Eupsenella pangkala Ramos & Azevedo , sp. nov.

( Figs 45 View FIGURES 39–47 , 90 View FIGURES 84–92 , 135 View FIGURES 133–137 )

Description. FEMALE (holotype). Body length 5.05 mm. LFW 3.57 mm.

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

Head ( Fig. 45 View FIGURES 39–47 ). Head wider than long, subrectangular in profile; gena weakly concave in profile. Mandible evenly wide, teeth sub-equal, lower tooth curved inward, lower margin strongly setose. Clypeus coriaceous, median clypeal lobe subangulate, median concavity of median clypeal lobe absent, 0.10 LH, well marked off from frons, median carina absent. Malar space inconspicuous, very short, almost touching lower margin of eye, 0.09 mandibular base. Antenna 1.48 mm; first five antennomeres in ratio of about 9:9:9:9:9; flagellomere 1 1.3 longer than wide, flagellar pubescence dense, with many outstanding erect setae. Region between torulus and eye concave. Area between the anterior margin of eyes and demarkation of median clypeal lobe 0.05 LH. Eye protuberant, 0.48 LH, with sparse hairs, located more laterally, lower margin without strong depression. Frons coriaceous-punctate. WH 1.1 LH. WF 0.57 WH. WF 1.18 HE. OOL 0.88 WOT. VOL 0.46 HE. Distance from posterior ocellus to vertex crest 1.0 DAO. Ocelli large, DAO 0.11 WF, ocellar triangle not compact, distance between posterior ocelli 3.6 DAO, anterior ocellus not surpassing imaginary top eye line, posterior ocellus almost reaching vertex. Vertex convex, long setae, 0.29 LH, temple profile slightly convergent in dorsal view, with corner convex, not projected postero-laterad. Hipostomal carina slightly arched, high.

Mesosoma ( Fig. 90 View FIGURES 84–92 ). Pronotal collar strongly short, almost absent, evenly narrow. Pronotal disc coriaceouspunctate, short, 0.36 as long as wide, anterior corner rounded, posterior margin concave medially, pronotal disc without short longitudinal furrow. Parapsidal furrow inconspicuous. Notauli parallel to each other. Mesoscutum 1.63 length pronotal disc. Scutellum coriaceous, 1.25 length pronotal disc, convex in profile, posterior margin convex medially, scutellar pit elliptical, narrowed, distant each other 12.0 its own diameter. Dorsal axillar surface with fovea oval. Metanotum with median region almost flat, foveolate, lower than scutellum in profile, with fovea oval laterally. Propodeal disc wider than long; anterior margin without foveolate or transverse furrow; posterior region slightly elevated, smooth and continuous to median carina; median carina 0.17 length propodeal disc, incomplete posterad; discal carina 0.09 length propodeal disc, converging posterad, slightly arched; space between median and discal carina 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 restricted to posterior region, median suture present. Mesopectus with posterior depression composed by two large foveae almost fused; median suture not evident.

Wings. Macropterous. Forewing ( Fig. 135 View FIGURES 133–137 ) with 1M cell absent, closed, subpentagonal; 1M and 1R1 cells not aligned basally; C cell evenly narrow;1R1 cell present, distinctly longer than 2R1 cell, evenly wide; Rs b straight; 2R1 cell 0.15 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 1.1 Rs a; M vein 1.17 Rs a; Rs a slightly inclined toward tegula; stigma rectangular; distal stigmal margin truncate. Hind wing with five distal hamuli, last hamulus discontinuous each other.

Legs. Profemur swollen, 0.5 as wide as long. Metacoxa with median region 0.5 as wide as long. Metacoxal projection in dorsal region conspicuous, apex rounded.

Metasoma. 0.22 as wide as long, weakly coriaceous shining, ventral carina of petiole present.

MALE. Unknown.

Material examined. Holotype ♀. AUSTRALIA, S[outh] A[ustralia], Parachilna C [ree]k, 8 Nov[ember] 1987, I.D.Naumann, J.C.Cardale, ex[tracted] ethanol, ANIC . Paratypes. AUSTRALIA, S[outh] A[ustralia], 1 ♀, Parachilna

Distribution. Australia (South Australia).

Variation. Body length 4.76–5.23 mm; LFW 3.33–3.57 mm; notauli almost parallel, vertex slightly convex, legs can be lighter.

Remarks. This species is similar to E. flavifemorata by having the mesoscutum large and the legs light castaneous. However this species has the malar space almost inconspicuous, malar space almost touching lower margin of eye, the vertex crest strongly convex, the pronotal disc with anterior convex, narrow, the posterior margin of scutellum almost straight, the median carina of propodeal disc narrowing towards posterad, whereas E. flavifemorata has the malar space clearly conspicuous, malar clearly not touching lower margin of eye, the vertex crest slightly convex, the pronotal disc with anterior almost straight, wide, the posterior margin of scutellum convex, the median carina of propodeal disc evenly wide.
