Jaschhof, Mathias & Jaschhof, Catrin, 2014, Zadbimyia, a new genus of asynaptine Porricondylinae (Diptera: Cecidomyiidae) with twenty-two new species from the cloud forest of Costa Rica, Zootaxa 3866 (1), pp. 1-29 : 8

Zadbimyia costaricensis sp. n.

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.
