Fig. 4 A–D

Diagnosis. This is the only species of Zadbimyia whose parameres have one pair of large, apically curved, movable processes, smooth lateral shoulders, and a seemingly two-pointed apex (Fig. 4 B). See Z. browni (Fig. 5 B) and Z. artborkenti (Fig. 6 D) for two species with similar paramere processes.

Other male characters. Body length 2.0 mm. Head. Eye slightly narrowed ventrally, eye bridge 10–11 ommatidia long dorsally. Scape length 1.8 × pedicel length. With 20 flagellomeres. Fourth flagellomere (Fig. 4 D): neck length 0.4 × node length, neck completely covered with microtrichia. Palpus with 2–3 segments, if 2- segmented apical segment markedly elongated. Thorax. Setae on both anepisternum and anepimeron sparse. Legs. Claws with tiny ancillary tooth subapically. Terminalia. Gonocoxites (Fig. 4 C): ventral emargination large, broadly V-shaped, antGA thick. Gonostylus large in relation to gonocoxite, evenly curved, excavated dorsomedially (Fig. 4 C). Ejaculatory apodeme as long as parameres, slightly broadened toward apex, ducts of accessory glands indistinct (Fig. 4 B).

Etymology. The name costaricensis is a Latin adjective referring to the occurrence of this species in Costa Rica.
