VII. Ocinara Walker, 1856 ( FIGURE 12 )

Ocinara Walker, 1856 , List Specimens lepid. Insects Colln. Br. Mus. 7: 1768. Type species: Ocinara dilectula Walker, 1856 , by monotypy.

Diagnosis. The genus is diagnosed by the presence of a furculum in the male, which is a modification of the 8th tergite into a rectangular structure with lateral adpressed spines arising from an anterior 'frame'. In female genitalia, there is a large and scobinate signum in bursa, a large rounded lamella antevaginalis and a smaller lamella postvaginalis distinct from the 8th tergite, and distinctive lateral lobes on the membrane between these structures and the ovipositor lobes.

Distribution. Oriental and Palearctic Regions.

Remarks. The larvae of the Ocinara group were described by Mell (1958). They mostly resembled those of Gunda in having swellings on segments A2 and A5 and an extensile horn on A8. The horn could be flexed and extruded to terminate in a white apiculus. In contrast to the eggs of Trilocha varians , which are flattened, slightly rectangular discs, those of Ocinara are laid in long rows, with the shorter edges flattened and touching. The rows may curve but are not angled, and can be laid side-by-side but are separate. Pupation takes place in a yellow, semiovoid silken cocoon, which is usually attached to the surface of a leaf. The larval host plants of the group consist of Ficus , Artocarpus and Streblus (Moraceae) (Dierl, 1978; Mell, 1958; Roepke, 1924). The larva of the type species has been described as green with a horn on the 8th abdominal segment (Dierl, 1978), feeding on Ficus (Moraceae) . The genus is most diverse in Sundaland, with only one species extending into the Indian Subregion, this being the only species recorded from China (Map 7).
