Chora Walker
Type species: repandens
Walker, Borneo.
Synonym: Careades
Bethune-Baker (type species
sanguinea Bethune-Baker, New Guinea).
This genus has facies
similar to
Carea in the female, but shows strong sexual dimorphism, the male having the
postmedial running very much more obliquely from the tornus to basal to the
midpoint of the costa. The male also has the dorsal zone of the hindwing with a
dense coating of longer scales.
The male abdomen of
the type species is typical of the Carea group but is also characterised
by interiorly directed combs of hair-setae from the lateral margins of each
sternite. The genitalia have the valve rather elongate, the costal process
erect, not associated with a marginal lobe. The aedeagus vesica is globular,
with a single cornutus.
The female has a
narrow, unsclerotised ductus, and a pyriform bursa with a distal, rather
irregular and short signum of the golf tee type.
More easterly taxa of the
genus have not been dissected, but its definition rests on the sexual dimorphism
described in the first paragraph. The type species is the most westerly
representative of a moderately diverse Australasian typical genus. Poole (1989)
listed the species in Careades, including repandens as a new
combination, though he placed Chora as a synonym of Carea. This
anomaly was rectified by Kobes (1997), though Poole’s system was followed by
Nielsen et al. (1996).
