Eurychoria perata trajecta Prout; Holloway, 1976: 75.

Diagnosis

This species could be confused with Platycerota balia (See Platycerota balia). It is best distinguished by the yellowish tinge to the underside.

Taxonomic Notes

Originally described as a subspecies of perata Prout, this species has male genitalia that indicate it is best treated as a distinct species. There is a scobinate basal process on the valve costa that is lacking in perata. The furca consists of a pair of broad, sickle-like processes, whereas in perata two long, slender, straight processes flank a much shorter central pair.

Geographical Range

Borneo, Peninsular Malaysia.

Habitat Preference

The only Bornean records are from G. Kinabalu. It is infrequent in upper montane forest (1500-1930m).
