Papuacola Hampson
Type
species: lignicolor Hampson,
New Guinea.
Synonym: Leptotroga
Hampson
(type species costalis Moore)
syn.
n.
The two
genera brought into synonymy share the features of facies and male genitalia
described below. Papuacola has page priority in the same publication. The type
species of both occur in Borneo.
The
species are robust with deep wings, the forewing with a rounded angle central to
the distal margin. The facies is a ligneous fawn or brown, usually with finely
paler submarginals parallel to the margin or, on the forewing, sometimes with a
central angle also. On the costa is a pale-bordered, dark brown triangular or
trapezoidal mark between the postmedial or submarginal similar to that seen in
the Parallelia Hübner group of the Ophiusini, in Mecodina
Guenée
and allies, in Dordura Moore and in the Mocrendes Nye
group of Platyja
Hübner
(see also p. 14).
In the
male abdomen, the eighth sternite has a narrow transverse band of sclerotisation
basally that gives rise on each side to lateral bands of sclerotisation that
broaden distally to enclose a central triangular (gemina
Fabricius)
or circular (the type species) lacuna. The tergite has thicker sclerotisation
that forms a broad H-shape. The male genitalia show strong bilateral asymmetry
in lateral lobes to the tegumen and the distal processes, usually reflexed, of
the valves. The juxta consists of a pair of irregular, sclerotised bands in the
diaphragma. These may be homologous with the X-shaped structure seen in the
Ophiusini and other groups. The aedeagus is sinuous, narrow, with a distinctly
subbasal insertion of the ductus ejaculatorius.
The
female genitalia have a complex sterigma with an antevaginal plate similar to
that seen in the Parallelia group, but the ductus bursae is not sclerotised or
folded as in that group, and the sterigma extends back into the eighth segment.
All three included species occur in Borneo. The biology of one is known (see
below).
