Zadbimyia talamanca sp. n.

Fig. 20 A–C

Diagnosis. In Z. talamanca, the parameres have three pairs of small, sclerotized processes, no lateral shoulders, and the apicomedial portion 3–4 times longer than wide (Fig. 20 C). In Z. zurqui, a species having paramere processes very similar to that in Z. talamanca, the lateral shoulders are pronounced and the apicomedial portion is much shorter (see Fig. 21 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 23 flagellomeres. Fourth flagellomere (Fig. 20 B): neck length 0.4 × node length. Palpus 4-segmented. Terminalia. Gonocoxites (Fig. 20 A): ventral emargination small, broadly subrectangular, vaguely contoured at base. Gonostylus narrower basally than subapically, strongly curved on apical half, tapered toward apex, apex directed dorsad (Fig. 20 A). Ejaculatory apodeme shorter than parameres (Fig. 20 C). Parameres (Fig. 20 C): basal portion broad-subtriangular, apicomedial portion slightly constricted at mid-length.
