Diagnosis. This is the only species of Zadbimyia with a furcate CuA (Fig. 3 B). The parameres have a pair of erect, posteriad-directed processes and a somewhat frayed apex (Fig. 11 C).

Other male characters. Body length 1.6 mm. Head. Eye strongly narrowed ventrally, eye bridge 8–9 ommatidia long dorsally. Scape length 1.5 × pedicel length. With 19–20 flagellomeres. Fourth flagellomere (Fig. 11 B): neck as long as node, with microtrichia basally. Clypeus asetose. Maxillary protuberance prolonged. Palpus with 2 elongate-cylindrical segments. Terminalia. Gonocoxites wider than in other Zadbimyia, ventral emargination large, broadly U-shaped, membranous at base of U (Fig. 11 A). Gonostylus evenly curved, evenly tapered on apical half, narrowly rounded apically (Fig. 11 A). Ejaculatory apodeme as long as parameres, ducts of accessory glands indistinct (Fig. 11 C). Parameres (Fig. 11 C): basal portion subtrapezoid, with small, strongly sclerotized apodemes; apicomedial portion narrow, 3 times longer than wide; processes arising at right angle from strongly sclerotized bases.
