Diagnosis.
This is a large, rather lightly marked species, with an evenly curved submarginal row of spots on the forewing that are closely associated with striae expanding along the veins to the margin. The male lacks the strong fold in the cell characteristic of the next species, but the venation is otherwise similar. The male genitalia have the uncus small, the valves simple but asymmetric as illustrated. The bursa of the female is elongate and without strong spining.

Taxonomic notes. The original description of trichopteroides refers to a male, but the type (UM, Oxford) proves to be a female (see also Hampson, 1900). Hampson included the taxa neuropteroides Hampson (N.E. Himalaya) and nudarioides Butler as synonyms; these are distinct (stat. rev.), and perhaps closer to the next species.

Geographical range. Sumatra, Borneo.

Habitat preference. Most material is from the lower montane zone, the species being recorded from G. Mulu, G. Api, G. Dulit and Bukit Retak. It was taken also at 600m in lowland forest at Poring on the east of G. Kinabalu. It extends weakly down to 500m on G. Mulu, and was also taken singly in wet heath forest at 150m in the same area. The original material of trichopteroides is from Sarawak, probably taken in the lowlands.
