Sauris Guenée

Type species: hirudinata Guenée (spelt hirundinata in Fletcher (1979)).

Synonymy: Anisocolpia Warren (type species ignobilis Butler, N. India); Anthierax Warren (type species subfulva Warren, Solomons); Coptogonia Warren (type species turpipennis Warren, Batjan); Helminthoceras Warren (type species sinuaticornis Warren, New Guinea); Holorista Warren (type species proboscidaria Walker, Sri Lanka); Pseudoschista Warren (type species bicolor Warren, India); Remodes Guenée (type species abortivata Guenée = hirudinata).

Sauris is defined by a number of features: veins Rs and M1 are totally fused in the male hindwing; in the male genitalia the uncus is flanked by prominent, rather triangular socii bearing setae; the apex of the valve costa bears a characteristic lobe invested with hair-like setae (subapical process of Dugdale (1980)), and the valve apex itself usually bears a conspicuous brush of similar hair-setae (cucullus of Dugdale (1980)) that extends basally down the length of the interior of the valve (reduced in some species), and maybe retained in a central diaphragmal pouch; the ventral margin of the valve is expanded, with fine transverse pleats over the expanded part; the female ductus seminalis joins the genitalia opposite the opening of the appendix bursae. In many species there are small setal patches laterally on the male fourth sternite (e.g. Figs 313, 319). Another common feature (seen in the majority of Bornean species) is the pleating of the male hindwing apex into several lobes, usually invested with denser, darker scales: this is usually associated with a marginal cleft on the forewing just anterior to the tornus. The male hind-tibia and tarsus are sometimes tufted or the latter inflated.

Sauris is much more species-rich than related genera, extending from the Indian subregion to the Pacific as far east as Niue I. Dugdale noted a dozen species in Australia, and there are at least thirteen in Borneo.

The larva of the type species is described below. Singh (1953) noted the genus to have a finely granulate larval skin and unusual fringed spinnerets. The host range (Singh, 1953; Murphy, 1990; Holloway, 1996c; Bell MS; unpublished IIE records) is wide: Cassine (Celastracea); Excoecaria (Euphorbiaceae); Alseodaphne, Cinnamomum (Lauraceae); Dendrophthoe, Loranthus (Loranthaceae); Lagerstroemia (Lythraceae); Syzygium (Myrtaceae); Sapindus (Sapindaceae).
