Matanga Gen. n.

Type species: rubicunda Swinhoe.

The sole species in this genus has been placed in Chaetolopha Warren, together with a Himalayan species C. incurvata Moore. These are the only Oriental taxa in an otherwise Australasian genus, and morphologically unrelated to it or to each other (Holloway, 1986b). The forewing facies is somewhat similar to that of some Australasian Chaetolopha such as C. ornatipennis Warren, with contrasting ochreous dark brown and fawn bands on the forewing, the postmedial strongly dentate, though the medial dark brown zone in Matanga does not narrow so markedly towards the dorsum.

Characteristics of the genitalia are, however, very different. Chaetolopha males have a large hooked spine at the base of the valve costa, and a broad, rather excavate saccus. The uncus is vestigial. In Matanga the uncus is stronger, the valves simple, unornamented, and the saccus narrow, convex.

The female in Chaetolopha has the ovipositor lobes long, narrow, acute. The ovate bursa is set asymmetrically on a fluted ductus, and contains a long, slender, hornlike spine based in the basal bulge of the bursa. In Matanga the ovipositor lobes are more typical, the ductus very much longer, with a sclerotised zone where it joins the somewhat less asymmetric bursa: the signum is a small band of scobination longitudinally on the more expanded side of the bursa.

In C. incurvata the male genitalia are not dissimilar to those of Matanga, though the aedeagus is shorter, stouter and contains a mass of cornuti. The bursa of the female contains two large, thornlike spines centrally.
