( Fig. 84)

Diagnosis. Occiput, antenna, thorax and legs entirely yellow; postpedicel short, nearly 2.0 times longer than wide; tibiae lacking prominent bristles (except subapicals).

Inner verticals long, outer ones somewhat shorter. Antenna ( Fig. 84) with scape and pedicel yellow, postpedicel brownish. Pedicel with circlet of subequally short setulae. Postpedicel nearly 2.0 times longer than wide. Style normally pubescent, brown, about 4.0 times longer than postpedicel and nearly 2.5 times as long as scape, pedicel and postpedicel combined. Palpus yellow, small, rounded.

Thorax entirely yellow. Prothoracic episterna with 1 long upturned bristle just above fore coxa and short bristle in upper part. Postpronotal bristle minute. Mesonotum with usual set of bristles. Acrostichals and dorsocentrals multiserial, extending to base of scutellum, 1 pair of prescutellars longest.

Legs entirely yellow. Fore and mid femur with ordinary 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, lacking prominent bristles. Tarsi of all legs unmodified.

Wing finely infuscate and with indistinct brownish band in middle (almost invisible near posterior margin of wing). Costal index: 28/27/23/12. Veins R4+5 and M1+2 divergent near wing apex, both straight. Crossvein bm-cu oblique. Crossvein r-m somewhat beyond middle of cell bm. Halter yellow.

Abdomen. Tergite 1 pale yellow, tergites 6 and 7 yellowish. Tergites 2–5 of subequal width viewed laterally, brownish; tergite 2 somewhat narrower, broadly concave on anterior margin.

Remarks. Within the key to Elaphropeza this unnamed species would run to E. ferruginea Brunetti differing primarily from it by wing colour and yellow scutellum.
