( Figs 26, 71, 116)

Description. FEMALE (holotype). Body length 6.81 mm. LFW 4.52 mm.

Coloration. Head dark castaneous almost black; scape dark castaneous; pedicel and flagellum castaneous; mandible dark castaneous; palpi light castaneous; mesosoma dark castaneous almost black; tegula dark castaneous; wing venation dark castaneous; procoxa dark castaneous almost black; mesocoxa and metacoxa dark castaneous; trochanters castaneous; femora dark castaneous; tarsi light castaneous; metasoma dark castaneous with light castaneous portions along its length.

Head ( Fig. 26). Head wider than long, subtriangular in profile; gena strongly concave in profile. Mandible evenly wide, two lowermost teeth larger than upper ones, lower tooth curved inward, lower margin strongly setose. Clypeus coriaceous-punctate, median clypeal lobe angulate, median concavity of median clypeal lobe absent, 0.09 LH, well marked off from frons, median carina present, 0.26 LH. Malar space conspicuous, 0.58 mandibular base. Antenna 2.0 mm; first five antennomeres in ratio of about 11:10:10:10:10; flagellomere 1 1.0 longer than wide, flagellar pubescence dense, with many outstanding erect setae; anterior carina present. Region between torulus and eye straight. Area between the anterior margin of eyes and demarkation of median clypeal lobe 0.13 LH. Eye protuberant, 0.55 LH, with dense hairs, located more laterally, lower margin without strong depression. Frons coriaceous-punctate. WH 1.1 LH. WF 0.64 WH. WF 1.33 HE. OOL 0.86 WOT. VOL 0.42 HE. Distance from posterior ocellus to vertex crest 0.5 DAO. Ocelli small, DAO 0.08 WF, ocellar triangle not compact, distance between posterior ocelli 3.25 DAO, anterior ocellus not surpassing imaginary top eye line, posterior ocellus almost reaching vertex. Vertex straight, long setae, 0.40 LH, temple profile slightly convergent in dorsal view, with corner angulate, not projected postero-laterad. Hipostomal carina, angulate, low.

Mesosoma ( Fig. 71). Pronotal disc coriaceous-punctate, 0.43 as long as wide, anterior corner rounded, posterior margin concave medially, pronotal disc without short longitudinal furrow. Parapsidal furrow wholly conspicuous. Notauli convergent posterad. Mesoscutum 1.18 length pronotal disc. Scutellum coriaceous-punctate, 0.95 length pronotal disc, almost flat in profile, scutellar pit elliptical, dilated, distant each other 7.5 its own diameter. Dorsal axillar surface with fovea oval. Metanotum with median region high, coriaceous-puncticulate, as high as scutellum in profile, with fovea oval laterally. Propodeal disc wider than long; anterior margin without foveolate or transverse furrow; median carina 0.83 length propodeal disc, incomplete posterad; discal carina 0.28 length propodeal disc, converging posterad, slightly arched; space between median and discal carina confused- until cervical collar absent. Prosternum with median excavation complete, median suture absent. Mesopectus with posterior depression heart-shaped; median suture not evident.

Wings. Macropterous. Forewing ( Fig. 116) with 1M cell subpentagonal; 1M and 1R1 cells not aligned basally; C cell evenly narrow; 1R1 cell present, distinctly longer than 2R1 cell, wider medially; Rs b convex; 2R1 0.16 LFW; distal margin of Rs c convex; r-rs vein inclined; R1 b entirely on anterior margin of forewing; Cu b absent; Rs+M vein 1.3 Rs a; M vein 1.17 Rs a; Rs a subperpendicular to anterior margin of forewing; stigma rectangular; distal stigmal margin truncate. Hind wing with four distal hamuli, last hamulus discontinuous each other.

Legs. Profemur swollen, 0.56 as wide as long. Metacoxa with median region 0.5 as wide as long. Metacoxal projection in dorsal region incospicuous, apex sharpened.

Metasoma. 0.4 as wide as long.

MALE. Unknown.

Material examined. Holotype ♀. AUSTRALIA, Tas [mania], 41.50S 146.03E, Pelion Hut, 3 Km S, M[oun]t[ain] Oakleigh, 5–10 Feb [ruay] 1990, I.D.Naumann, ANIC GoogleMaps   . Paratypes. AUSTRALIA, Tas [mania], 2 ♀, 41.50S 146.03E, Pelion Hut, 3 Km S, M[oun]t[ain] Oakleigh, open forest, (W. E. B. S.), Malaise 1, 4 Apr [il]– 15 May 1990, ANIC GoogleMaps   ; 1 ♀, 43.25S 146.10E, Melaleuca, Bathurst Harbour, 12–17 Feb [ruary] 1990, I.D.Naumann, ANIC GoogleMaps   .

Distribution. Australia (Tasmania).

Variation. Body length 6.42–6.67 mm; LFW 4.76–5.00 mm; veins of forewing dark castaneous; legs castaneouss; posterior tergites yellowish.

Remarks. This species has features common to most species of the genus by having the eyes large, the median clypeal lobe angulate, with median carina extending to the frons and vertex crest straight. However this species has the gena with strong and clear concavity which is visible in lateral view, and even more evident in ventral view.
