Head dark castaneous; scape light castaneous; pedicel light castaneous; flagellum light castaneous; mandible light castaneous with teeth dark castaneous; palpi light castaneous; mesosoma dark castaneous; tegula, wing venation light castaneous, coxae, trochanters, femora light castaneous and tarsi light castaneous; metasoma dark castaneous with light castaneous portions along its length.

Head ( Fig. 17 ). Head longer than wide, subrectangular in profile; gena without concavity in profile. Mandible evenly wide, two lowermost teeth larger than upper ones, lower tooth curved inward, lower margin strongly setose. Clypeus coriaceous, median clypeal lobe angulate, median concavity of median clypeal lobe absent, 0.01 LH, well marked off from frons, median carina present, 0.12 LH. Malar space inconspicuous, 0.13 mandibular base. Antenna 1.43 mm; first five antennomeres in ratio of about 8:10:10:10:10; flagellomere 1 1.25 longer than wide, flagellar pubescence dense, with few outstanding erect setae. Region between torulus and eye straight. Area between the anterior margin of eyes and demarkation of median clypeal lobe 0.05 LH. Eye not protuberant, 0.47 LH, with sparse hairs, located more dorsally, lower margin without strong depression. Frons coriaceous. WH 0.81 LH. WF 0.57 WH. WF 1.0 HE. OOL 1.17 WOT. VOL 0.67 HE. Distance from posterior ocellus to vertex crest 1.5 DAO. Ocelli large, DAO 0.14 WF, ocellar triangle compact, distance between posterior ocelli 0.8 DAO, anterior ocellus not surpassing imaginary top eye line, posterior ocellus distant from vertex. Vertex straight, short setae, 0.12 LH, temple profile approximately parallel in dorsal view, with corner convex, not projected postero-laterad. Hipostomal carina arched, high.

Mesosoma (Fig. 62). Pronotal disc coriaceous-punctate, 0.35 as long as wide, anterior corner angulate, posterior margin concave medially, pronotal disc without short longitudinal furrow. Parapsidal furrow conspicuous only at third posterior part. Notauli convergent posterad. Mesoscutum 0.96 length pronotal disc. Scutellum coriaceous-punctate, 0.87 length pronotal disc, almost flat in profile, posterior margin convex medially, scutellar oval laterally. Propodeal disc as long as wide; anterior margin without foveolate or transverse furrow; median carina 0.83 length propodeal disc, incomplete posterad; discal carina 0.65 length propodeal disc, converging posterad, straight; space between median and discal carina imbricate and confused-rugulose. Mesopleuron with subtegular furrow elliptical; mesepimeral suture almost inconspicuous posterad; mesopleural epicoxal lobe inconspicuous. Propleuron with sequence of foveae from anterior margin of prosternum until cervical collar absent. Prosternum with median excavation complete, median suture present. Mesopectus with posterior depression heartshaped; median suture not evident.

Wings. Macropterous. Forewing ( Fig. 107 ) with 1M cell subpentagonal; 1M and 1R1cells not aligned basally; C cell widening distally; 1R1 cell present, slightly longer than 2R1 cell, evenly wide; Rs b straight; 2R1 cell 0.18 LFW; distal margin of Rs c convex; r-rs vein strongly inclined; R1 b entirely on anterior margin of forewing; Cu b absent; Rs+M vein 0.90 Rs a; M vein 1.5 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, 0.43 as wide as long. Metacoxa with median region 0.86 as wide as long. Metacoxal projection in dorsal region conspicuous, apex rounded.

Metasoma. 2.59 as wide as long, ventral carina of petiole present.

MALE. Unknown.

Material examined. Holotype ♀. AUSTRALIA, Q[ueensland], 19.00S 146.12E, Paluma, 900 m, 25 Oct [ober]–3 Nov [ember] 1980, D.Frith, Malaise Trap, ANIC . Paratypes. AUSTRALIA, Q[ueensland], 19.00S 146.12E, 2 ♀, Paluma, 900 m, 25–31 Oct [ober] 1980, D.Frith, Malaise Trap, ANIC .

Distribution. Australia (Queensland).

Variation. Body length 3.71–4.05 mm; LFW 3.57–4.05 mm; distance between posterior ocelli slightly larger than diameter of anterior ocelli.

Remarks. This species is very different of the others by having the head elongate, the area between the anterior margin of eyes and demarkation of median clypeal lobe short, the ocellar triangle compact and the eyes more dorsally located.
