Neoempheria forficulata   sp. n.

[Japanese name: hasami-nagamado-kinoko-bae] ( Figs. 2 View FIGURE 2 i, 3 i, 7, 16a, 16 b)

Description. Body length: 5.3 mm (4.8–5.5 mm, n= 3). Wing length: 4. 9 mm (4.8–5.1 mm, n= 3). Wing ( Fig. 3 View FIGURE 3 i): vein sc-r ending 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 in ground color, with distinct dark marks on sternal projection of S 9 and surrounding parts, basal portion of aedeagus yellow. S 9 ( Fig. 16 View FIGURE 16 a: S 9) broad, 5 / 6 as wide as long. Sternal projection ( Fig. 16 View FIGURE 16 a: sp) present, acute at apex, directed posteriorly. Gonocoxite ( Fig. 16 View FIGURE 16 a, b: gc) without gonocoxal lobe. Gonostylus short, apical half 2 times as wide as base. Aedeagus ( Fig. 16 View FIGURE 16 a) dilated at apical half, with pair of ventral projections ( Fig. 16 View FIGURE 16 a, b: vp). Sclerotized part of aedeagus ( Fig. 16 View FIGURE 16 a: sa) with 2 pairs of extensions, ventral pair ( Fig. 16 View FIGURE 16 a: ve) supporting projection, dorsal pair extending to dorsolateral portion of aedeagus. Female unknown.

Specimens examined. Holotype. Male. “Kouyadai/ Tsukuba/ Ibaraki Pref./ 18–26.viii 1993 / T Matsumura/ Malaise trap”, green disk label, “Ne. 5001 ” ( NIAS). Paratypes. JAPAN [HONSHU] Nara P: Mt. Kasuga, Nara C, 2010, H Oishi leg. (1 ♂, Ne. 3001; OMNH). Wakayama P: Koza T, iv. 1962, M Sasakawa leg. (1 ♂, Ne. 3002; OMNH).

Etymology. The specific epithet is derived from Latin and refers to the pair of sternal projections composing a pincer-shaped (forficulatus) structure ( Fig. 16 View FIGURE 16 a).

Distribution. Japan (Honshu) ( Fig. 7 View FIGURE 7 ).

Remarks. This species is distinguished from other species similar in general appearances by a pair of sternal projections in the male, of which the apices are extended posteriorly and pincer-like in shape when viewed from ventral side ( Fig. 16 View FIGURE 16 a).
