Zadbimyia anniae, Jaschhof, Mathias & Jaschhof, Catrin, 2014

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 : 18-19

Zadbimyia anniae sp. n.

Figs 2 C, 16A–D

Diagnosis. This is the only species of Zadbimyia with distinctly acuminate gonostyli ( Fig. 16 A). The parameres have two pairs of short, sharp processes, of which the ventral are almost straight and pointing distolaterad, and the dorsal are slightly curved and pointing laterad ( Fig. 16 D).

Other male characters. Body length 1.4 mm. Head ( Fig. 2 C). Eye strongly narrowed ventrally, eye bridge 7–8 ommatidia long dorsally. Scape twice as long as pedicel. With 26–27 flagellomeres. Fourth flagellomere ( Fig. 16 B): neck length 0.4 × node length, circumfilum extremely pale, barely visible, microtrichia on apical half of node sparse. Palpus 3-segmented. Terminalia. Gonocoxites ( Fig. 16 C): ventral emargination small, broadly V-shaped, with small notch at base of V. Gonostylus slender, evenly, strongly curved, excavated medially, strongly tapered toward apex ( Fig. 16 A). Ejaculatory apodeme as long as parameres ( Fig. 16 D). Parameres ( Fig. 16 D): basal portion broad-subtriangular, apicomedial portion elongate, 3 times longer than wide, slightly constricted at mid-length.

Etymology. This species is named after Annia Picado, an INBio-trained parataxonomist with many years of experience, who applies her expertise to the slide-mounting of small dipterans including cecidomyiids collected by ZADBI.

Types. Holotype. Male, Costa Rica, San José province, Moravia, Zurquí de Moravia, 1600 m, 9–19 Oct. 2012, Malaise trap, ZADBI Project (ZADBI #177, INBio #105286). Paratype. Male, same locality as the holotype, 23 Sep. 2012, hand-collected, ZADBI Project (ZADBI #64, INBio #105081).
