Scutellum coriaceouspunctate, 1.12 length pronotal disc, almost flat in profile, posterior margin convex medially, scutellar pit elliptical, narrowed, distant each other 9.33 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 0.83 length propodeal disc, complete posterad; discal carina 0.16 length propodeal disc, converging posterad, straight; space between median and discal carina confused-rugulose. Mesopleuron with subtegular furrow oval; mesepimeral suture wholly conspicuous; 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 not evident. <i>Wings.</i> Macropterous. Forewing (Fig. 99) with 1M cell subpentagonal; 1M and 1R1 cells not aligned basally; C cell widening distally; 1R1 cell present, distinctly longer than 2R1 cell, evenly wide; Rs <i>b</i> straight; 2R1 cell 0.16 LFW; distal margin of Rs <i>c</i> convex; r-rs vein inclined; R1 <i>b</i> entirely on anterior margin of forewing; Cu <i>b</i> present; Rs+M vein 1.2 Rs <i>a</i>; M vein 2.0 Rs <i>a</i>; Rs <i>a</i> slightly inclined toward tegula; stigma rectangular; distal stigmal margin truncate. Hind wing with four distal hamuli, last hamulus discontinuous each other. <i>Legs.</i> Profemur swollen, 0.43 as wide as long. Metacoxa with median region 0.67 as wide as long. Metacoxal projection in dorsal region conspicuous, apex sharpened. <i>Metasoma.</i> 0.36 as wide as long. Hypopygium (Fig. 139) with posterior margin weakly angulate; teeth of posterior margin straight, teeth distant each other, almost evenly thick; lateral stalk present and long. Genitalia (Figs 148–150) with paramere doble, apical margin in lateral view without concavity, inner margin of ventral arm not angulate in lateral view; basiparamere with apical margin slightly angulate medially; volsella not surpassing aedeagus apex; cuspis 0.54 length of apical lobe of aedeagus, 1.84 width of apical lobe of aedeagus; digitus 0.92 length of apical lobe of aedeagus, upper surface spinose; aedeagus with median region wider than base; apical lobe 0.43 aedeagus length, fold of inner margin present; apex straight. FEMALE. Unknown. <b>Material examined.</b> <i>Holotype</i> &amp;male;. AUSTRALIA, Tas [mania], 43.22S 146.09, Celery Top I [sland]s, Bathurst Harbour, 12–17 Feb [ruary] 1990, I.D.Naumann, rainforest, ANIC. <i>Paratypes</i>. AUSTRALIA, N[ew] S[outh] W[ales], 1 &amp;male;, Clyde M [ountain], lands lip, 5 May, 1965, D.H.Colless, ANIC; Tas [mania], 1 &amp;male;, 41.16S 145.37E, Hellyer George, 1 Feb [ruary] 1983, I.D.Naumann &amp; J.C.Cardale, ex[tracted] ethanol, ANIC; 43.22S 146.08E, 1 &amp;male;, Claytons, Bathurst Harbour 3 Dec [ember] 1990–15 Jan [uary] 1991, Nielsen, Edwards, Malaise trap, ANIC. <b>Distribution.</b> Australia (Tasmania, New South Wales). <b>Variation.</b> Body length 4.29–5.48 mm; LFW 3.90–4.30 mm; median clypeal lobe slightly projected, vertex crest almost straight. <b>Remarks.</b> This species is similar to <i>E. insulana</i> by having the median clypeal lobe angulate, the discal carina and median carina of propodeal disc present, the hind wing with four distal hamuli, the posterior margin of hypopygium angulate and the lateral stalk of hypopygium conspicuous, but it differs from it by having the apical margin of digitus spinose, the posterior margin of hypopygium with teeth wide and one distant from the other, whereas <i>E. insulana</i> has the apical margin of digitus not spinose, the posterior margin of hypopygium very close to each other. It is also similar to <i>E. antakirinja</i> <b>sp. nov.</b> because both species have 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 slightly 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 <i>c</i> of forewing convex, the lateral stalk of hypopigium long, the parameres of genitalia long, whereas <i>E. antakirinja</i> <b>sp. nov.</b> 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 <i>c</i> of forewing angulate medially, the lateral stalk of hypopigium very short, almost inconspicuous and the parameres of genitalia short.
