description: <i>Eupsenella dalla</i> Ramos &amp; Azevedo, sp. nov. (Figs 21, 66, 111) <b>Description.</b> FEMALE (holotype). Body length 6.14 mm. LFW 4.43 mm. <i>Coloration.</i> Head dark castaneous almost black; scape, pedicel and flagellum castaneous; mandible with body almost dark castaneous and only apex castaneous; palpi light castaneous; mesosoma dark castaneous almost black; tegula castaneous; wing venation dark castaneous; procoxa dark castaneous almost black; mesocoxa and metacoxa castaneous; trochanters light castaneous; profemur dark castaneous almost black; mesofemur and metafemur dark castaneous; tarsi light castaneous; metasoma dark castaneous. <i>Head</i> (Fig. 21). Head longer than wide, globoid in profile; gena without concavity in profile. Mandible with base wider than apex, teeth sub-equal, lower tooth curved inward, lower margin strongly setose. Clypeus coriaceous-punctate, median clypeal lobe subangulate, median concavity of median clypeal lobe absent, 0.09 LH, well marked off from frons, median carina present, 0.13 LH. Malar space inconspicuous, 0.15 mandibular base. Antenna 1.43 mm; first five antennomeres in ratio of about 8:9:9:9:9; flagellomere 1 1.29 longer than wide, flagellar pubescence dense, with many outstanding erect setae. Region between torulus and eye straight. Area between the anterior margin of eyes and demarkation of median clypeal lobe 0.11 LH. Eye not protuberant, 0.43 LH, with sparse hairs, located more laterally, lower margin without strong depression. Frons coriaceous-punctate. WH 0.92 LH. WF 0.59 WH. WF 1.3 HE. OOL 1.14 WOT. VOL 0.5 HE. Distance from posterior ocellus to vertex crest 0.5 DAO. Ocelli small, DAO 0.10 WF, ocellar triangle not compact, distance between posterior ocelli 3.5 DAO, anterior ocellus not surpassing imaginary top eye line, posterior ocellus almost reaching vertex. Vertex convex, long setae, 0.33 LH, temple profile slightly convergent in dorsal view, with corner convex, not projected postero-laterad. Hipostomal carina angulate, low. <i>Mesosoma</i> (Fig. 66). Pronotal disc coriaceous-punctate, 0.42 as long as wide, anterior corner angulate, posterior margin concave medially, pronotal disc without short longitudinal furrow. Parapsidal furrow conspicuous only at third posterior part, complete, parallel. Mesoscutum 0.92 length pronotal disc. Scutellum coriaceouspunctate, 0.75 length pronotal disc, almost flat in profile, posterior margin almost straight medially, scutellar pit elliptical, narrowed, distant each other 15.0 its own diameter. Dorsal axillar surface with fovea oval. Metanotum with median region almost flat, coriaceous-puncticulate, lower than scutellum in profile, with fovea oval laterally. Propodeal disc as long as wide; anterior margin without foveolate or transverse furrow; median carina 0.77 length propodeal disc, incomplete posterad, 0.38 length of propodeal disc; discal carina 0.29 length propodeal disc, parallel to median carina, straight; space between median and discal carina imbricate and confused-rugulose. Mesopleuron with subtegular furrow elliptical; mesepimeral suture almost inconspicuous posterad; mesopleural epicoxal lobe conspicuous. 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. <i>Wings.</i> Macropterous. Forewing (Fig. 111) 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 0.15 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> absent; Rs+M vein 1.3 Rs <i>a</i>; M vein 1.0 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 adjacent each other. <i>Legs.</i> Profemur very swollen, 0.67 as wide as long. Metacoxa with median region 0.5 as wide as long. Metacoxal projection in dorsal region conspicuous, apex sharpened. <i>Metasoma.</i> 4.3 as wide as long, ventral carina of petiole present. MALE. Unknown. <b>Material examined.</b> <i>Holotype</i> &amp;female;. AUSTRALIA, S[outh] A[ustralia], 33.40S 136.54E, 2 Km NE Cowell, 27 Nov [ember] 1992, I.D.Naumann &amp; J.C.Cardale, Malaise /ethanol, ANIC. <i>Paratype</i>. AUSTRALIA, W[estern] A[ustralia], 1 &amp;female;, 33.43S 119.45E, 22 Sept [ember] 1981, West R [oad] 30 Km SW by W.Ravensthorpe, I.D.Naumann &amp; J.C.Cardale, Malaise /ethanol, ANIC. <b>Distribution.</b> Australia (South Australia, Western Australia). <b>Remarks.</b> This species is similar to <i>E. diemenensis</i> by having the median clypeal lobe angulate, the notauli slightly convergent posterad, the propodeal disc confused-rugulose and the R1 <i>b</i> of forewing entirely on anterior margin of forewing. However this species has the head with vertex crest clearly convex, the propodeal disc with discal carina very short, almost inconspicuous and median carina short (less than half length disc), whereas <i>E. diemenensis</i> has the head with vertex crest slightly convex (almost straight), the propodeal disc with discal carina long (more than half length disc).
