Diagnosis.

As for genus.

Description.

Body rather depressed, elongate, poorly pubescent (length 5.35 mm). - Head prognathous, longer than wide; LH: 1.04 mm, WH: ca. 0.70 mm, HE: 0.60 mm, VOL: 0.20 mm; frons flat, punctate; compound eye elliptical, longer than high, not covering head length, located on anterior half of head, closer to mandible than to occipital carina; clypeus with median lobe rather projecting forward, lateral lobe poorly developed; mandible long, with three teeth, apical tooth longest; antenna filiform; scape 2.17 times as long as pedicel (length 0.26 mm); flagellomeres 1-10 cylindrical, all longer than wide (length 0.09-0.10 mm); flagellomere 11 longest, tapering at apex: ocelli forming short triangle, anterior ocellus not crossing supra-ocular line; occipital carina present, complete, forming weak arch. - Mesosoma flattened, with dorsum smooth (length 1.62 mm); propleuron slightly visible in dorsal view, ‘neck-shaped’; dorsal pronotal area 1.56 times as long as anteromesoscutum (length 0.50 mm), narrow, anterior flange developed, lateral margin slightly incurved, posterior margin concave; anteromesocutum wider than dorsal pronotal area, posterior margin straight; notaulus deeply impressed, not reaching posterior margin of anteromesoscutum, convergent; parapsidal signum poorly marked; mesoscuto-mesoscutellar suture with reniform sulcus connecting lateral foveae; mesoscutellum subquadrate, posterior margin slightly convex; metanotum rather developed, overlapping mesoscutellum posteriorly sensu Azevedo et al. (2018); metapectal-propodeal complex smooth laterally, lateral marginal carina distinct, dorsal surface of metapectal-propodeal complex hardly distinguishable, apparently smooth, posterior corner with small lateral dentiform projection. Fore wing hyaline, reaching fourth metasomal segment (LFW: 2.48 mm); C, Sc+R, M+Cu, 1A tubular; 1Rs&1M angled at junction with Rs+M; Rs+M poorly pigmented, spectral; cu-a post-furcal to 1M; 2Cu pigmented, then fading; pterostigma rounded; short stub of R1 tubular distal to pterostigma: 2r-rs&Rs arising on distal half of pterostigma, long but not closing [2R1] cell. Proleg with protrochanter originating from apex of procoxa; profemur moderately thickened; tibial spur formula 1-2-2, pro- and metaspurs long, mesospurs shorter; two tarsal claws, only slightly curved; proarolium well-developed; metafemur moderately thickened; first metatarsomere as long as 2-4 combined. - Metasoma longer than mesosoma (length 2.69 mm); fusiform, tapering at apex; petiole conspicuous and narrow: six exposed tergites; T2 longest, laterally covering sternites; T1, T3, T4 and T5 subequal in length; short and narrow sting exserted.
