 Head (Fig. 12). Head as long as wide, globoid in profile; gena without concavity in profile. Mandible with base wider than apex, lowermost tooth larger than upper ones, lower tooth curved inward, lower margin weakly setose. Clypeus coriaceous, median clypeal lobe angulate, median concavity of median clypeal lobe absent, 0.10 LH, well marked off from frons, median carina present, 0.14 LH. Malar space inconspicuous, 0.15 mandibular base. Antenna 1.86 mm; first five antennomeres in ratio of about 11:11:13:14:15; flagellomere 1 1.3 longer than wide, flagellar pubescence sparse, with few outstanding erect setae. Region between torulus and eye slightly concave. Area between the anterior margin of eyes and demarkation of median clypeal lobe 0.18 LH. Eye not protuberant, 0.47 LH, with sparse hairs, located more laterally, lower margin without strong depression. Frons coriaceouspunctate. WH 1.0 LH. WF 0.67 WH. WF 0.67 HE. OOL 0.86 WOT. VOL 0.22 HE. Distance from posterior ocellus to vertex crest 0.33 DAO. Ocelli large, DAO 0.14 WF, ocellar triangle not compact, distance between posterior ocelli 4.6 DAO, anterior ocellus not surpassing imaginary top eye line, posterior ocellus almost reaching vertex. Vertex straight, long setae, 0.24 LH, temple profile slightly convergent in dorsal view, with corner convex, not projected postero-laterad. Hipostomal carina angulate, low.   
 Mesosoma (Fig. 57). Pronotal disc coriaceous-punctate, 0.33 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 1.8 length pronotal disc. Scutellum coriaceous, 1.33 length pronotal disc, almost flat in profile, posterior margin convex medially, scutellar pit elliptical, narrowed, distant each other 7.0 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 0.90 length propodeal disc, incomplete posterad; discal carina 0.38 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 present. Prosternum with median excavation complete, median suture present. Mesopectus with posterior depression heart-shaped; median suture evident.   
 Wings. Macropterous. Forewing (Fig. 102) with 1M cell subpentagonal; 1M and 1R1 cells aligned basally; C cell widening distally; 1R1 cell present, slightly longer than 2R1 cell, evenly wide; Rs b straight; 2R1 cell 0.19 LFW; distal margin of Rs c angulate; r-rs vein inclined; R1 b entirely on anterior margin of forewing; Cu b absent; Rs+M vein 0.73 Rs a; M vein 1.43 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, 0.4 as wide as long. Metacoxa with median region 0.55 as wide as long. Metacoxal projection in dorsal region conspicuous, apex rounded.   
 Metasoma. 0.22 as wide as long, with few setae, ventral carina of petiole present. Hypopygium (Fig. 142) with without concavity, inner margin of ventral arm angulate medially in lateral view; basiparamere with apical margin not angulate medially; volsella aligned with aedeagus apex; cuspis 0.50 length of apical lobe of aedeagus, 1.23 width of apical lobe of aedeagus; digitus 0.25 length of apical lobe of aedeagus, upper surface not spinose; aedeagus with median region as wide as base; apical lobe 0.38 aedeagus length, fold of inner margin absent; apex straight.   
FEMALE. Unknown.  
 Material examined. Holotype ♂. AUSTRALIA, N[ew] S[outh] W[ales], Wiamgaree S [tate] For [est], 1050 m, Isakson Ridge, 29 Feb [ruary]–3 Mar [ch] 1980, A.Newton & M.Thayer Northo. moorei, rainf[orest], flight intercept / window trough trap, ANIC.   
 Distribution. Australia (New South Wales).   
 Remarks. This species is similar to E. insulana by having the median clypeal lobe angulate, the median carina of propodeal disc present, the hind wing with four distal hamuli, the posterior margin of hypopygium angulate, but it differs from it by having the median carina of propodeal disc short the ventral arm with inner margin clearly angulate, whereas E. insulana has the median carina of propodeal disc long, the ventral arm of genitalia without inner margin clearly angulate.   
 It is also similar to E. ajabatha sp. nov. because both species present the eyes small, the ocelli large, the median carina of median clypeal lobe strongly elevated, the median carina of propodeal disc long, the posterior margin of hypopygium angulate and the genitalia with paramere doble. However this species has the vertex crest of head straight, the region between the anterior margin of eye and antennal torulus concave, the area between the anterior margin of eyes and demarkation of median clypeal lobe long, the Rs c of forewing angulate medially, the lateral stalk of hypopigium very short, almost inconspicuous and the parameres of genitalia short, whereas E. ajabatha sp. nov. has the vertex crest of head convex, the region between the anterior margin of eye and antennal torulus straight, the area between the anterior margin of eyes and demarkation of median clypeal lobe short, the Rs c of forewing convex, the lateral stalk of hypopigium long and the paramere of genitalia short.
