Eupsenella larrakia Ramos & Azevedo , sp. nov.

( Figs 40 View FIGURES 39–47 , 85 View FIGURES 84–92 , 130 View FIGURES 123–132 )

Description. FEMALE (holotype). Body length 6.53 mm. LFW 1.43 mm.

Coloration. Head dark castaneous almost black; scape, pedicel and flagellum castaneous; mandible and palpi light castaneous; mesosoma dark castaneous almost black; tegula light castaneous; wing venation castaneous; procoxa dark castaneous; mesocoxa and metacoxa castaneous; trochanters light castaneous; femora castaneous; tarsi light castaneous; metasoma dark castaneous with last tergite light castaneous.

Head ( Fig. 40 View FIGURES 39–47 ). Head longer than wide, subrectangular in profile; gena weakly concave in profile. Mandible with base wider than apex, two lowermost teeth larger than upper ones, lower tooth curved inward, lower margin strongly setose. Clypeus coriaceous-punctate, median clypeal lobe truncate, median concavity of median clypeal about 11:11:11:11:11; flagellomere 1 1.22 longer than wide, flagellar pubescence sparse, with many outstanding erect setae. Region between torulus and eye concave. Area between the anterior margin of eyes and demarkation of median clypeal lobe 0.19 LH. Eye protuberant, 0.55 LH, with sparse hairs, located more laterally, lower margin without strong depression. Frons coriaceous-punctate. WH 0.93 LH. WF 0.6 WH. WF 1.0 HE. OOL 1.0 WOT. VOL 0.27 HE. Distance from posterior ocellus to vertex crest 1.0 DAO. Ocelli small, DAO 0.07 WF, ocellar triangle not compact, distance between posterior ocelli 4.0 DAO, anterior ocellus surpassing imaginary top eye line, posterior ocellus almost reaching vertex. Vertex straight, long setae, 0.30 LH, temple profile slightly convergent in dorsal view, with corner convex, not projected postero-laterad. Hipostomal carina straight, low.

Mesosoma ( Fig. 85 View FIGURES 84–92 ). Pronotal disc coriaceous-punctate, 0.74 as long as wide, anterior corner angulate, posterior margin concave medially, pronotal disc without short longitudinal furrow. Parapsidal furrow inconspicuous. Notauli convergent posterad. Mesoscutum 0.43 length pronotal disc. Scutellum coriaceouspunctate, 0.53 length pronotal disc, almost flat in profile, posterior margin convex medially, scutellar pit almost circular, dilated, distant each other 4.4 its own diameter. Dorsal axillar surface with fovea almost circular. Metanotum with median region high, coriaceous-puncticulate, as high as scutellum in profile, with fovea elliptical laterally. Propodeal disc wider than long; anterior margin without foveolate or transverse furrow; median carina 0.81 length propodeal disc, incomplete posterad; discal carina 0.18 length propodeal disc, parallel to median carina, straight; space between median and discal carina 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 present. Prosternum with median excavation complete, median suture present. Mesopectus with posterior depression composed by two large foveae almost fused; median suture evident.

Wings. Brachypterous. Forewing ( Fig. 130 View FIGURES 123–132 ) with 1M cell absent. C cell evenly narrow; 1R1 cell absent; 2R1 cell short, open; R1 b almost inconspicuous, but entirely on anterior margin of forewing; Rs+M vein 0.20 Rs a; M vein 0.75 Rs a; Rs a subperpendicular to anterior margin of forewing; Cu b absent; stigma rectangular; distal stigmal margin convex.

Legs. Profemur swollen, 0.4 as wide as long. Metacoxa with median region 0.48 as wide as long. Metacoxal projection in dorsal region conspicuous, apex rounded.

Metasoma. 0.32 as wide as long, except first two tergites, ventral carina of petiole present.

MALE. Unknown.

Material examined. Holotype ♀. AUSTRALIA, N[ew] S[outh] W[ales], Dorrigo NP, E and Blackbutt Track , 710 m, 28 ii–5 iii [19]80, subtrop[ical] rainf[orest], flight intercept window/ trough trap, A.Newton, M.Thayer, ANIC.

Distribution. Australia (New South Wales).

Remarks. This species is very different of the others by having the head subtriangular in profile, the median clypeal lobe truncate, with median carina, the parapsidal furrow absent, and mainly because it is brachypterous with forewing with Rs+M vein of forewing vestigial, 1R1 and 2R1 cells of forewing open, 1M cell of forewing absent.
