Redescription

MEASUREMENTS. Body length: 3.0 mm. Wing length: 2.5 mm.

Male

Unknown.

Female (taken from type description in Zaitzev 1975).

Zaitzev had only 1 female specimen in bad condition at his disposal. But the specimen exhibits clear features that make it possible to distinguish it from all known taxa of the genus Parageron s. lat. and to describe it as a new species. Characterised by the yellow scutellum, yellow edges of mesonotum, yellow tibia and head. Body black, vertex, frons and face brownish-yellow, occiput black, vestiture of the head is white. Scape yellow; pedicel and postpedicel black, the latter segment is two times as long as the total length of the basal two segments. The palps are yellowish-grey, short, one-segmented, hardly protruding beyond the edge of mouth. Proboscis long, three times as long as the head. Thorax black, lateral margins of the mesonotum, and also some parts of the anepisternum and katepisternum yellow. Scutellum yellow. Hair on the thorax and the scutellum white. Fore coxae yellow, mid and hind coxae black. Femora black, apex of each femora, of the tibia and the basal tarsal segments yellow, the apical tarsal segments darkened. Wings hayline, all veins yellow. First basal cell longer than second basal cell (i.e., r-m distal to m-cu crossveins). Halteres white. The abdomen is black, the hind margins of all tergites with a yellow border, which occupies one third to one quarter the length of each tergite. Sternites black.

Remarks

Unfortunately, it was not possible to borrow the holotype of this species, nor could I visit the depository or obtain any photos. Zaitzev’s (1975) description is very brief, includes no figures, and does not discuss any characters that could definitively eliminate other genera within the Usiinae , particularly Apolysis . However, on the balance of probability, from the characters given, it probably does belong here. Further specimens and dissections of both sexes are much needed.
