Ocinara Walker

Type species: dilectula Walker.

This and related genera were revised by Dierl (1978),
who illustrated male and female genitalia as far as possible for all species. The group as a whole has venation as in Fig. 4. The moths are usually white, cream, pink or red; sexual dimorphism is slight. The forewings are not falcate and are usually marked with fine fasciae that are darkly punctate on the veins. The component genera are defined on genitalic characters but in most males the saccus is long, well developed, the uncus is not bifid in the majority, and the eighth abdominal sclerites are strongly modified. The valves are usually reduced to small, peglike structures. The females often have weak dorsal accessory lobes to the ovipositor lobes.

Bell (MS) described larvae of the Ocinara group. They resemble mostly those of Gunda in having swellings on segments A2 and A5 and an extensile horn on A8. The horn can be flexed and extruded to terminate in a white apiculus.


The eggs (?Trilocha varians) are a slightly rectangular disc, half as high as long and larger than broad, top and bottom flat. The eggs are laid in long, touching rows, the shorter, touching ends flattened. The rows may curve but are not angled and may be laid side by side but separate.


Pupation is usually in a semiovoid, yellow, silken cocoon, with silk outworks, usually attached to the surface of a leaf.

Host-plants noted for the whole group (Dierl; Bell; Roepke (1924)) are species of Ficus, Artocarpus and Streblus (Moraceae).

Ocinara is defined by the presence of a furculum in the male, a modification of the eighth tergite into a rectangular structure with lateral, adpressed spines, either one or two on each side, arising from an anterior 'frame'. In the female there is a large, scobinate signum in the bursa, a large, rather rounded lamella antevaginalis and a smaller lamella postvaginalis distinct from the eighth tergite, and distinctive lateral lobes on the membrane between these structures and the ovipositor lobes.

The larva of the type species is described as green with a horn on segment A8 (Dierl), feeding on Ficus (Moraceae).


The genus is most diverse in Sundaland, only one species extending into the Indian Subregion. There are two species on Sulawesi, one endemic, one shared with the Philippines.
