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.
