Description.
MALE. Black; ocellar triangle shining; frontalia brownish ventrally, lunule brown; gena browntinged; mesoscutum weakly shining coppery, abdomen brilliantly metallic-coppery. Wing hyaline, calypter with margin and fringe yellow.
Frons nearly 1.5 times as wide as eye, slightly converging ventrally; parafrontalia linearly projecting above eye in profile;

S6 four times as long as S5, about 4/5 as long as wide, with very shallow emargination posteriorly. Epandrium with surstylus projected posterodistally and incurved, bearing three spines at base and 20–22 spines in three to four rows on distal projection; cercus 2/3 as high as epandrium, slightly broadened at middle (about 1/3 as wide as epandrium). Hypandrium 350 µm long, with basal apodeme 1/3 as long as sidearm. Phallapodeme 560 µm long; phallus 380 µm long, basiphallic sclerites bent ventrally near distal end, forming a square in ventral view, mesophallus with membranous tube weakly curled, distiphallus slightly wider than mesophallus, with distal tube short; ejaculatory apodeme 280 µm long, blade expanded roundly, 220 µm wide.

Remarks

.
in having similar coloration and large ocellar triangle, but it is smaller, and has a less shining mesoscutum and a characteristic phallus as described above.
Etymology
. The specific name refers to the curly appendage (Latin:
cirratus
+
appendicula
) of the mesophallus.
