Diagnosis.

This is the only known species in the genus so far, thus the generic diagnosis works as the species diagnosis as well.

Description.

Female. Head and mesosoma dark brown to black; metasoma mostly brown, with anterior four laterotergites and sternites white or yellow; palpi, mandibles, scape, pedicel and most of legs (except for metatibia and metatarsus which are slightly darker) yellow; flagellomeres brown; wings hyaline, most veins white, pterostigma light brown-yellow. Body mostly smooth, with few, scattered, mostly shallow punctures. Flagellomeres with two rows of placodes. Pronotum with dorsal and ventral sulcus. Scutoscutellar sulcus relatively narrow but with numerous crenulae. Scutellar disc smooth, without posteromedian band of rugosity. Propodeum mostly smooth, with strongly defined median longitudinal carina and a few short carinae radiating from median one. Fore wing with quadrangular areolet. Hind wing with vannal lobe entirely setose. Metacoxa reaching to the posterior margin of T3. Last segment of tarsi relatively large, with small setae or spine (peg-like) on apical half, near the claws. Tarsal claws unique in Microgastrinae (better seen in Figs 39F-I ), with a very large basal tooth (longer than tarsal claw apex), and a median lobe (with setae arising from its margin, which seems slightly bilobate). T1 with central sulcus on anterior half, T2+ smooth. Ovipositor short but relatively thick and strongly curved downwards. Ovipositor sheaths with few, sparse, but relatively long setae. Body measurements (mm). F2 L: 0.19 (0.20); F3 L: 0.18 (0.18); F14 L: 0.11 (0.11); F15 L: 0.11 (0.10); Malar sulcus L: 0.06 (0.06); Mandible W: 0.08 (0.10); T1 L: 0.36 (0.33); T1 W at posterior margin: 0.09 (0.12); T1 maximum W: 0.14 (0.16); T2 W at anterior margin: 0.11 (0.13); T2 W at posterior margin: 0.38 (0.33); T2 L: 0.17 (0.17); Metafemur L: 0.65 (0.67); Metafemur W: 0.18 (0.18); Metatibia L: 0.83 (0.85); Inner spur L: 0.13 (0.15); Outer spur L: 0.12 (0.14); First segment of Metatarsus L: 0.29 (0.30); Ovipositor sheaths L: 0.26 (0.26); Body L: 2.06 (2.20); Fore wing L: 2.45 (2.55). Maximum W of T1 and T2 W at posterior margin are approximate for 2 specimens. T1 L, T1 W at posterior margin and T2 W at anterior margin are approximate for 1 specimen.

Male. Unknown.

Biology.

Host unknown.

Distribution.

Vietnam.

Molecular data.

Both the holotype and paratype rendered almost full barcode sequences (629 and 632 bp), representing BIN BOLD:ADE2636, which is 8.7% different from the closest Microgastrinae sequences currently available in BOLD.

Etymology.

Named after the country of the type locality.
