Pangrapta
albiseriata Hampson
Pangrapta
albiseriata Hampson, 1926, Descr. Gen. Spec. Noctuinae,
p. 567.
Diagnosis.
The forewing is characterised by a paler grey-brown, broad, transverse medial
band between the reniform and the antemedial, and by a virtually uniform distal
third of the wing, apart from a few darker submarginal flecks. The hindwing has
a series of white lunules and dentate marks of various sizes associated with the
submarginal; this series is broken by dark brown breaking through from basal to
it and extending obliquely back to the margin at about M3.
Taxonomic
note. The male genitalia have an uncus typical of the genus and
valves as in the previous two species. The aedeagus vesica is more globular and
has two groups of robust, blunt cornuti and one solitary more spine-like one.
The female has numerous setae on the eighth segment, and (S. James, pers.
comm.)
the apex of the abdomen was invested with fuzzy black wool that was lost in
dissection. The ductus is short, unsclerotised, and the corpus bursae is
transversely ovate, almost mushroom-like. The ductus seminalis arises from one
side.
Geographical
range. Borneo, Peninsular Malaysia, Sumatra, Thailand (VK).
Habitat
preference. The species is infrequent in lowland forest and has not been
recorded above 300m. S.J. Willott (unpublished data) recorded it almost entirely
and in some numbers from the understorey of lowland forests in the vicinity of
the Danum Valley Field Centre, though Chey (1994) recorded it in some frequency
in lowland softwood plantations.
