Zadbimyia elviae, 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 : 21-22

Zadbimyia elviae sp. n.

Fig. 19 A–D

Diagnosis. This is the only species of Zadbimyia whose ejaculatory apodeme is as long as the gonocoxites, or even slightly longer ( Fig. 19 C). As another notable character, the ejaculatory apodeme has a long, strongly sclerotized portion beyond the accessory gland ducts.

Other male characters. Body length 1.5 mm. Head. Eye strongly narrowed ventrally, eye bridge 8–9 ommatidia long dorsally. Scape twice as long as pedicel. With 24 flagellomeres, nodes subglobular. Fourth flagellomere ( Fig. 19 A): neck length 0.4 × node length, neck with microtrichia basally. Palpus 4-segmented. Terminalia. Posterior margin of tergite IX concave medially. Gonocoxites ( Fig. 19 C): setae sparse ventromedially, ventral emargination shallow, broadly U-shaped. Gonostylus narrower basally than subapically, evenly curved, broadly rounded apically ( Fig. 19 C). Parameres ( Fig. 19 B, D): basal portion subtrapezoid, apicomedial portion twice as long as wide, 3 pairs of sclerotized processes situated behind one another, subequal in size, curved to various degrees, movable and thus varying in orientation (see Fig. 19 B versus Fig. 19 D).

Etymology. This species is named after Elvia Zumbado, a long-time parataxonomist and employee at INBio, who assists in sorting to family ZADBI’s enormous amounts of collected specimens.

Types. Holotype. Male, Costa Rica, San José province, Moravia, Zurquí de Moravia, 1600 m, 20 Oct. 2012, CDC light trap, ZADBI Project (ZADBI #171, INBio #105280). Paratypes. 1 male, same locality as the holotype, 24 Sep. 2012, CDC light trap, ZADBI Project (ZADBI #53, INBio #105066); 1 male, same locality, 19 Oct. 2012, CDC light trap, ZADBI Project (ZADBI #151, INBio #105260).
