CLARISSA OBSCURA sp. nov. 
Colour black ; pale brown are the labrum, front margin of clypeus, the 
front legs (except base of femur, trochanters and coxa) the middle and hind 
tibiae apically as well as the tarsal segments at their joints. Wings slightly 
infuscate ; stigma and venation black, except basal half of costa which is 
brownish. 
Length 6 mm. ; fore wing 5-5 mm. ; antenna 4 mm. though the Brisbane 
specimen is 8 mm. ; forewing 6-2 mm. ; antenna 4-5 mm. 
Puncturation on head dense, shallow and irregular, on nota of thorax in 
the form of regular round scattered punctures with shining smooth spaces 
between ; the punctures are thicker at the sides of the lobes of the mesonotum 
and the scutellum, but sparser in the middle of the mesonotal lobes ; on pleurae 
and sterna the puncturation is irregular and shallow ; on the abdomen the 
dorsum is transversely rugulose. 
Head : length of clypeus and labrum together equal to about the breadth 
of the clypeus ; clypeus emarginate in the middle of the front margin ; malar 
space in length about two-thirds the diameter of an ocellus ; antennae 14-15 
segmented, not club-shaped, increasing in breadth slightly until about segment 
6 or 7, and then tapering slightly ; funicle and pedicel very short ; pedicel 
about twice as broad as long ; segments 4 and onwards being each much 
broader apically than basally, the basal breadth being about two-thirds of the 
apical breadth ; median fovea as a deep rounded depression ; vertical furrows 
clearly defined. Legs with hind basitarsus equal to two following tarsal 
segments ; inner hind tibial spur in Brisbane specimen equals about five-sixths 
length of basitarsus, in other specimens almost equals basitarsus in length. 
Abdomen with hypopygium set up erect, and entire on hind margin.
