Dunira Moore
Type
species: scitula Walker.
Synonyms: 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).
