Diagnosis.
This species and the next two are very similar and both show great variation in
the extent of development of the discal black patch. Whereas pudens
is
a pale, somewhat pinkish brown, the other two are greyer with a pale mauve to
violet tint that is frequently most conspicuous in zigzag submarginals on fore-
and hindwings, tending towards lactipex Hampson in this character. The forewing
antemedial in the next species makes a right-angle with the dorsum on its distal
side, whereas in pudens this angle is slightly obtuse. At the
costal end of the antemedial, the curvature basad occurs closer to the costa in
the next two species.
Taxonomic
note. Poole (1989) placed both the senior and junior homonyms of hypopyroides
Walker
as synonyms of vespertilio,
but it is clear from the material labelled as types of these that only the
junior homonym, Spirama hypopyroides Walker
(1863), should have this status. Enmonodia hypopyroides Walker
(1858) is a synonym of pudens as listed above. The male genitalia of pudens
are
very similar to those of vespertilio except the uncus is longer and the lobes on the valve
sacculi are narrower, particularly on the right side. H.
villicosta Prout
(Philippines: Mindanao) is probably related to pudens,
having similar male secondary sexual characters on the underside, but with
facies more as in pallidigera
except
the distal margins are diffusely darker and the forewing discal spot is small
and oval.
Geographical
range. Japan,
India, Andamans, Sundaland, Sulawesi.
Habitat
preference. The species is infrequent from the lowlands, including
disturbed and coastal areas, to 1618m. Chey (1994) found the species to be
common in plantations of Acacia mangium and Paraserianthes
falcataria in the lowlands of Sabah, perhaps indicating that the larva feeds
on those trees (see below).
Biology.
Robinson et
al.
(2001) recorded Paraserianthes falcataria (Leguminosae) as a host plant.
