Racotis Moore

Type species: boarmiaria Guenée.

Species in this genus all have a typically irregularly mottled facies, rufous brown or brown on fawn, with the fasciae and discal markings obscure. Only the postmedial is relatively distinct, crenulate, but irregular. On the underside the discal spots and the zone distal to the postmedials are dark brown, the rest of the wings pale fawn.

The male antennae are usually strongly ciliate over the basal two thirds and occasionally weakly bipectinate. There is a strong, rather triangular fovea. The setal comb on the third sternite is present. In the male genitalia the uncus is bifid in most species (entire in R. inconclusa Walker and allies) and the valve is distally rather narrow, consisting of only the cucullus towards the apex. A generic feature is a prominent, interiorly directed spur subbasally on the sacculus. The vesica in most species bears a clump of slender spines at the apex of a distal diverticulum.

In the female genitalia there is a narrow triangular zone of sclerotisation ventrally between the ovipositor lobes. The ductus is unsclerotised though there is a transverse lamella antevaginalis at the ostium. The bursa is elongated, fluted and sclerotised over all but a short apical sector. The signum is absent.

The larva is relatively short, robust, green or brownish green, usually with a paler lateral line (Sato, 1984a; Sugi, 1987).

Host-plant records are mostly from Lauraceae, one from Annonaceae. The life history of R. inconclusa is described below. The Japanese R. petrosa Butler has been recorded from Benzoin, Lindera and Parabenzoin (Lauraceae) (Sato & Nakajima, 1975; Sato, 1984a).

The genus is most diverse in the Oriental tropics; a few species occur in Africa and Madagascar. There are three in Borneo.
