( Fig. 116 )

Description. Female. Body length 2.9 mm, wing length 2.3 mm. Occiput black. Anterior ocellars long, proclinate; posterior ocellars minute. Inner verticals long, outer ones shorter. Antenna ( Fig. 116 ) entirely brownish yellow. Pedicel with circlet of subequally short setulae. Postpedicel about 3.0 times longer than wide. Style normally pubescent, brown, 4.0 times longer than postpedicel and 2.5 times as long as scape, pedicel and postpedicel combined. Palpus yellow, small, rounded.

Thorax yellow, scutum with elongate brown spot above wing base, metanotum in middle and metapleuron in upper part brownish. Prothoracic episterna lacking long upturned bristle just above fore coxa, with 1 very short bristle in upper part. Postpronotal bristle short. Mesonotum with usual set of bristles. Acrostichals 2- serial, incomplete; dorsocentrals 1-serial, complete.

Legs largely yellow, tibiae and tarsi rather brownish yellow. 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 lacking prominent bristles, with hardly prominent rounded apical projection. Tarsi of all legs unmodified.

Wing uniformly finely infuscate. Costal index: 55/31/46/20. Veins R4+5 and M1+2 slightly divergent near wing apex, both straight. Crossvein bm-cu almost transverse. Crossvein r-m before middle of cell bm. Halter darkened.

Abdomen. Tergite 1 entirely pale yellow. Tergites 2 and 3 with brownish subtriangular spaces, divided along midline, with unmodified setation. Tergites 4 broadest, brown, with numerous squamiform setae. Tergite 5 narrow, with unmodified setae. Tergites 6–7 brownish yellow. Segment 8 brownish, rather short, with sclerites separated; sternite 8 folded apically. Cercus brownish yellow.

Male. Unknown.

Material examined: SINGAPORE, 1 ♀, Nee Soon , 14 October 2005, swamp forest, Mal 4 (reg. 25391, leg. PG, E-58) .

Remarks. Within the key to Elaphropeza this unnamed species would run to E. tiomanensis sp. nov. and E. acantha sp. nov. differing primarily from these species by its scutal pattern.

Species Complex 2.—Hind tibia with 1–2 anterodorsal bristles in middle part
