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 : 10

Zadbimyia holdenae sp. n.

Fig. 7 A–C

Diagnosis. This species is peculiar among Zadbimyia for the gonostylus having a protrusion subapicomedially, so the apical margin is angular rather than evenly rounded ( Fig. 7 A). The parameres have a pair of large, saber-shaped processes; the lateral shoulders are prolonged into narrow processes ( Fig. 7 C).

Other male characters. Body length 1.9 mm. Head. Eye narrowed ventrally, eye bridge 10–11 ommatidia long dorsally. Scape twice as long as pedicel. Antennae broken, maximum of 3 flagellomeres retained. Third flagellomere ( Fig. 7 B): neck length 0.4 × node length, neck completely covered with microtrichia. Palpus 3- segmented. Terminalia. Gonocoxites ( Fig. 7 A): ventral emargination U-shaped, sclerotized at base of U, antGA thick. Gonostylus slightly curved, pointed apically ( Fig. 7 A). Ejaculatory apodeme somewhat longer than parameres ( Fig. 7 C). Parameres elongate-subrectangular, apicomedial portion as long as wide, ending on same level with lateral shoulders ( Fig. 7 C).

Etymology. This species is named after Anna Holden, entomologist and manager of ZADBI in the initial phase of the project.

Holotype. Male, Costa Rica, San José province, Moravia, Zurquí de Moravia, 1600 m, 22 Oct. 2012, CDC light trap, ZADBI Project ( ZADBI #163, INBio #105272).
