Neoempheria ferruginea: Sasakawa & Tamu 1961: 69 View in CoL .

Description. Body length: 5.3 mm (4.7–5.8 mm, n= 10), 5.4 mm (4.9–6.0 mm, n= 6) in female. Wing length: 5.0 mm (4.5–5.5 mm, n= 10) in male, 5.0 mm (3.7–5.8 mm, n= 10) in female. Wing ( Fig. 3 View FIGURE 3 l): vein sc-r ending basal 1/ 4 of anterior margin of cell r1. Vein Rs as long as distance between basal end of vein Rs and apical end of vein sc-r. Male: genitalia yellow in ground color, with distinct dark marks on sternal projection of sternite 9 and surrounding parts, basal portion of aedeagus yellow. S9 ( Fig. 18 View FIGURE 18 a: S9) broad, wider than long, with pair of sternal projections ( Fig. 18 View FIGURE 18 a: sp) blunt at apex. Gonocoxite ( Fig. 18 View FIGURE 18 a, b: gc) without gonocoxal lobe. Gonostylus ( Fig. 18 View FIGURE 18 a, b: gs) short, apical half 2 times as wide as base. Aedeagus dilated at apical half, with pair of ventral projections ( Fig. 18 View FIGURE 18 a, c: vp). Sclerotized part of aedeagus ( Fig. 18 View FIGURE 18 a: sa) with 2 pairs of extensions, ventral pair supporting projection ( Fig. 18 View FIGURE 18 c: ve), dorsal pair extending to dorsolateral portion of aedeagus ( Fig. 18 View FIGURE 18 c: de). Female: S7 ( Fig. 4 View FIGURE 4 e, f: S7) with strong setae on posterior margin, posterior margin gently convex ( Fig. 4 View FIGURE 4 f). S8 ( Fig. 4 View FIGURE 4 f: S8) quadrate in ventral view. Gonocoxite 8 ( Fig. 4 View FIGURE 4 e, f: gc8) small, recognizable as bump at lateral corner in posterior margin of S8.

Gonapophysis 8 ( Fig. 4 View FIGURE 4 e, f: gp8) slender, with blunt apex. Gonocoxite 9 ( Fig. 4 View FIGURE 4 e, f: gc9) yellow to dark brown, without projections. Gonapophysis 9 ( Fig. 4 View FIGURE 4 e, f: gp9) black, with 2 ventral sublateral ridges ( Fig. 18 View FIGURE 18 e: vr), tapered to apex with gonopore. Depression between ventral sublateral ridges deeply convex.

Distribution. Russia (Sakhalin) and Japan (Hokkaido, Honshu, and Tsushima) ( Fig. 7 View FIGURE 7 ).

Remarks. This species is new to Japan. It is distinguished from other species similar in general appearances by the sternal projection of the male sternite 9 with a blunt apex ( Fig. 18 View FIGURE 18 a), and in the female by the dark brown gonapophysis 9 with two distinct ventral sublateral ridges ( Fig. 18 View FIGURE 18 e). A female (Ne.3011) was referred to as N. ferruginea in Sasakawa & Tamu (1961). One male (Ne.2021) was reared from a larva found under rotting wood. It pupated on 16.vi.2004, and emerged on 18.vi.2004. The skin of the pupa was attached under the pinned specimen.
