Dunira Moore

Type species: scitula Walker.

Eclipsea Hampson (type species luna Hampson, India), syn. n.; Sarcopteron Hampson (type species punctimargo Hampson, Sri Lanka), syn. n.

The species are similar in facies to those of Olulis but have the forewing pattern continued onto the hindwing more consistently. The genus is best distinguished on features of the abdomen as described below. In Eclipsea the facies is generally similar to that of typical Dunira except the forewing apex has a dark patch with a circular inner boundary. The features of the male genitalia are exactly as in Dunira, however, as are those of Sarcopteron Hampson (illustrated by Sugi (1979)), so these genera are brought into synonymy.

In the male abdomen, the eighth tergite is posteriorly rounded and has well separated apodemes anteriorly. The sternite is strongly bilobed posteriorly, and lacks anteriorly directed apodemes, though the anterior corners of the sclerite are produced laterally. The genitalia have a number of unusual features: a sclerite shaped like an inverted ‘V’ in the tegumen ventral to the slender uncus; valves with a costal spur, a central ampulla, and the extensive, fine, dorsally directed hair-setation over the apicodorsal lobe and along the ventral margin (the valve is weakly trilobed apically). There is virtually no saccus. In the Eclipsea species and to some extent in obliquilinea Hampson, the basal apodemes of the abdomen are robust, with angular thickening to the sclerite lateral margins.

In the female genitalia the ostium is set within the eighth segment, where the apodemes are short, and is ventrally cleft in the type species. There is a convolute, sclerotised chamber between the ductus and the rather spherical bursa. The bursa contains some weak but extensive scobination. These features may indicate some affinity with the Saroba group of genera (p. 337), so the genus is associated tentatively with this group. However, unlike in other members of the Saroba group, phragma lobes are absent from the anterior of the second abdominal tergite.

Most species are Oriental but some extend east to Seram and New Guinea. The two species from
Sarcopteron (Sugi, 1979; Poole, 1989) are D. punctimargo Hampson comb. n. (Sri Lanka, Taiwan) and D. fasciata Wileman & South comb. rev. (Japan).
