Orgyia ruficeps Rothschild, 1920, J. fed. Malay St. Mus., 8
(3): 132, syn. n.
Laelia hyperbuana van Eecke, 1928, Zool. Meded. Leiden, 11:

Diagnosis. The male is dark uniform brown, slightly richer on the forewing. The
forewing discal area is faintly paler. The female may be that illustrated by
Schintlmeister (1994) as P. luisa ruficeps and resembles that of macrotera
Collenette (See Pantana melantera
Collenette), except the dark spots surrounding the cell end are
much darker, and surrounded by a somewhat paler zone.
Taxonomic note. The synonymy presented above is based on examination of type material.
The species is distinguished from the similar P. luisa Pagenstecher (Nias)
and P. adara Moore (Java) by the more square, less excavate distal
margin of the valve, the lack of a digitate process ventrally on the aedeagus,
and the presence of a finely spined process distally on the aedeagus vesica. P.
lymantricoides Felder (Ambon, S. Moluccas) has male genitalia as in adara,
and is represented by only the holotype. The locality is well to the east of
other records for the genus, and therefore this may represent an introduction or
a case of mislabelling.
Geographical range. Borneo, Sumatra.
Habitat preference. This is probably a lowland species, but material seen
is old and mostly lacking precise data. One is from Bidi in Sarawak
