( Figs 44 View FIGURES 39–47 , 89 View FIGURES 84–92 , 134 View FIGURES 133–137 )

Description. FEMALE (holotype). Body length 8.81 mm. LFW 4.77 mm.

Coloration. Head dark castaneous almost black; scape, pedicel, flagellum and mandible dark castaneous; palpi castaneous; mesosoma dark castaneous almost black; tegula castaneous; wing venation dark castaneous; coxae dark castaneous; trochanters castaneous; femora dark castaneous; tarsi castaneous; metasoma dark castaneous almost black.

Head ( Fig. 44 View FIGURES 39–47 ). Head wider than long, subrectangular in profile; gena weakly concave in profile. Mandible with base wider than apex, lowermost tooth larger than upper ones, lower tooth curved outward, lower margin strongly setose. Clypeus coriaceous, median clypeal lobe broadly rounded, median concavity of median clypeal lobe absent, 0.20 LH, badly marked off from frons, resembling the projection of frons, median carina absent. Malar space conspicuous, very large, 1.0 mandibular base. Antenna 2.48 mm; first five antennomeres in ratio of about 15:15:15:14:13; flagellomere 1 1.37 longer than wide, flagellar pubescence dense, with few outstanding erect setae. Region between torulus and eye angulate medially. Area between the anterior margin of eyes and demarkation of median clypeal lobe 0.17 LH. Eye protuberant, 0.46 LH, with sparse hairs, located more laterally, lower margin with strong depression. Frons coriaceous-punctate. WH 1.28 LH. WF 0.65 WH. WF 1.95 HE. OOL 1.3 WOT. VOL 0.53 HE. Distance from posterior ocellus to vertex crest 0.5 DAO. Ocelli very small, DAO 0.03 WF, ocellar triangle not compact, distance between posterior ocelli 5.0 DAO, anterior ocellus surpassing imaginary top eye line, posterior ocellus almost reaching vertex. Vertex strongly concave, short setae, 0.13 LH, temple profile slightly convergent in dorsal view, with corner angulate, slightly projected postero-laterad. Hipostomal carina arched, low.

Mesosoma ( Fig. 89 View FIGURES 84–92 ). Pronotal disc polished, 0.64 as long as wide, anterior corner rounded, posterior margin concave medially, pronotal disc without short longitudinal furrow. Parapsidal furrow wholly conspicuous. Notauli convergent posterad. Mesoscutum 0.70 length pronotal disc. Scutellum coriaceous-punctate, 0.66 length pronotal disc, almost flat in profile, posterior margin convex medially, scutellar pit elliptical, narrowed, distant each other 11.0 its own diameter. Dorsal axillar surface with fovea oval. Metanotum with median region almost flat, foveolate, lower than scutellum in profile, with fovea elliptical laterally. Propodeal disc wider than long, anterior margin of propodeal disc with a foveolate transverse furrow, dilated ends; median carina 0.68 length propodeal disc, incomplete posterad, located within a median furrow; discal carina 0.3 length propodeal disc, parallel to median carina, straight; space between median and discal carina almost polished and smooth. Almost polished and smooth. 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. 134 View FIGURES 133–137 ) with 1M cell subpentagonal; 1M and 1R1 cells not aligned basally; C cell evenly narrow; 1R1 present, distinctly longer than 2R1 cell, evenly wide; Rs b straight; Cu b present; 2R1 cell 0.15 LFW; distal margin of Rs c convex; r-rs vein almost vertical; R1 b arching distally; Rs+M vein 0.85 Rs a; M vein 1.0 Rs a; Rs a slightly inclined toward tegula; stigma rectangular; distal stigmal margin truncate. Hind wing with four distal hamuli, last hamulus discontinuous each other.

Legs. Profemur very swollen, 0.69 as wide as long. Metacoxa with median region 0.46 as wide as long. Metacoxal projection in dorsal region conspicuous, apex rounded.

Metasoma. 0.33 as wide as long, weakly coriaceous shining, ventral carina of petiole present.

MALE. Unknown.

Distribution. Australia (Australian Capital Territory, New South Wales).

Remarks. This species is to E. ceciliae by having the vertex concave and ocelli small. However this species inconspicuous,whereas E. ceciliae has the vertex slightly concave, the region between anterior margin of eye and antennal torulus concave, the median carina of propodeal disc long, the forewing with Cu b absent and C cell conspicuous almost by all extension.
