Anocha japonica View in CoL sp. nov.

Diagnosis. The eye-bridge is incomplete; veins posterior to R4+5 are so weak that they are indiscernible in the only specimen available of this species. Male genitalic structures typical of Anocha japonica are the subcylindrical, almost straight gonostyli provided with a long, pale apical tooth, and the gonocoxites, which are as long as wide and have a deeply V-shaped ventral emargination ( Fig. 3A View FIGURE 3 ). Females are unknown.

Differential diagnosis. Anocha japonica differs from A. minuta , a species with similar male genitalia ( Jaschhof & Jaschhof 2009: fig. 21C), as follows: the scape is setose (asetose in A. minuta ); the scutum has both lateral and dorsocentral setae (only lateral setae); the wing membrane is fully setose (almost asetose); the posterior wing veins are indistinct (distinct); and the toothed claws are single-pointed apically (toothless, two-pointed).

Other male characters. Body size 2.1 mm. Head. Eye-bridge 5 ommatidia long at vertex. Postocular bristles absent. Flagellomeral nodes with sparse microtrichia on basal halves (not drawn in Fig. 3B View FIGURE 3 ). Neck of fourth flagellomere 1.8 times longer than node ( Fig. 3B View FIGURE 3 ). Apical palpal segment subcylindrical, not club-shaped. Terminalia ( Fig. 3A View FIGURE 3 ). Ninth tergite small, posterior edge sinuous (apparently no artifact of preparation). Gonocoxites: membranous window narrow, ventrobasal edge slightly convex. Gonostylus twice as long as wide, pointing dorsomedially; apical claw protruding, not adpressed. Tegmen subtrapezoid. Aedeagal teeth about 10, slightly larger than in other Anocha .

Etymology. The species epithet, japonica , is an adjective referring to Japan, the only distribution known of this species.

Holotype. Male (no. CEC403), Japan, Honshu, Ibaraki, Kitaibaraki , Sadanami , Ogawa Research Forest , mature broadleaf forest, 1 Dec. 1999 – 2 March 2000, Malaise trap, M. & C. Jaschhof (in KUEC).

Distribution and phenology. Japan (Honshu). The only specimen known of Anocha japonica was collected in winter in a mature broadleaf deciduous forest.
