Dipterygina
vagivitta Walker comb. n.
Dypterygia vagivitta
Walker, 1862, J. Linn. Soc. Lond. (Zool.), 6:185, three
syntypes in U.M. Oxford, one of which is the next species. The male (1/3)
hereby designated LECTOTYPE and so
labelled.
Dypterygia vagivitta Walker; Holloway, 1976: 10.
Diagnosis.
This and the
next species are very similar but the next has a paler major step mark on the
forewing dorsum, the basal margin of which is more strongly bilobed and oblique
rather than perpendicular to the dorsum. The shape and ornamentation of the
aedeagus vesica differ, with dorsipallens having a weaker and more distal
patch of spines; the finger-like process of the valve apex is shorter and
broader in dorsipallens.
Taxonomic
note. The subspecies obscurior Warren from Christmas I. in the Indian
Ocean probably represents a distinct species.
Geographical
range. Borneo.
Habitat
preference. The
species is rare, found from the lowlands to about 1200m.
