( Figures 21–31 View Figures 21–31 )
Type material
Holotype: female, ‘‘ Brunei: Bukit Sulans, nr. Lamunin, N.E. Stork’’ ( BMNH).
Description
Female. Body length 3.2 mm; fore wing length 2.3 mm.
Head width 1.4× its median length. Head behind eye (dorsal view) almost parallel-sided in anterior half, roundly narrowed in posterior half; transverse diameter of eye about twice as long as temple ( Figure 22 View Figures 21–31 ). Ocelli small, in triangle with base 1.4× its sides. POL 2× Od, 0.8× OOL. Eye glabrous, 1.15× as high as broad. Malar space height 0.4× height of eye, 0.8× basal width of mandible ( Figure 23 View Figures 21–31 ). Face width 0.9× height of eye and 1.1× height of face and clypeus combined. Clypeus with narrow lower flange. Clypeal suture distinct and complete. Hypoclypeal depression round, its width 0.7× distance from edge of depression to eye, 0.35× width of face ( Figure 21 View Figures 21–31 ). Hypostomal flange narrow. Antennae ( Figure 24 View Figures 21–31 ) slender, filiform, 29-segmented, 1.2× as long as body. Scapus 1.3× as long as its maximum width. First flagellar segment weakly curved outside, not flattened, 5.5× as long as its apical width, 0.9× as long as second segment. Penultimate segment 4.3× as long as its width, 0.7× as long as first flagellar segment, almost equal to apical segment; the latter pointed apically.
Mesosoma . Length 2.2× its height. Mesoscutum rather highly and perpendicularly raised above pronotum. Pronotal keel rather distinct. Notauli deep in anterior half, shallow in posterior half, crenulate-granulate. Prescutellar depression rather shallow, with three carinae, coriaceous, 0.3× as long as weakly convex scutellum. Subalar depression shallow, wide, striate-rugulose. Sternauli rather shallow, but deep medially, weakly curved, narrow, coriaceous, connected with prepectal carina anteriorly, running along almost entire length of lower part of mesopleura. Metapleural flange rather long, wide, rounded apically.
Wings. Fore wing ( Figure 25 View Figures 21–31 ) 4.5× as long as its maximum width. Radial vein arising weakly a little middle of pterostigma. Metacarpus 1.2× as long as pterostigma. Second radial abscissa 2.8× first abscissa, 0.5× the straight third abscissa, 1.3× first radiomedial vein. Second radiomedial cell almost 3.0× as long as its maximum width, 1.5× as long as brachial cell. First abscissa of medial vein almost straight. Recurrent vein 3.0× second abscissa of medial vein. Distance from nervulus to basal vein almost equal to nervulus length. Brachial cell closed apically distinctly before recurrent vein. Hind wing ( Figure 26 View Figures 21–31 ) 6.0× as long as wide. First abscissa of costal vein 0.5× second abscissa. First abscissa of mediocubital vein 0.4× second abscissa. Recurrent vein rather long, curved toward base of wing, unsclerotized, distinctly antefurcal.
Legs. Hind coxa without basoventral tooth, its length 1.7× maximum width ( Figure 28 View Figures 21–31 ). Hind femur almost 3.0× as long as wide ( Figure 29 View Figures 21–31 ). Hind tibia with four short and thick spines on apical outside margin ( Figure 27 View Figures 21–31 ). Hind tarsus almost as long as hind tibia. Basitarsus thickened, 0.5× as long as second to fifth segments combined. Second tarsal segment 0.65× as long as basitarsus, 1.3–1.5× as long as fifth segment (without pretarsus).
Metasoma. Metasoma ( Figure 31 View Figures 21–31 ) 1.5× as long as head and mesosoma combined. First tergite distinctly and almost linearly widened from base to apex ( Figure 31 View Figures 21–31 ), with long and rather thick spiracular tubercles in basal 0.3 that are directed somewhat downwards. Acrosternite of first tergite about 0.5× as long as tergite. Maximum width of first tergite about 2× its minimum width; length 1.8× its apical width. Second tergite with rather deep, straight, distinctly carinate, strongly posteriorly convergent lateral longitudinal light furrows; basal width of median area 3× its apical width; length of tergite 1.3× its basal width, 1.3× length of third tergite. Second suture very shallow medially and deep laterally, with weak lateral bends. Ovipositor sheath 0.8× as long as body, 1.4× as long as metasoma, 1.2× as long as fore wing.
Sculpture and pubescence. Vertex and frons finely and densely transversely striate with dense granulation. Face coarsely transversely striate with fine granulation between striae. Temple finely and densely transversely striate-coriaceous, smooth below. Mesoscutum densely rugulose-granulate, widely rugose in medioposterior 0.7. Scutellum finely granulatecoriaceous. Mesopleura densely granulate with rugosity, very finely coriaceous below sternauli. Metapleura entirely coarsely rugulose-areolate. Propodeum densely ruguloseareolate with granulation, sparsely striate posteriorly, without carina and marginate areas. Hind coxae granulate, transversely striate with dense granulation dorsally, finely coriaceous ventrally. Hind femur finely and densely granulate in upper half, coriaceous in below half. Hind tibia densely granulate. First and second tergites entirely densely striate, with rugulosity between striae. Third tergite densely granulate-coriaceous, with fine striation medially; smooth in medioposterior 0.75 and lateroposterior 0.2. Remaining tergites smooth. Mesoscutum entirely with dense short semi-erect hairs. Hind tibia with long, rather sparse and semi-erect hairs dorsally, length of these hairs 0.8–1.3× maximum width of hind tibia.
Colour. Body yellowish brown, head and apex of metasoma yellow. Antenna yellow in basal 0.2, distinctly infuscated toward apex. Palpi yellow. Tegulae brownish yellow. Legs brownish yellow, tarsi yellow, fifth tarsal segments brown. Ovipositor sheath brown. Fore wings faintly infuscate. Pterostigma brown, yellow in basal 0.4 and apically.
Male. Unknown.
Discussion
This new species is similar to E. hoabinicus sp. nov. but differs in the lateral furrows of second tergite being distinctly carinate and strongly posteriorly convergent ( Figure 31 View Figures 21–31 cf. Figure 76 View Figures 66–76 ), the relatively greater postocellar distance ( Figure 22 View Figures 21–31 cf. Figure 67 View Figures 66–76 ), the relatively narrow fore wing ( Figure 25 View Figures 21–31 cf. Figure 70 View Figures 66–76 ), the long dorsal hairs of the hind tibia ( Figure 27 View Figures 21–31 cf. Figure 74 View Figures 66–76 ), and the finely sculptured scutellum.
