Diagnosis.

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

Description.

Male. Body mostly dark brown; palpi and anterior 0.6-0.7 of T1 white-yellow; mandibles, scape, pedicel and most of legs (except for posterior 0.2-0.3 of metatibia and metatarsus which are brown) yellow; anterior laterotergites and sternites white; flagellomeres brown; wings hyaline, most veins brown. Head with relatively large tentorial pits and palpi. Traces of an occipital carina latero-dorsally. Flagellomeres with two rows of placodes. Scutoscutellar sulcus relatively wide and deep, with 4-6 strongly defined crenulae. Scutellar disc with coarse and slightly raised posteromedian band of rugosity. Propodeum with complete areola and incomplete transversal carina. Fore wing with large and quadrate areolet. Metacoxa relatively long, extending to the posterior margin of T3. T1 shape relatively unique (better illustrated in Figs 36E, F , 37D-F ), with much wider anterior 0.6-0.7 and strongly narrowed posterior 0.3, so that widest part of tergite (near anterior margin) is around 4.0 × narrowest width (on posterior margin). T1 anterior 0.6-0.7 desclerotized and slightly concave. T2 very long and thin, although slightly widening towards posterior margin. Area surrounding spiracles on laterotergite 2 partially sclerotized and same color than T2, giving the impression of T2 having "three peaks" (the largest and central one being the actual T2, the two smallest and lateral ones being the area surrounding spiracles on laterotergites; better illustrated in Figs 36E, F , 37D, F ). T3+ smooth and with sparse, relatively long setae. Body measurements (mm). F2 L: 0.26; F3 L: 0.28; F14 L: 0.23; F15 L: 0.23; Malar sulcus L: 0.08; Mandible W: 0.09; T1 L: 0.36; T1 W at posterior margin: 0.08; T1 maximum W: 0.30; T2 W at anterior margin: 0.08; T2 W at posterior margin: 0.49; T2 L: 0.25; Metafemur L: 0.83; Metafemur W: 0.23; Metatibia L: 1.07; Inner spur L: 0.20; Outer spur L: 0.18; First segment of Metatarsus L: 0.42; Body L: 2.97; Fore wing L: 2.90. T1 L is approximate.

Female. Unknown.

Biology.

Host unknown.

Distribution.

Thailand, Vietnam.

Molecular data.

The holotype and one paratype (CNC521392) rendered almost complete barcodes (601 and 614 bp respectively), whereas for the other paratype a partial sequence (497 bp) was also available. Those sequences represent in BOLD two closely related BINS (BOLD:ADE3103 and BOLD:ADE4131), which are 3% different. As explained in the genus description, for the time being we prefer to consider all those specimens as belonging to the same species, although barcodes suggest they could actually represent two different species.

Etymology.

The species refer to the species distribution in the Oriental region.
