Morphology.

Head: Head finely and densely punctate. Occiput flat and polished. Temple broad and convex, finely punctate. Mandible very short, upper tooth longer than lower tooth (Fig. 1D). Ocelli slightly large; diameter of median ocellus 1.1 times as long as distance between ocellus and eye; lateral ocellus separated from eye by 0.9 times lateral ocellus diameter.

Mesosoma: Pronotum covered with transverse striae (Fig. 1E); epomia distinct. Mesoscutum finely and densely punctate; notaulus absent (Fig. 1G). Mesopleuron roughly punctate, reticulate; postpectal carina complete; epicnemial carina short; sternaulus absent; speculum convex, impunctate, polished (Fig. 1F); scutellum finely granulate. Propodeum with numerous transverse rugae and reticulate; basal area and areola separated by anterior transverse carina (Fig. 1H); areola and petiolar area not separated, impressed medially; costula complete (Fig. 5A); spiracle very small, round, connected to pleural carina; distance between spiracle and pleural carina 1.7 times as diameter of spiracle (Fig. 1I). Hind tibia with short spines; ratios between hind tarsal segments 4.5: 2.2: 1.6: 0.8: 0.9. Fore wing with areolet; basal vein opposite nervulus (Fig. 1L); nervellus not intercepted; discoidella absent.

Metasoma: Thyridium small, oval; separated from base of 2nd tergite by more than 3.0 times its diameter; distance between base of 2nd tergite and thyridium 0.6 times distance between base of 2nd tergite and spiracle (Fig. 1K). 6th and 7th tergites deeply emarginate apically (Fig. 1M). Ovipositor (Fig. 1N) shorter than metasoma, 1.4 times as long as hind tibia.

Male. Unknown.
