Zadbimyia artborkenti sp. n.

Figs 2 B, 6A–D

Diagnosis. Zadbimyia artborkenti is another species with a single pair of apically curved paramere processes (Fig.

6D) (see Z. costaricensis, Fig. 4 B, and Z. browni, Fig. 5 B). Unlike similar species, the ejaculatory apodeme in Z. artborkenti has a broad-lanceolate, often seemingly three-pointed apex (Fig. 6 D), and the gonostyli are abruptly, not smoothly, curved apically (Fig. 6 A–B).

Other male characters. Body length 1.3 mm. Head (Fig. 2 B). Eye slightly narrowed ventrally, eye bridge 10–11 ommatidia long dorsally. Scape twice as long as pedicel. With 16–18 flagellomeres. Fourth flagellomere (Fig. 6 C): neck length 0.4 × node length, neck on basal half with microtrichia, circumfilum irregularly sinuous, not looped. Palpus 4-segmented. Legs. Claws with tiny ancillary tooth subapically. Terminalia. Posterior margin of tergite IX concave medially. Gonocoxites (Fig. 6 A): ventral emargination small, broadly U-shaped, with subtriangular sclerotization at base of U. Gonostylus parallel-sided on basal two thirds, then suddenly curved at almost right angle, tapered toward apex, excavated dorsomedially (Fig. 6 A–B). Ejaculatory apodeme as long as parameres, basal portion weakly sclerotized, varying in shape (Fig. 6 D). Parameres: basal portion subrectangular, apicomedial portion elongate, 3 times longer than wide; processes usually single-pointed (Fig. 6 D), in one specimen with small ancillary point.

Etymology. This species is named after Art Borkent, a world expert on the systematics of various families of Culicomorpha and co-principle investigator of the ZADBI project.
