Region between torulus and eye concave. Area between the anterior margin of eyes and demarkation of median clypeal lobe 0.12 LH. Eye not protuberant, 0.44 LH, with sparse hairs, located more laterally, lower margin without strong depression. Frons coriaceous-punctate. WH 1.14 LH. WF 0.6 WH. WF 1.37 HE. OOL 1.0 WOT.

Ocelli large, DAO 0.11 WF, ocellar triangle not compact, distance between posterior ocelli 4.4 DAO, anterior ocellus not surpassing imaginary top eye line, posterior ocellus almost reaching vertex. Vertex straight, long setae, 0.23 LH, temple profile slightly convergent in dorsal view, with corner convex, not projected posterolaterad. Hipostomal carina arched, high.

Mesosoma (Fig. 55). Pronotal disc coriaceous-punctate, 0.37 as long as wide, anterior corner rounded, posterior margin concave medially, pronotal disc with short longitudinal furrow. Parapsidal furrow inconspicuous. Notauli convergent posterad. Mesoscutum 1.2 length pronotal disc. Scutellum coriaceous-punctate, 0.95 length pronotal disc, almost flat in profile, posterior margin convex medially, scutellar pit elliptical, dilated, distant each other 9.0 its own diameter. Dorsal axillar surface with fovea almost circular. Metanotum with median region almost flat, foveolate, lower than 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 0.19 length propodeal disc, converging posterad, straight; space between median and discal carina confused-rugulose. Mesopleuron with subtegular furrow oval; 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. 100 ) with 1M cell subtriangular; 1M and 1R1 cells aligned basally; C cell widening distally; 1R1 cell present, distinctly longer than 2R1 cell, evenly wide; Rs b straight; 2R1 cell 0.18 LFW; distal margin of Rs c strongly convex; r-rs vein inclined; R1 b arching distally; Cu b present; Rs+M 1.2 Rs a; M vein 1.25 Rs a; Rs a slightly inclined toward tegula; stigma rectangular; distal stigmal margin truncate. Hind wing with five distal hamuli, last hamulus discontinuous each other.

Legs. Profemur swollen, 0.34 as wide as long. Metacoxa with median region 0.4 as wide as long. Metacoxal projection in dorsal region conspicuous, apex rounded.

Metasoma. 0.34 as wide as long. Hypopygium ( Fig. 140 ) with posterior margin strongly angulate; teeth of posterior margin arched, teeth distant each other, narrowing apicad; lateral stalk present, but almost vestigial. Genitalia ( Figs 151–153 ) with paramere doble, apical margin in lateral view without concavity, inner margin of ventral arm not angulate in lateral view; basiparamere with apical margin strongly angulate medially; volsella aligned with aedeagus apex; cuspis 0.45 length of apical lobe of aedeagus, 1.1 width of apical lobe of aedeagus; digitus 0.35 length of apical lobe of aedeagus, upper surface not spinose; aedeagus with median region wider than base; apical lobe 0.43 aedeagus length, fold of inner margin present; apex straight.

FEMALE. Unknown.

Material examined. Holotype ♂. AUSTRALIA, N[ew] S[outh] W[ales], Royalla, Mar[ch] 1961, D.H.Colless, ANIC.

Distribution. Australia (New South Wales).

Remarks. This species is similar to E. insulana by having the discal carina and median carina of propodeal disc present, the hind wing with four distal hamuli, the posterior margin of hypopygium angulate. However this species has the median clypeal lobe truncate, the median clypeal lobe with median carina absent, the aedeagus wider medially, whereas E. insulana has the median clypeal lobe angulate, the median clypeal lobe with median
