Zadbimyia zumbadoi sp. n.

Fig. 9 A–E

Diagnosis. Zadbimyia zumbadoi resembles Z. minima in respect to the parameres (Figs 9 E, 8C). Unlike Z. minima, the lateral eye bridge in Z. zumbadoi shows no signs of reduction; the flagellomere nodes are barrel-shaped rather than subglobular (see Fig. 9 C versus Fig. 8 B); the gonostylus is longer and not so strongly tapered apically (Fig. 9 A versus Fig. 8 A); and the gonocoxal emargination has a pigmented collar (Fig. 9 D).

Other male characters. Body length 1.5 mm. Head. Eye bridge 7–8 ommatidia long dorsally. Scape length 1.5 × pedicel length. Antennae broken, maximum of 16 flagellomeres retained. Fourth flagellomere (Fig. 9 C): neck length 0.4 × node length, neck with microtrichia basally. Palpus 4-segmented, longer than length of head. Terminalia. Posterior margin of tergite IX concave medially (Fig. 9 B). Gonocoxites (Fig. 9 D): ventral emargination large, broadly U-shaped. Gonostylus slender, evenly curved, excavated dorsomedially, slightly tapered toward apex (Fig. 9 A, D). Ejaculatory apodeme longer than parameres, with short sclerotized point beyond accessory gland ducts (Fig. 9 D, apex of apodeme not shown in Fig. 9 E). Parameres (Fig. 9 E): basal portion subtrapezoid, apicomedial portion narrow, slightly longer than wide, shoulders pronounced, lobe-like, a pair of small, hooked, dorsad-directed processes.

Etymology. This species is named after Manuel Zumbado, dipterist and head of the Biodiversity Inventory Unit at INBio.
