Diagnosis. Lower frons and face protruding anteriorly; wing costal margin dark infuscate; scutum bright orange; head, pleuron and abdomen black; male genitalia with epandrium much shorter along midline than width; aedeagus and gonocoxal apodemes greatly elongate; ejaculatory apodemes enlarged; hypandrium narrow, band-like.

Description. Male. Body length: 6.0–8.0 mm.

Head. Frons only slightly narrower than ocellar tubercle at narrowest point, antennal base positioned low on frons; upper frons flat, lower frons and face protruding anteriorly ( Fig. 4 A); frons and face glossy black; short, dark setae sparsely distributed on frons; three elongate patches of silver pubescence laterally on frons along margin of eye, two patches on face beside and below antennal base; ocellar tubercle slightly raised, black with sparse, grey pubescence posteriorly, admixed with short dark setae; occiput concave, black, overlain with grey pubescence; single row of relatively short, black, postocular setae; gena black with long, black setae, silver-white pubescence along margin of eye; palp and labellum brown with scattered, dark setae; antenna dark brown, approximately equal length to head; dark setae on scape and pedicel, flagellum with small patches of short dark setae dorsally and ventrally; flagellum wider and longer than scape and pedicel; scape glossy; pedicel and flagellum overlain with grey pubescence.

Thorax. Scutum and scutellum bright orange; presutural area of scutum with broad, black, medial stripe ending at transverse suture, occasionally with a pair of small dark spots at posterior end of stripe; scutum sparsely covered with short, pale setae; scutal macrosetae black; pleuron, sternum and coxae glossy black, short, dark setae on anepisternum, katepisternum, katatergite and coxae; legs black-brown with sparse, dark setae on femora; approximate mid-point of tibia with yellow-cream coloured band; tarsi yellow-cream, individual tarsomeres brown distally; wing translucent, brown infuscate anteriorly, fading to clear hyaline posteriorly; venation dark; haltere brown; scutal chaetotaxy (pairs): np, 4–5; sa, 1; pa, 2; dc, 1–2 [slender]; sc, 1.

Abdomen. Black-brown with scattered, dark setae laterally, setae on terminalia pale; brown pubescence dorsally on segments 1–5.

Male genitalia. Epandrium much shorter than wide, deeply emarginate on both posterior and anterior margin ( Fig. 4 B); cercus rounded; tergite 8 only slightly medially emarginate ( Fig. 4 C); gonocoxal process slightly shorter than gonostylus ( Figs 4 D–E); inner gonocoxal process equal length to gonostylus; gonocoxal apodeme ca. 3x length of gonocoxite; hypandrium reduced, band-like, leaving large, membranous medial atrium; ventral lobe reflexed dorsomedially, narrow apically; sternite 8 broadly trapezoidal ( Fig. 4 E); aedeagus elongate, distiphallus recurved dorsally proximal to ejaculatory apodeme ( Fig. 4 D); lateral ejaculatory apodeme relatively small; ejaculatory apodeme enlarged; arms of ventral apodeme of aedeagal sheath relatively broad in profile.

Female. Body length: 5.5–8.0 mm.

Similar to male except: Frons much wider than ocellar tubercle at narrowest point; frons with two lateral spots of silver pubescence along eye margin; scutum without black stripe; thorax and abdomen with shorter darker setae covering.

Female genitalia. Spermathecal sac rounded, single lobe, spermathecal sac duct relatively long, without sclerotised band, single membranous, round spermatheca; spermathecal duct joined to spermathecal sac duct proximal to base of spermathecal sac; accessory gland elongate, relatively small.

Etymology. The specific epithet is derived from Greek: bapsis , a dipping, dyeing; referring to the bright orange coloured dorsum of the thorax that appears to be coloured artificially.

Comments. Bonjeania bapsis sp. nov. is most closely related to B. webbi sp. nov. This species is distributed throughout central and southern Queensland to central New South Wales, inland from the coast.
