Didigua
viridifusa
Kobes
Didigua viridifusa Kobes, 1997: 150.
Diagnosis. The forewings have a straw- or bone-coloured ground with light
speckling and typical Didigua fasciation in brown with a slight greenish
tinge. There is also some blackish suffusion, and the submarginal row of spots
is interrupted by ground colour at one-third and two-thirds. There are two
discal dots arranged longitudinally and roughly centrally in the medial zone,
though the more basal one may be weak.
Taxonomic note. The species illustrated as
viridipicta
Hampson by Kobes (1997) may be a variant of viridifusa. Typical
viridipicta (Himalaya) has the more irregular submarginal with a more
complete row of spots. The genitalia do not match those illustrated by Kobes,
the valves being slightly expanded towards the apex, the tegumen broader
distally and the aedeagus vesica with the distal diverticula terminating in
clusters of spines and a row of three or four small, robust cornuti at the base
of the ductus ejaculatorius. The abdomen has massive pouches containing hair
pencils on each of tergites 5-7, a feature not mentioned by Kobes for either
species, and distinct from the situation in viridifusa where there is a
single large pouch on the seventh tergite; thus both viridipicta and
viridifusa may be best placed with the
Lasionotella
group.
Geographical range. Sumatra, Borneo.
Habitat preference. The paratype female noted by Kobes is from disturbed
lowland forest at 30-60m in the Labi area of Brunei. The species is infrequent
in lowland forest and can persist in secondary forest.
