Zadbimyia talamanca, 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 : 22-23

Zadbimyia talamanca sp. n.

Fig. 20 A–C

Diagnosis. In Z. talamanca , the parameres have three pairs of small, sclerotized processes, no lateral shoulders, and the apicomedial portion 3–4 times longer than wide ( Fig. 20 C). In Z. zurqui , a species having paramere processes very similar to that in Z. talamanca , the lateral shoulders are pronounced and the apicomedial portion is much shorter (see Fig. 21 C).

Other male characters. Body length 1.6 mm. Head. Eye strongly narrowed ventrally, eye bridge 8–9 ommatidia long dorsally. Scape length 1.5 × pedicel length. With 23 flagellomeres. Fourth flagellomere ( Fig. 20 B): neck length 0.4 × node length. Palpus 4-segmented. Terminalia. Gonocoxites ( Fig. 20 A): ventral emargination small, broadly subrectangular, vaguely contoured at base. Gonostylus narrower basally than subapically, strongly curved on apical half, tapered toward apex, apex directed dorsad ( Fig. 20 A). Ejaculatory apodeme shorter than parameres ( Fig. 20 C). Parameres ( Fig. 20 C): basal portion broad-subtriangular, apicomedial portion slightly constricted at mid-length.

Etymology. The name, a noun in apposition, refers to the Talamanca Mountains where the type locality of this species is located.
