). Small to medium-sized, rather slender species with yellow-margined mesonotum, broad yellow fasciae on abdomen and very large and prominent male genitalia. Face yellow, with or without medial black vitta; eye bare; basoflagellomere large, twice as long as broad, tapering slightly to an acutely rounded apex. Mesonotum shining black with broad, well-defined, pale to bright yellow lateral vitta extending to postalar callus. Scutellum yellow, usually obscurely brownish on disc. Pleuron mostly shining black, except posterior anepisternum yellow on posterior half and katepisternum with a dorsal yellow macula. Dorsal and ventral katepisternal pile patches broadly separated posteriorly. Metasternum bare. Wing with microtrichia greatly reduced, absent from most of basal half and elsewhere very sparse and irregularly scattered. Abdomen elongate, parallel-sided or very narrowly oval, rather flattened, with a strong margin from middle of tergite 2 to the end of tergite 5. Tergite 2 with a pair of separate or narrowly confluent pale maculae; tergites 3 and 4 each with a rather broad, slightly arcuate yellow fascia separated from the base of each tergite. Very often, the black abdominal areas become reddish or yellow towards the abdominal apex, so the pattern is indistinct.
