( FIGURE 2 View FIGURE 2 A–E)
Diagnosis. Male, body in dark brown. Eyes bare; palpal third segment swollen with a small and deep sensory pit; wing without macrotrichia, CR=0.72, second radial cell broad and 2 times longer than first one; posterior border of scutellum with 4 stout bristles; hind tibia with 7 distal bristles; genitalia short and stout, gonostylus arm-shaped, aedeagal parameral complex long foot-like.
Description. Male, Moderate size ( Fig. 2 View FIGURE 2 A). Compound eyes bare, 4–10 antenna segments with long and dense verticil hairs; palpal segments in proportion of 8:16:25:11:16, the third segment swollen with small, deep sensory pit ( Fig. 2 View FIGURE 2 C); clypeus with 5 short, small bristles medially ( Fig. 2 View FIGURE 2 D). Thorax dark brown, legs pale brown; wing length 1.73mm,width 0.41mm, wing without macrotrichia; costa extending two-thirds of wing length, second radial cell broad and 2 times longer than first ( Fig. 2 View FIGURE 2 B); scutellum with 4 stout bristles; hind tibia with 7 bristles, 24 comb teeth. TR (I) 3.28, TR (II)2.92, TR (III)2.98. F-T(I) 173:168:105:32:–:–:–, F-T(II) 218:201:111:38:28:–:–, F-T(III) 208:201:125:42:21:20:21.Abdomen: tergum brown, genitalia short, stout caudal, margin of ninth tergum rounded, posterior border of ninth sterna straight. Gonostylus slender, arm-shaped, gonocoxite stout, ventral roots long, slender; aedeagal parameral complex long foot-like; median part of aedeagal parameral complex slightly convex at apex ( Fig. 2 View FIGURE 2 E).
Discussion. This species resembles to Atrichopogonfulvus Macfie, Atrichopogon jacobsoni (de Meijere), ( Wirth & Ratanaworrabhan, 1992, 1993) and Atrichopogon granditergitus ( Borkent & Picado, 2004) in the structure of the genitalia. However, the former two species have the posterior border of the scutellum with 6 stout bristles and the latter species has cell r5 with dense macrotrichia. The new species is distinguished by the eyes bare, posterior border of scutellum with 4 stout bristles, aedeagal parameral complex long foot-like and wings without macrotrichia.
