♂: Face in frontal view slightly divergent from level of antennal insertion to lower mouth edge, shining with very slight pollinosity, lower part somewhat protruded (Fig. 9A). Facial knob rounded, shining, moderately protruded. Parafacia rather narrow, in the upper part approximately 1/2 the width of basoflagellomere, in lower part slightly narrowed. Parafacia shining, or with slight pollinosity on upper part. Frons slightly swollen, shining, with predominantly yellow and a few black pile. Frontal angle ≈ 90°. Lunula black. Antennal pits separated. Vertical triangle with black and a few yellow pile. Eye-contiguity slightly shorter than length of frons without lunula. Basoflagellomere small, brownish, arista rather long, almost bare (or with very short pile) (Fig. 9B). Scutum shining, rather densely punctated, all covered with erect yellow and black pile of even length, pile becoming slightly longer towards scutellum. Postalar callus with few black bristles. Scutellum with only yellow pile, margin without longer black bristles. Anepisternum and katepisternum with slight pollinosity, with yellow long pile. Ventral and dorsal pile patches on katepisternum narrowly connected posteriorly. Halter yellow. Wing with all cross-veins infuscated, completely covered with microtrichia. R4 + 5 of wing not curved.

Mesofemur posteriorly with white pile, metafemur anteroventrally and -dorsally with long white pile, and ventrally with shorter (stronger) black pile. Abdomen shining laterally, mid parts of tergites I–III with pollinosity. Tergites with yellow erect pile, longer on the sides and shorter medially. Sternite I pollinose, other sternites shining, pile yellow, erect. Hypopygium as on Fig. 9E–G. ♀: Face and parafacia as in the male. Frons coarsely punctated, with white erect pile, and also with black erect pile on posterior part (Fig. 9D). Parafacia < 1/2 the width of basoflagellomere. Basoflagellomere reddish (Fig. 9C).
