(Figures 2 A–F)
Holotype male, AUSTRALIA: TASMANIA: 9 km SE Miena, 10.i.1992, 2660’, M.E. Irwin, B.J. Irwin (MEI 26098) (ANIC).
Paratypes, AUSTRALIA: TASMANIA: 2 males, female, same data as holotype (MEI 26100, 26102) (ANIC), (MEI 26097) (QDPI); male, female, same data as holotype, D.W. Webb (MEI 26099) (INHS), (MEI 26101) (MEIC).
Diagnosis. Frons wider than ocellar tubercle in both sexes; male with multiple poorly defined rows of postocular setae dorsally; legs orange; coxae dark; scutum glossy black with white pubescent stripes; male genitalia not greatly elongate; epandrium elongate; tergite 8 emarginate medially; gonocoxal apodeme only slightly longer than gonocoxite length; hypandrium with posterolateral lobes overlain with dense setae; distiphallus recurved dorsally.
Description. Male. Body length: 7.5–9.0 mm.
Head. Frons wider than ocellar tubercle at narrowest point, antennal base positioned low on frons; upper frons slightly raised, rounded; lower frons slightly rugose, flattened, lower frons and face scarcely protruding anteriorly, frons and face glossy black, short, dark setae sparsely distributed on frons, setae longer on upper frons, silver pubescence laterally on frons along margin of eye, and on face beside and below antennal base; ocellar tubercle slightly raised, black with short dark setae; occiput convex, glossy black, overlain with sparse grey pubescence medially, multiple poorly-defined rows of relatively long, black postocular setae dorsally; gena black, overlain with silver-white pubescence admixed with long, white setae; palp and labellum brown with scattered dark setae; antenna orange-brown, overlain with brown grey pubescence, shorter than head, scattered, dark setae on scape, pedicel and base of flagellum.
Thorax. Glossy black; scutum overlain with two dorsocentral stripes of silver-white pubescence, coalescent posteriorly as a single broad medial stripe ending on scutellum, postpronotal lobe and notopleural area overlain with silver-white pubescence, scutum sparsely covered with short, dark setae; scutal macrosetae black; silver stripe of velutum on pleuron running through proepisternum, proepimeron, dorsal portion of katepisternum, and meron; coxae glossy dark-brown, pale setae on anterolateral surfaces; legs orange with sparse, pale setae; wing hyaline with translucent brown infuscation in cells posterior cubital (cu-p), third medial (m3), discal (d), basal portion of second+third radial cell (r2+3), and portions of basal radial (br) and basal medial (bm) cells; venation brown; haltere stem brown, knob white; scutal chaetotaxy (pairs): np, 3–5; sa, 1–2; pa, 1–2; dc, 4–7; sc, 1.
Abdomen. Glossy black-brown with scattered pale setae, setae on terminalia pale; tergite 1 with silverwhite pubescence laterally, brown pubescence dorsally on segments 1–5, intersegmental membrane of segments 2–4 white; terminalia dark.
Male genitalia. Epandrium arched with lateral margins extending ventrally (Fig. 2 A), posterolateral corners extending posteriorly as narrow, apically spatulate processes; cercus quadrangular in shape, narrowed apically; tergite 8 medially emarginate (Fig. 2 B); gonocoxal process much shorter than gonostylus (Fig. 2 C); inner gonocoxal process equal length to gonostylus; gonocoxal apodeme ca. equal length of gonocoxite; ventral lobe small, projecting dorsomedially; medial atrium small; hypandrium separate from gonocoxites, quadrangular, bilobed on posterior margin (Fig. 2 D); sternite 8 quadrangular; aedeagus relatively short, distiphallus recurved dorsally proximal to ejaculatory apodeme (Figs 2 E–F); lateral ejaculatory apodeme and ejaculatory apodeme enlarged.
Female. Body length: 7.0–9.0 mm.
Similar to male except: Frons slightly wider than male frons; shorter setae on thorax and abdomen.
Female genitalia. Spermathecal sac elongate, cordate basally, single lobed; 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 Latin: affinis, related to; referring to the external similarity of this species to B. actuosa.
Comments. Bonjeania affinis sp. nov. is very similar in external appearance to B. actuosa but the male genitalia of this species are quite different as the genitalic apodemes are not greatly enlarged. This species is known from a single series from NW Tasmania.
