( Fig. 191)

Description. Female. Body length 2.3 mm, wing length 1.8 mm. Occiput black. Anterior ocellars moderately long, proclinate; posterior ocellars minute. Inner verticals long, outer ones short. Antenna ( Fig. 191) with postpedicel brown, scape and pedicel somewhat paler, rather reddish brown. Pedicel with circlet of subequally short setulae. Postpedicel about 5.0 times longer than wide. Style normally pubescent, about as long as postpedicel and somewhat (1.3 times) shorter than scape, pedicel and postpedicel combined. Palpus yellow, small, rounded.

Thorax entirely yellow, some sutures brownish in varying extent. Prothoracic episterna lacking long upturned bristle just above fore coxa, with short bristle in upper part. Postpronotal bristle minute. Mesonotum with usual set of bristles. Acrostichals and dorsocentrals multiserial, extending to base of scutellum.

Legs largely yellow, fore tibia and tarsus, mid and hind tarsomeres 2–5 brownish. Fore and mid femur with unmodified armature. Fore tibia lacking prominent bristles. Mid tibia lacking ventral spinules and prominent bristles (except subapicals). Hind femur with ordinary setation. Hind tibia with hardly prominent rounded apical projection, bearing 1 anterodorsal and 1 long, black, straight subapical bristles. Hind tarsomere 1 somewhat thickened.

Wing uniformly finely brownish infuscate. Costal index: 39/32/25/17. Veins R4+5 and M1+2 divergent near wing apex, both straight. Crossvein bm-cu transverse. Crossvein r-m near middle of cell bm. Halter dark.

Abdomen. Tergite 1 wholly pale yellow. Tergites 2 and 3 brownish, of subequal width, subtriangular viewed laterally, narrowly separated dorsally; with unmodified setation. Tergite 4 broadest, dark brown, with squamiform setae. Tergite 5 very narrow, dark brown, with squamiform setae. Tergites 6 and 7 unmodified. Segment 8 narrow, elongate, brown, with sclerites separated; sternite 8 somewhat folded apically. Cercus brown.

Material examined. SINGAPORE, 1 ♀, Chek Jawa , 2 December 2003, mangrove, Mal 1 (reg. 23097, leg. PG, E-49) .

Remarks. Within the key to Elaphropeza this unnamed species would run to E. asiophila sp. nov. differing by the shorter postpedicel, colour of legs, presence of 1 long, black, straight subapical bristle on the hind tibia and some other characters.
