Differs structurally from an undescribed Japanese species in having the second recurrent nearer the apex of the areolet, the first tergite broader, the hind tarsal claws of the female with a basal lobe, and female subgenital plate with a large median basal membranous area. Male: Black. Face, frons, cheek, clypeus, mouth parts, scape and pedicel except above, lower part of propleurum and adjacent part of pronotum, large hind corner of pronotum, tegula, subtegular ridge, coxae, trochanters, and front and middle femora and tibiae, whitish; flagellum fuscous, a little paler beneath, its basal few segments whitish beneath; front tarsus whitish, its apex brownish; middle basitarsus whitish, its apex brown; second to fourth segments of middle tarsus brown; fifth segment of middle tarsus brown, its basal half stramineous; hind femur pale fulvous; hind tibia white, with a narrow subbasal and a broader apical fuscous band; hind tarsus infuscate, the basal half of its first segment whitish and the basal half of its last segment light brown; second to sixth tergites narrowly stramineous on apex, the base of second tergite sometimes also narrowly stramineous.
