Coloration. Head dark castaneous almost black; scape and pedicel dark castaneous; flagellum castaneous; mandible dark castaneous; palpi castaneous; mesosoma dark castaneous almost black; tegula and wing venation castaneous; procoxa dark castaneous; mesocoxa, metacoxa and trochanters castaneous; profemur dark castaneous; mesofemur, metafemur and tarsi castaneous; metasoma dark castaneous.

Head ( Fig. 24 View FIGURES 15–26 ). Head wider than long, subtriangular in profile; gena without concavity 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 angulate, median concavity of median clypeal lobe absent, 0.06 LH, well marked off from frons, median carina present, 0.20 LH. Malar space conspicuous, 0.23 mandibular base. Antenna 2.38 mm; first five antennomeres in ratio of about 13:13:15:13:13; flagellomere 1 1.5 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, 0.72 LH, with sparse hairs, located more laterally, lower margin without strong depression. Frons coriaceous-punctate. WH 1.12 LH. WF 0.59 WH. WF 1.06 HE. OOL 0.67 WOT. VOL 0.25 HE. Distance from posterior ocellus to vertex crest 0.5 DAO. Ocelli large, DAO 0.12 WF, ocellar triangle not compact, distance between posterior ocelli 2.6 DAO, anterior ocellus surpassing imaginary top eye line, posterior ocellus almost reaching vertex. Vertex concave, long setae, 0.20 LH, temple profile approximately parallel in dorsal view, with corner angulate, slightly projected postero-laterad. Hipostomal carina straight, low.

Mesosoma ( Fig. 69 View FIGURES 66–74 ). Pronotal disc coriaceous-punctate, 0.42 as long as wide, anterior corner rounded, posterior margin concave medially, pronotal disc without short longitudinal furrow. Parapsidal furrow conspicuous only at third posterior part. Notauli convergent posterad. Mesoscutum 1.24 length pronotal disc. Scutellum coriaceous-punctate, 0.86 length pronotal disc, almost flat in profile, posterior margin convex medially, scutellar pit elliptical, dilated, distant each other 13.3 its own diameter. Dorsal axillar surface with fovea subrectangular. 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 0.73 length propodeal disc, incomplete posterad; discal carina 0.35 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 absent. Prosternum with median excavation complete, median suture present. Mesopectus with posterior depression heart-shaped; median suture evident.

Wings. Macropterous. Forewing ( Fig. 114 View FIGURES 113–122 ) with 1M cell subtriangular; 1M and 1R1 cells not aligned basally; C cell widening distally; 1R1 cell present, distinctly longer than 2R1 cell, evenly wide; Rs b straight; 2R1 cell 0.15 LFW. Rs c convex; r-rs vein inclined; R1 b entirely on anterior margin of forewing; Cu b absent; Rs+M vein 1.1 Rs a; M vein 1.14 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, 0.47 as wide as long. Metacoxa with median region 0.6 as wide as long. Metacoxal projection in dorsal region conspicuous, apex sharpened.

Metasoma. 0.33 as wide as long.

MALE. Unknown.

Distribution. Australia (Queensland, New South Wales).

Remarks. This species is similar to E. barada sp. nov. by having the head nearly subtriangular in profile, the eyes large, the pronotal disc without anterior median pit and apical margin nearly straight. However this species has the area between the anterior margin of eyes and demarkation of median clypeal lobe short, the eyes protuberant, the median clypeal lobe angulate, with median carina, whereas E. barada sp. nov. has the area between the anterior margin of eyes and demarkation of median clypeal lobe long, the median clypeal lobe truncate, without median carina.
