Schnell (ZMB NO. 116). Etymology: From Latin, reduncus meaning curved or hooked backward which refers to the shape of caudomedian projection of superior volsella, and the epithet of the most closely related species, and New Latin oides , referring to the likeness of form.

Sternapodme broad horizontal band. IVo simple, small, blunt, slightly dilated at the apex. AR = 0.75. BR 1–3 = 1.4, 1.2, 1.4. AnP 67 µm long with 13–19 setae. Gs with slight bent distally, CD developed, long and low. HR = 1.6. Male (n = 5). Total length = 3.1mm Coloration of slide-mounted specimen : Head and thorax dark brown, abdomen golden-brown, halter light brown with dorsolaterals darker, and wing yellowish brown. Head.
