description: <i>Eupsenella nanda</i> Ramos &amp; Azevedo, sp. nov. (Figs 43, 88, 133) <b>Description.</b> FEMALE (holotype). Body length 7.15 mm. LFW 4.52 mm. <i>Coloration.</i> Head dark castaneous almost black; scape, pedicel and flagellum castaneous; mandible light castaneous with teeth dark castaneous; palpi light castaneous; mesosoma dark castaneous almost black; tegula castaneous; wing venation light castaneous; coxae, trochanters, femora and tarsi castaneous; metasoma dark castaneous with light castaneous portions along its length. <i>Head</i> (Fig. 43). Head as long as wide, globoid in profile; gena weakly concave in profile. Mandible with base wider than apex, two lowermost teeth larger than upper ones, lower tooth curved inward, lower margin strongly setose. Clypeus coriaceous-punctate, median clypeal lobe subangulate, median concavity of median clypeal lobe absent, 0.08 LH, well marked off from frons, median carina present, 0.1 LH. Malar space conspicuous, 0.32 mandibular base. Antenna 1.71 mm; first five antennomeres in ratio of about 9:10:10:10:10; flagellomere 1 1.11 longer than wide, flagellar pubescence dense, 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 0.08 LH. Eye not protuberant, 0.44 LH, with sparse hairs, located more laterally, lower margin without strong depression. Frons coriaceous-punctate. WH 1.0 LH. WF 0.66 WH. WF 0.66 HE. OOL 1.33 WOT. VOL 1.11 HE. Distance from posterior ocellus to vertex crest 1.0 DAO. Ocelli large, DAO 0.12 WF, ocellar triangle not compact, distance between posterior ocelli 2.2 DAO, anterior ocellus not surpassing imaginary top eye line, posterior ocellus distant from vertex. Vertex straight, short setae, 0.15 LH, temple profile approximately parallel in dorsal view, with corner convex, not projected postero-laterad. Hipostomal carina sinuous, low. <i>Mesosoma</i> (Fig. 88). Pronotal disc coriaceous-punctate, 0.41 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 1.25 length pronotal disc. Scutellum coriaceous-punctate, 1.0 length pronotal disc, almost flat in profile, posterior margin convex medially, scutellar pit elliptical, narrowed, distant each other 13.3 its own diameter. Dorsal axillar surface with fovea subrectangular. 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 0.97 length propodeal disc, complete posterad, located within a shallow median furrow; discal carina 0.17 length propodeal disc, converging posterad, slightly arched; 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 composed by two large foveae almost fused; median suture not evident. <i>Wings.</i> Macropterous. Forewing (Fig. 133) 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 0.86 Rs <i>a</i>; M vein 0.82 Rsa; Rs <i>a</i> slightly inclined toward tegula; stigma rectangular; distal stigmal margin truncate. Hind wing with seven distal hamuli, last hamulus adjacent each other. <i>Legs.</i> Profemur swollen, 0.54 as wide as long. Metacoxa with median region 0.56 as wide as long. Metacoxal projection in dorsal region conspicuous, apex sharpened. <i>Metasoma.</i> 0.29 as wide as long, ventral carina of petiole present. MALE. Unknown. <b>Material examined.</b> <i>Holotype</i> &amp;female;. AUSTRALIA, N[orthern] T[erritory], 23.46S 133.04E, Ellery Gorge, 85 Km W of Alice Springs, 5 Nov [ember] 1979, I.D.Naumann, ANIC. <b>Distribution.</b> Australia (Northern Territory). <b>Remarks.</b> This species is very different of the others by having the median clypeal lobe subangulate, the posterior margin of pronotal disc sinuous, the median carina of propodeal disc long and bordered by furrow, and the Rs <i>b</i> of forewing almost aligned with Cu <i>a</i>.
