Borbacha Moore
Type species: pardaria Guenée.
Synonym: Borbachodes Warren (type species pardalis Felder
& Rogenhofer, Moluccas, ?Sulawesi) syn. n.
Sundanian Borbacha species were reviewed by Holloway (1982).
Though the facies resembles that of Parasynegia, with pinkish
grey reticulation and fasciation on a pale yellow ground, other morphological
features are distinctive, and the genus can only be loosely associated with the
Baptini and not at all with the major group with peg-like setae.
The forewing discal spots are usually black. The broadest fasciae are
the hindwing intermedial and the forewing postmedial. These are contiguous,
oblique in a spread insect, the line often being continued by a bar from the
angle of the forewing postmedial to the margin. This angle is obtuse, the
postmedial continuing anteriorly from it irregularly to the costa.
The retinaculum in the male is elongate, apically scrolled. The forewing
has a distinctive fovea, the only occurrence of this feature in the tribe and of
a form unique in the Ennominae (Fig 1). The base of Al is swollen and curved to
be slightly concave anteriorly. On the underside there is an irregular
triangular depression just anterior to this concavity, bordered on the other
side by a carinate ridge that is close to the posterior of the cell.

The male antennae are strongly unipectinate, those of the female
moderately so. The pectinations taper away to nothing at about two thirds. In
the male genitalia the valve setation is consistent with placement in the
Baptini, but there are no processes from the costa or peg-like setae. There are
weak coremata. The valve resembles more that of Lomographa. The uncus is
long and socii are present. The gnathus is vestigial. The aedeagus vesica is
tubular, bearing one small cornutus centrally, sometimes two.
The female genitalia have the ostium broad, membranous, funnel-like,
leading into a narrow, sclerotised, laterally scrolled ductus. The bursa is
pyriform, with a large irregularly rhomboidal signum arising from an elliptical
base. There is a long, slender appendix bursae arising from the centre of the
bursa.
The type species of Borbachodes possesses all the male diagnostic
features (males only are known) noted above, with no unique ones of its own
apart from small size. The genus is therefore sunk to Borbacha.
No biological data have been located. The genus is restricted to the Indo
Australian tropics.
