Diagnosis 
Males with flagellum longer than head width, hind basitarsus 
with large apical projection and hind tibia with weak setae. 
Female frons and clypeus closely covered with erect, weakly- 
branched, curly hair. The labrum of both sexes smoothly 
convex. 
Descriptions 
Male .—Head width 2.1 mm, body length 6.8 mm. Relative 
dimensions: HW 50, HL 46, UID 39, UFW 36, LID 30, 
HVO 3, WOC 21, OOD 10, IAD 8, ASD 5, AOD 7, SL 18, 
SW 5, FL 71 .—Inner orbits strongly convergent ventrally; 
clypeus transversely convex, longitudinally almost flat; 
labrum smoothly convex; flagellum longer than head 
width; metanotum with weak nodule; propodeal triangle 
subhorizontal basally, rounding smoothly onto vertical 
half. Hind tibia slender, maximum width 0.22x length, 
bearing 7 stiff setae, weaker than those of other species and 
inclined apically; hind tibial spurs large, weakly recurved, 
outer 0.83x as long as inner; hind basitarsus flat, narrow, 
width 0.25x length, with large distal projection on anterior 
margin (Fig. 11). Metasomal T2 with postgradular area 
weakly depressed; S6 with polished medial ridge; S7,8 
and genitalia as in Figs. 21-23 .—Integument black except 
flagellum brown becoming orange-brown towards apex,
