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 : 13-14

Zadbimyia viquezi sp. n.

Fig. 10 A–C

Diagnosis. Zadbimyia viquezi is unmistakable by the parameres having a pair of evenly crescent-shaped processes ( Fig. 10 C). Also, this is the only species of Zadbimyia known to bear a seta on preepisternum 2—an exceptional case in Porricondylinae .

Other male characters. Body length 1.4 mm. Head. Eye slightly narrowed ventrally, eye bridge 7–8 ommatidia long dorsally. Scape twice as long as pedicel. Antennae broken, maximum of 16 flagellomeres retained. Fourth flagellomere ( Fig. 10 A): neck length 0.4 × node length, neck with microtrichia basally. Palpus 4-segmented.

Terminalia. Gonocoxites long, setae sparse ventromedially, ventral emargination broadly V-shaped, with dense short setae laterally ( Fig. 10 B). Gonostylus slender, strongly curved on apical third, excavated dorsomedially, strongly tapered toward apex ( Fig. 10 B). Ejaculatory apodeme longer than parameres ( Fig. 10 C). Parameres ( Fig. 10 C): basal portion elongate-subtrapezoid, apicomedial portion twice as long as wide, shoulders smooth.

Etymology. This species is named after Carlos Viquez, arachnologist and head of the Arthropod Collection at INBio.

Holotype. Male, Costa Rica, San José province, Moravia, Zurquí de Moravia, 1600 m, 5–9 Aug. 2013, handcollected, ZADBI Project ( ZADBI #1071, INBio #107598).
