Neoempheria biceltisuta View in CoL sp. n.

[Japanese name: futanomi-nagamado-kinoko-bae] ( Figs. 2 View FIGURE 2 a, 3a, 5, 9a–e)

Description. Body length: 3.8–4.4 mm (n= 2) in male, 4.2 mm (n= 1) in female. Wing length: 4.4 mm (4.0– 4.6 mm, n = 3) in male, 5.3 mm (n= 1) in female. Wing ( Fig. 3 View FIGURE 3 a): vein sc-r ending basal 1/3 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, apex of gonocoxal lobe and surrounding parts brown to dark brown, basal portion of aedeagus yellow ( Fig. 5 View FIGURE 5 a). Sternite 9 ( Fig. 9 View FIGURE 9 a: S9) narrow, less than 1/10 as wide as long, visible as seam between gonocoxites, without sternal projection. Gonocoxite 9 ( Fig. 9 View FIGURE 9 a, b: gc) with gonocoxal lobe ( Fig. 9 View FIGURE 9 a: gl) truncate at apex. Gonostylus ( Fig. 9 View FIGURE 9 a: gs) slender, apical 1/4 less than 1.5 times as wide as base. Aedeagus ( Fig. 9 View FIGURE 9 a, b) dilated on apical half, without projections. Sclerotized part of aedeagus ( Fig. 9 View FIGURE 9 a: sa) tapered to apex, with slender, angled lateral extension. Female: S7 with uniform setae on posterior margin, posterior margin with deep medial indentation. S8 triangular in ventral view. Gonocoxite 8 ( Fig. 9 View FIGURE 9 c: gc8) small, recognizable as bump at sublateral portion in posterior margin of S8. Gonapophysis 8 ( Fig. 9 View FIGURE 9 c: gp8) dilated in apical half, with acute apex, dentate on dorsal margin. Gonocoxite 9 ( Fig. 9 View FIGURE 9 d, e: gc9) yellow, without projections. Gonapophysis 9 ( Fig. 9 View FIGURE 9 d, e: gp9) yellow, with 2 indistinct ventral sublateral ridges ( Fig. 9 View FIGURE 9 e: vr), gradually tapered to apex with gonopore.

Specimens examined. Holotype. Male, “ Thailand, Phuket/ Marine Biol. Center/ 13.-16.xi.1987 / Mogens Andersen leg.”, green disk label, “Ne.7004” (ZMCU). Paratypes: same data as holotype (1♂, 1♀, Ne.7005, 7006; ZMCU); same data as holotype except, 17–21.xi.1987 (1♂, Ne.7007; ZMCU).

Etymology. The specific epithet is derived from Latin and refers to the broad, truncate, chisel-like (celtis-) apex of the two (bi-) gonocoxal lobes ( Fig. 9 View FIGURE 9 a).

Distribution. Thailand (Phuket) ( Fig. 5 View FIGURE 5 ).

Remarks. This species is distinguished from similar species by the broad, truncate apex of the male gonocoxal lobe ( Fig. 9 View FIGURE 9 a), and in the female by the dentate dorsal margin of the gonapophysis 8 ( Fig. 9 View FIGURE 9 c), and yellow gonapophysis 9 with indistinct ventral sublateral ridges ( Fig. 9 View FIGURE 9 e).
