Diagnosis: One of the smaller species with thoracic and abdominal setae entirely black (Fig. 1 B); gena dusted silver to brownish pollinose, three dusted white lines on prescutum present, M 1 vein ending well past wing apex (Fig. 1 E). Females can usually be separated from the Palaearctic M. resplendens resplendens by the presence of 2 patches of short fine hair on dorsal surface of the fifth abdominal tergite (Fig. 6 A).
