description: Neoempheria carinata sp. n.
[Japanese name: ryukotsu-nagamado-kinoko-bae] (Figs. 2 e, 3e, 4d, 8, 13a–e)
Description. Body length: 5.7 mm (5.0– 6.5 mm, n= 9) in male, 6.1 mm (4.8–6.7 mm, n= 10) in female. Wing length: 5.3 mm (4.8–6.0 mm, n= 10) in male, 5.6 mm (4.5–6.4 mm, n= 10) in female. Wing (Fig. 3 e): vein sc-r ending basal 3/8 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. Gonocoxal projection black, surrounding part dark brown, basal portion of aedeagus black. S9 (Fig. 13 a: S9) narrow, 1/3 as wide as long, with sternal projection (Fig. 13 a: sp) extending laterally. Gonocoxite (Fig. 13 a, b: gc) without gonocoxal lobe. Gonostylus (Fig. 13 a, b: gs) slender, apical half less than 1.5 times as wide as base. Aedeagus (Fig. 13 a, b) dilated at apical half, without projections. Sclerotized part of aedeagus (Fig. 13 a: sa) tapered to apex, with slender, angled lateral extension. Female: S7 (Fig. 4 d: S7) with uniform setae on posterior margin, posterior margin with deep incision at middle. S8 (Fig. 4 d: S8) triangular in ventral view. Gonocoxite 8 (Fig. 4 d: gc8) small, recognizable as bump at sublateral portion in posterior margin of S8. Gonapophysis 8 (Fig. 4 d: gp8) dilated in apical half, apex round. Gonocoxite 9 yellow, without projections. Gonapophysis 9 black, with 2 ventral sublateral ridges (Fig. 13 e: vr), tapered to apex with gonopore. Depression between ventral sublateral ridges of gonapophysis 9 deep (Fig. 13 e).

Etymology. The specific epithet is derived from Latin and refers to the sternite 9 having a keel-like (carinatus) sternal projection (Fig. 13 a).
Distribution. Japan (Hokkaido, Honshu, and Kyushu) (Fig. 8).
Remarks. This species is distinguished from similar species by the male sternite 9, which has a keel-shaped sternal projection (Fig. 13 a, c), and in the female by the gonopore opening at the apex of an elongated projection, and a dark brown gonapophysis 9 with two distinct ventral sublateral ridges (Fig. 13 e).
All specimens examined were collected at indoor facilities growing fruit bodies of L. edodes in Japan. This species has not been collected outside these facilities leaving no cues to determine the natural origin of the specimens examined. Therefore the geographical distribution (Fig. 8) is unnatural. The type locality, Masawa, Yamagata Prefecture, was selected at random.
