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 : 17-18

Zadbimyia marcoi sp. n.

Fig. 15 A–C

Diagnosis. In Z. marcoi the gonocoxites have an unusually large, evenly U-shaped ventral emargination ( Fig. 15 A), and the ejaculatory apodeme has a short sclerotized point beyond the accessory gland ducts ( Fig. 15 B).

Other male characters. Body length 1.6 mm. Head. Eye narrowed ventrally, eye bridge 10–11 ommatidia long dorsally. Scape twice as long as pedicel. With 18–21 flagellomeres. Fourth flagellomere ( Fig. 15 C): neck length 0.4 × node length, neck with microtrichia basally, circumfilum unusually strongly sinuous. Palpus 4- segmented. Terminalia. Gonocoxites ( Fig. 15 A): ventral emargination with pigmented collar. Gonostylus slender, evenly curved ( Fig. 15 A). Ejaculatory apodeme longer than parameres ( Fig. 15 B). Parameres ( Fig. 15 B): basal portion subrectangular, apical portion short, tulip-shaped, 1 pair of processes each with 4–6 points, lateral shoulders (largely hidden behind the processes) pronounced.

Etymology. This species is named after Marco Moraga, an INBio-trained parataxonomist who has performed both field and laboratory work for the ZADBI project.
