Gariga Walker

Type species: argentilinea Walker, Borneo.

Synonym: Ca
mptozada Hampson (type species mirabilis Swinhoe, Burma, India, Bali, Sumatra) syn. n.

The type speci
es of these genera share features of general build, facies and genitalia, and they are therefore brought into synonymy. The scales of the thorax are directed forward anteriorly in a narrow double peak. The forewings are rather narrow, somewhat oval in shape, fawn with extensive brown suffusion. The antemedial and postmedial are irregular, transverse, obscure, either of the pale ground colour or silvered. The tornal area is often darker submarginally. The hindwings are brown above; in argentilinea they are paler and finely fasciated below. The forewing venation is reduced in the radial sector as in Dumatha Walker and Homophlebia Warren, the branching system of three veins being of the form (X (X,X)). The hindwing venation is trifine rather than quadrifine; Homophlebia is similar but Dumatha is quadrifine with M3 and CuA1 stalked.

In the male abdomen, there are basal tymbal organs of the more robust chloephorine type, identical in argentilinea and mirabilis and similar to those of the other two genera. In the genitalia the uncus is long, slender, apically tapering. The valves are narrow, distally bilobed, the more dorsal lobe being much broader and deeper. The saccus is well developed. The aedeagus is narrow, the vesica small and also very narrow.

In the female (mirabilis) the ductus bursae is long and slender, joining the corpus bursae in a short zone of sclerotisation at the point of separation of the pyriform bursa and a massive, ovate, but flimsy appendix bursae. The sterigma is rather extensive, finely rugose, with an arched ridge anteriorly.

The biology of Camptozada mirabilis was recorded in S. India by Bell (MS). The larva is cylindrical. The head is orange with four black dots (setal bases) across the upper part. The body is a dark slaty grey sometimes with a reddish dorsal line. There is a yellow subspiracular band over the abdominal segments adjacent to white patches below each spiracle that are conjoined with black ones above each spiracle. The venter is a paler grey.

The larvae feed on young leaves, resting on the under-surface or a petiole. Pupation is in a similar position within a cocoon of yellow silk, blotched or streaked with brown or black, a broadly truncated semi-ovoid.

The host plant recorded was Grewia (Tiliaceae). This is also noted by Bell for Homophlebia bilinea Swinhoe, and there is also a record (IIE, unpublished) of Microcos in the same family for Camptozada.
