Neoempheria ferruginea: Sasakawa 1964: 23   ; Sasakawa 2005: 277.

Description. Body length: 5.2 mm (4.5–5.6 mm, n= 7) in male, 5.3 mm (4.5–5.8 mm, n= 7) in female. Wing length: 5.4 mm (4.3–5.5 mm, n= 10) in male, 5.0 mm (4.5–5.6 mm, n= 7) in female. Wing ( Fig. 3 View FIGURE 3 b): vein sc-r ending in basal 1 / 4 of anterior margin of cell r 1. Vein Rs as long as distance between basal end of vein Rs and apical end of vein sc-r. Male: genitalia yellow, at most darkened at gonocoxal projection, basal portion of aedeagus yellow. Sternite 9 narrow, produced posteriorly as sternal projection ( Figs. 4 View FIGURE 4 b, 10 a, 10 b: sp) bifurcate and upturned at apex, visible in lateral view. Gonocoxite ( Figs. 4 View FIGURE 4 b, 10 a, 10 b: gc) without gonocoxal lobe. Gonostylus ( Figs. 4 View FIGURE 4 b, 10 a: gs) slender, apical half less than 1.5 times as wide as base. Aedeagus ( Fig. 4 View FIGURE 4 b, 10 a, 10 b) dilated at apical half, without projections. Sclerotized part of aedeagus ( Fig. 10 View FIGURE 10 a: sa) tapered to apex, with slender, angled lateral extension. Female: S 7 with uniform setae on posterior margin ( Fig. 4 View FIGURE 4 c), posterior margin with deep incision at middle. S 8 triangular in ventral view. Gonocoxite 8 ( Fig. 10 View FIGURE 10 c: gc 8) small, recognizable as bump at sublateral portion in posterior margin of S 8. Gonapophysis 8 ( Fig. 10 View FIGURE 10 c: gp 8) dilated in apical half, apex round. Gonocoxite 9 yellow, without projections. Gonapophysis 9 ( Fig. 10 View FIGURE 10 d: gp 9) yellow, with a single ventromedial ridge, gradually tapered to apex with gonopore ( Fig. 10 View FIGURE 10 d, e).

Etymology. The specific epithet is derived from Latin and refers to the forked sternal projection (furcatus) into two (bi -) points at the apex ( Fig. 11 View FIGURE 11 a).

Distribution. Japan (Honshu, Shikoku, Kyushu, and Tsushima) ( Fig. 6 View FIGURE 6 ).

Remarks. This species is distinguished from similar species by the bifurcated sternal projection of the male sternite 9 ( Fig. 10 View FIGURE 10 a), and the female by the round margin of the gonapophysis 8 ( Fig. 10 View FIGURE 10 c), and yellow gonapophysis 9 with a single ventromedial ridge ( Fig 10 View FIGURE 10 e).

The two males (Ne. 3010, Ne. 8001) referred to as N. ferruginea   in Sasakawa (1964, 2005) are actually this species. A pair of specimens (Ne.3008, 3009) was reared from Inocybe   sp. Two pairs of specimens were collected by light traps (Ne.3010, 4002) and malaise traps (Ne.1191, 8001). Other male and female specimens (Ne. 1735–1740) were collected by traps installed on standing tree trunks of Quercus serrata Thunb.   used to collect platypodid bark beetles ( Platypus quercivorus (Murayama))   .
