Tetraneuromyia wilksae View in CoL sp. n.

( Fig. 7 View FIGURE 7 A–D)

Diagnosis. Tetraneuromyia wilksae , in every respect a typical representative of the genus Tetraneuromyia ( Jaschhof & Jaschhof 2013) , is close to T. moldaviensis (Spungis) as indicated by male genital morphology. In both these species, gonocoxal processes are greatly developed ( Jaschhof & Jaschhof 2013: fig. 78C; this paper, Fig. 7 View FIGURE 7 C, ↓) and tegmen processes are larger than is average in this genus ( Jaschhof & Jaschhof 2013: fig. 78B; this paper, Fig. 7 View FIGURE 7 D, ↓). As for interspecific differences, there are 2 pairs of long tegmen processes in T. moldaviensis ( Jaschhof & Jaschhof 2013: fig. 78B), but only 1 such pair in T. wilksae (Fig. D, ↓); the gonostylus apex is broadly rounded in T. moldaviensis ( Jaschhof & Jaschhof 2013: fig. 78A), but pointed in T. wilksae (Fig. A, ↓); and the posterior margin of ninth tergite is slightly concave in T. moldaviensis ( Jaschhof & Jaschhof 2013: fig. 78C), but deeply emarginate in T. wilksae (Fig. B, ↓).

Other male characters. Body size 1.4 mm. Head. Eye bridge 1–3 ommatidia long dorsally. Scape and pedicel concolorous with flagellum. Neck of fourth flagellomere 1.8 times longer than node; circumfilum as typical in Tetraneuromyia ( Jaschhof & Jaschhof 2013) . Palpus as long as head height. Thorax. Anepisternum asetose. Wing. 3.0 times longer than wide. M absent. CuA1 faint. Legs. Basitarsi, claws, and empodia as typical in Tetraneuromyia . Tarsi not white-tipped. Terminalia ( Fig. 7 View FIGURE 7 ). Ninth tergite well sclerotized, especially medioposteriorly (Fig. B). Gonocoxal emargination small, U-shaped (Fig. C). Gonostylus bent inwards (Fig. A). Tegmen (Fig. D): only ventral processes greatly developed, pointed, strongly curved ventrally, dorsal processes rudimentary, blunt-ended, directed dorsally. Ejaculatory apodeme very long, with pointed, weakly sclerotized apex (Fig. C).

Etymology. This species is named after Anne Wilks, Ullevi, Öland.
