Anocha grytsjoenensis View in CoL sp. nov.

Fig. 2A–C View FIGURE 2

Diagnosis. The eye-bridge is incomplete; the tines of the long M1+2-fork run parallel to each other ( Fig. 2C View FIGURE 2 ). Male flagellomeres are fully covered with conspicuously coarse microtrichia ( Fig. 2B View FIGURE 2 ). The ejaculatory apodeme is spoon-shaped ( Fig. 2A View FIGURE 2 ). Females are unknown.

Differential diagnosis. Anocha glabra , a species with male genitalia similar to that of A. grytsjoenensis , differs in having a complete eye-bridge and glabrous flagellomeres.

Other male characters. Body size 2.6–2.8 mm. Head. Eye-bridge 5–6 ommatidia long at vertex. Postocular bristles 2–3. Neck of fourth flagellomere 1.6 times longer than node ( Fig. 2B View FIGURE 2 ). Wing. Membrane fully setose. Point of furcation of M1+2 situated clearly proximal to apex of M4 ( Fig. 2C View FIGURE 2 ). Terminalia ( Fig. 2A View FIGURE 2 ). Ninth tergite trapezoid. Gonocoxites wider than long, ventral emargination broadly V-shaped, membranous and faintly contoured on inferior half; membranous window narrow; ventrobasal edge convex. Gonostylus 2.2 times longer than wide; apical tooth large, covering most of gonostylar apex, adpressed basally to gonostylar body. Tegmen subtrapezoid. Aedeagal teeth about 10-15.

Etymology. The species epithet, grytsjoenensis , is an adjective derived from the type-locality, Grytsjön Nature Reserve.

Types. Holotype. Male (no. CEC393), Sweden, Småland , Nybro , Bäckebo, Grytsjön Nature Reserve, mixed old-growth taiga, 30 Sep.–30 Nov. 2015, Malaise trap, M. & C. Jaschhof (in NHRS). Paratype . Male (no. CEC394), same data as the holotype but thin aspen forest (in SDEI).

Distribution and phenology. Sweden (Småland). The two specimens known of this species were collected in late autumn in woodland.
