Anocha grytsjoenensis Jaschhof, 2017, sp. nov.

Description

Anocha grytsjoenensis sp. nov.

Fig. 2A–C

Diagnosis. The eye-bridge is incomplete; the tines of the long M1+2-fork run parallel to each other (Fig. 2C). Male flagellomeres are fully covered with conspicuously coarse microtrichia (Fig. 2B). The ejaculatory apodeme is spoon-shaped (Fig. 2A). 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). Wing. Membrane fully setose. Point of furcation of M1+2 situated clearly proximal to apex of M4 (Fig. 2C). Terminalia (Fig. 2A). 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).
