1903). The genus may therefore be restricted to Rosaceae; the genus Prunus extends to New Guinea and Queensland.
