Description

Female

MEASUREMENTS. Body length 5.9 mm; fore wing length 4.5 mm.

HEAD. Width 1.25 times its median length, 1.2 times width of mesoscutum. Head behind eyes (dorsal view) weakly roundly narrowed. Transverse diameter of eye 1.7 times length of temple. Ocelli rather small, arranged in triangle with base almost equal to its sides; POL 1.4 times OD, 0.6 times OOL. Eye 1.2 times as high as broad. Malar space 0.6 times height of eye, 1.15 times basal width of mandible. Face distinctly convex, its width 1.2 times height of eye and 1.6 times height of face and clypeus combined. Clypeus low, its upper margin situated distinctly below than lower level of eyes. Hypoclypeal depression round, its width 0.65 times distance from edge of depression to eye, 0.4 times width of face. Vertex weakly convex. Head below eyes distinctly and weakly-roundly narrowed. Antennae rather slender, almost filiform, more than 7-segmented (most part of segments missing). Scapus 2.0 times as long as its maximum width. First flagellar segment 6.5 times as long as its apical width, 1.25 times as long as second segment.

MESOSOMA. Length 2.5 times its height. Mesoscutum (dorsal view) as long as maximum width, its median lobe distinctly convex anteriorly. Notauli complete, entirely rugose-crenulate. Prescutellar depression rather shallow, long, distinctly and almost linearly oblique posterolaterally, entirely and rather densely reticulate-rugose with short striae, 0.4 times as long as scutellum. Sternaulus (precoxal furrow) weakly curved, almost entirely smooth. Prepectal carina belowe with weakly widened ventral lobes opposite fore coxae. Subalar depression coarsely longitudinally striate with granulation marginally.

WINGS. Fore wing 4.4 times its maximum width. Radial (marginal) cell 4.5 times as long as wide. Metacarpus (1-R1) 1.3 times as long as pterostigma. First radial abscissa (r) forming right angle with second abscissa (3-SR). Second radial abscissa (3-SR) weakly curved, 5.4 times as long as first abscissa (r), 1.8 times as long as almost straight third abscissa (SR1), 2.5 times as long as first radiomedial vein (2-SR). Second radiomedial (submarginal) cell long, weakly widened distally, 3.3 times as long as wide, 1.2 times as long as the narrow brachial (subdiscal) cell. First medial abscissa (1-SR+M) strongly sinuate. Recurrent vein (m-cu) 2.3 times as long as second median abscissa (2-SR+M), 0.6 times as long as first radiomedial vein (2-SR). Mediocubital vein (M+CU1) strongly curved to anal vein (2-1A) in distal third. Distance between nervulus (cu-a) and basal (1-M) vein 0.4 times nervulus (cu-a) length. Brachial (subdiscal) cell closed shortly behind level of recurrent vein; posterior bulla and posterior abscissa of anal vein (2-1A) (behind brachial vein (CU1b)) absent. Hind wing about 5.0 times as long as wide. Recurrent vein (m-cu) more or less sclerotised, pigmented.

LEGS. Fore femur about 4.0 times as long as wide. Hind coxa 1.5 times as long as wide, 0.75 times as long as propodeum. Hind femur 3.5 times as long as maximum width. Hind tibia with dense comb of rather long pale setae on inner apical margin. Hind tarsus as long as hind tibia. Second tarsal segment 0.4 times as long as basitarsus, 2.7 times as long as fourth segment, as long as fifth segment (without pretarsus).

METASOMA. Length about as long as head and mesosoma combined. First tergite almost entirely flat (lateral view), distinctly and linearly widened towards apex (dorsal view); maximum width of tergite 2.0 times its basal width; its length 1.75 times apical width, 1.35 times length of propodeum. Median length of second tergite 0.65 times its basal width, 0.9 times length of third tergite. Second suture very shallow, narrow, weakly evenly curved. Fifth and sixth tergite short, straight on posterior margins, without any median emargination and postero-ventral lobes. Ovipositor sheath very weakly widened towards subapex, then distinctly narrowed towards apex; about as long as metasoma, 1.4 times as long as mesosoma, 0.7 times as long as fore wing.

SCULPTURE AND PUBESCENCE. Vertex and frons entirely distinctly, densely and weakly sinuate striate; face densely and distinctly curvedly striate with rugulosity between striae in upper half; temple distinctly curvedly striate in upper half, sculpture becoming fine below and almost smooth in lower part. Mesoscutum and scutellum entirely densely granulate, mesoscutum with narrow rugose subtriangular area in its medioposterior half. Mesopleuron mostly longitudinally and partly curvedly striate, with reticulation postero-ventrally, almost smooth below sternaulus. Metapleuron distinctly and small rugosereticulate with granulation, partly with curved longitudinal striae. Propodeum very densely and small reticulate-areolate, posteriorly with additional rugosity. Hind coxa almost entirely densely and distinctly granulate. Hind femur entirely densely and distinctly reticulate-granulate becoming coriaceous in lower part. First, second and most part of third tergites entirely, very densely and small or very small reticulateareolate, without any striation, sculpture becoming finer to end of third tergite. Fourth to sixth tergites very densely and finely or very finely transverse aciculate and coriaceous. Vertex glabrous in anterior half, in sparse, short and semi-erect pale setae in posterior half. Mesoscutum mainly glabrous, with sparse and short semi-erect pale setae in anterolateral corners, along notauli and marginally. Mesopleuron widely glabrous. Hind tibia dorsally with rather long, sparse, semi-erect pale setae; length of these setae 0.6–0.8 times maximum width of hind tibia.

COLOUR. Head yellow to yellowish brown, with brown longitudinal and rather wide stripe on middle on vertex and frons, face mainly brown. Mesosoma mainly brownish yellow or yellow, mesonotum, lower part of meso- and metapleuron dark reddish brown to almost black. Metasoma reddish brown, second and most part of third tergites as well as sides of rest tergites yellow. Scapus and pedicel of antenna dark reddish brown, basal segments of antenna yellow to brownish yellow. Palps pale yellow. Legs mainly yellow or whitish yellow, middle and especially hind coxae, trochantelli partly, protuberances on femora, subbasal and apical wide stripes on hind tibia, most part of basitarsi and all fifth segments of tarsi brown to dark reddish brown; hind tibia pale yellow basally. Fore wing distinctly infuscate, with numerous small hyaline spots and stripes. Pterostigma brown, pale or whitish yellow in basal and apical 0.4 and along inner margin.

Male

Unknown.
