Scutellum coriaceous-punctate, 1.05 length pronotal disc, almost flat in profile, posterior margin convex medially, scutellar pit elliptical, dilated, distant each other 10.0 its own diameter. Dorsal axillar surface with fovea furrow; median carina 0.90 length propodeal disc, incomplete posterad; discal carina absent; disc predominantly slightly 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. 103 ) with 1M cell subpentagonal; 1M and first 1R1 cells not aligned basally; C cell widening distally; 1R1 present, distinctly longer than 2R1 cell, evenly wide; Rs b convex; 2R1 cell 0.12 LFW; distal margin of Rs c convex; r-rs vein inclined; R1 b entirely on anterior margin of forewing; Cu b absent; Rs+M vein 1.0 Rs a; M vein 1.66 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 swollen, 0.46 as wide as long. Metacoxa with median region 0.48 as wide as long. Metacoxal projection in dorsal region conspicuous, apex sharpened.

Metasoma. 0.3 as wide as long. Hypopygium ( Fig. 143 ) with posterior margin strongly angulate; teeth of posterior margin straight, teeth distant each other, narrowing apicad; lateral stalk present, but almost vestigial. Genitalia ( Figs 160–162 ) with paramere doble, apical margin in lateral view without concavity, inner margin of ventral arm angulate basally in lateral view; basiparamere with apical margin not angulate; volsella aligned with aedeagus apex; cuspis 0.40 length of apical lobe of aedeagus, 2.20 width of apical lobe of aedeagus; digitus 0.38 length of apical lobe of aedeagus, upper surface not spinose; aedeagus with median region as wide as base; apical lobe 0.47 aedeagus length, fold of inner margin absent; apex straight.

FEMALE. Unknown.

Material examined. Holotype ♂. AUSTRALIA, Tas [mania], 42.04S 148.13E, 14 km ESE Cranbrook, 28 Jan [uary] 1983, I.D.Naumann & J.C.Cardale, ex[tracted] ethanol, ANIC.

Distribution. Australia (Tasmania).

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, the Rs b of forewing slightly convex, the apical lobe of aedeagus large. However this species has the propodeal disc with discal carina absent, the digitus not spinose, the C cell of forewing conspicuous almost at all extension of C cell, the teeth of posterior margin of hypopygium clearly narrowing strongly toward apex, the teeth of posterior margin of hypopygium distant from each other, the lateral stalk of hypopygium almost inconspicuous, the apical lobe of aedeagus with fold in the inner margin absent, whereas E. insulana has the propodeal disc with discal carina present, but short, the digitus spinose, the C cell of forewing conspicuous only distally, the teeth of posterior margin of hypopygium evenly wide, the digitus spinose, the teeth of posterior margin of hypopygium evenly wide, close to each other, the lateral stalk of hypopygium long, the apical lobe of aedeagus with fold in the inner margin present.
