description: Neoempheria muticata sp. n.
[Japanese name: togenashi-nagamado-kinoko-bae] (Figs. 2 k, 3k, 6, 17a–e)
Description. Body length: male 4.8 mm (n= 1), female 4.7 mm (n= 1). Wing length: 4.5 mm (3.7–5.3 mm, n= 7) in male, 4.0– 4.6 mm (n= 2) in female. Wing (Fig. 3 k): vein sc-r ending basal 1/3 of anterior margin of cell r1. Vein Rs longer than 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 yellow. S9 narrow, 1/6 as wide as long, without sternal projections. Gonocoxite (Fig. 17 a, b: gc) without gonocoxial lobe. Gonostylus (Fig. 17 a: gs) slender, apical half less than 1.5 times as wide as base. Aedeagus (Fig. 17 a, b) dilated at apical half, without projections. Sclerotized part of aedeagus (Fig. 17 a: sa) tapered to apex, with slender, angled lateral extension. Female: S7 with uniform setae on posterior margin, posterior margin with deep incision at middle. S8 triangular in ventral view. Gonocoxite 8 (Fig. 17 c: gc8) small, recognizable as bump at sublateral portion in posterior margin of S8. Gonapophysis 8 (Fig. 17 c: gp8) dilated in apical half, apex round. Gonocoxite 9 yellow, without projections. Gonapophysis 9 (Fig. 17 d, e: gp9) dark brown to black, with 2 indistinct ventral sublateral ridges (Fig. 17 d: vr), gradually tapered to apex with gonopore. Depression between ventral sublateral ridges of gonapophysis 9 shallow.

Etymology. The specific epithet is derived from Latin and refers to the sternite 9 and gonocoxites lacking (muticus) any projections (Fig. 17 a).
Distribution. Japan (Hokkaido and Honshu) (Fig. 6).
Remarks. This species is distinguished from similar species by the male sternite 9 and gonocoxites lacking any projections (Fig. 17 a), and in the female by the round margin of the gonapophysis 8 (Fig. 17 c) and the brown gonapophysis 9 with two indistinct ventral sublateral ridges (Fig. 17 e).
