Diagnosis. Interantennal space with a flat triangular elevation that narrows to a short ridge posteriorly and then divides into two short carinae that approach the median ocellus (Fig. 1C 1); third labial palpomere small, less than 1/3 length of apical palpomere; scutellar groove with 5 longitudinal ridges (Fig. 1G); fore tibia with 2−8 thickened spines apically (Fig. 1J); mid tibia with 9−10 pegs along apical tibia (Fig. 1K); hind tibia with 12−13 pegs around apical tibia (Fig. 1L); T1 produced laterally around spiracles and apical 1/3 slightly produced (Fig. 1I); T2 widened apically (Fig. 1I).

Description. ♀, body length 4.5 mm; ovipositor length/body length ratio = 0.72; length of fore wing 3.5 mm.

Head. Antenna with 29 flagellomeres (Fig. 1A); antennal sockets not margined with carinae (Fig. 1C); interantennal space with a flat triangular elevation that narrows to a short ridge posteriorly and then divides into two short carinae that approach the median ocellus (Fig. 1C 1); ocelli forming an equilateral triangle (Fig. 1C); eyes glabrous, length of eyes 3.5 × longer than temple in dorsal view (Fig. 1C); mouthparts short (normal), gena not elongate (Fig. 1D); third labial palpomere small, less than 1/3 length of apical palpomere; face 1.6 × wider than high in anterior view (Fig. 1E); OD: POL: OOL = 10: 7: 18.

Mesosoma. Length of mesosoma 1.5 × its height in lateral view (Fig. 1F); mesopleuron largely smooth (Fig. 1F); precoxal sulcus absent anteriorly and remainder shiny and smooth (Fig. 1F); notauli absent (Fig. 1G); scutellum triangular, smooth (Fig. 1G) and slightly convex (Fig. 1F); scutellar groove with 5 longitudinal ridges (Fig. 1G); basal 3/4 of propodeum with irregular and trapezoid-shaped carinae, apical 1/4 propodeum with 3 longitudinal ridges, slightly smooth and moderately setose laterally (Fig. 1H); metapleuron setose (Fig. 1F).

Fore wing (Fig. 1B). Fore wing slightly infuscate in apical half; vein SR1 present, marginal cell narrow and long, vein m-cu divergent posteriorly relative to vein 1-M, vein CU1b absent; vein 1-SR+M mostly absent; second submarginal cell small; cell about the same diameter as wing veins.

Metasoma. T1 smooth, lacking microsculpture and carina, apical 1/3 of T1 produced around spiracles laterally (Fig. 1I); T2 wider than long and smooth, widened apically (Fig. 1I); maximum length of length of T1 = T2 (Fig. 1I); ovipositor longer than 1/2 length of metasoma (Fig. 1A).

Legs. Fore- and midtarsal claws with a basal lobe; hind trochantellus lacking longitudinal carinae; fore tibia with 2 thickened spines apically (Fig. 1J); mid tibia with 10 pegs (Fig. 1K); hind tibia with 13 pegs apically (Fig. 1L).

Colour. Body mainly orange and black, antennal scape and pedicel black, flagellomeres brown (Fig. 1A); head mostly orange, anterior 2/3 ocellar triangle black (Fig. 1C); teeth apically dark brown (Fig. 1D); prothorax orange, mesothorax 1/2 latero-ventrally and ventrally dark brown (Fig. 1F); scutellum orange (Fig. 1F); metathorax black (Fig. 1F); veins mostly light brown and parastigma dark brown (Fig. 1B); metasomal terga predominantly dark with some white (Fig. 1I); fore tibia orange (Fig. 1J); mid tibia and hind tibia light yellow and black (Fig. 1K; Fig. 1L).

Male. Unknown.

Material examined. Holotype ♀ (H369), THAILAND, Prachuab Khiri Khan, Khao Sam Roi Yot NP, foot of Khao Taen, 12°8.75’N, 99°57.988’E, 1 m, Malaise trap, 17–24.V.2009, Yai Amnad leg. ♀ (BIIC, 2020HN00385), CHINA, Wanning City Xinglong South Medicine Park Visitor Center, Hainan, 19°30′57.19″N, 109°29′33.10″E, elevation 123.14 m, Malaise trap, 15−31.VII.2020, Chun Yang Xu.

Distribution. Khao Sam Roi Yot National Park, Thailand; Wanning City Xinglong South Medicine Park, Hainan, China.

Note: The Chinese specimen is very similar to the holotype and has minor differences in color (Thai specimen: mesothorax latero-ventrally and ventrally and teeth apically orange, Chinese specimen: mesothorax latero-ventrally and ventrally and teeth apically dark brown), scutellar groove (Thai specimen: with 6 longitudinal ridges, Chinese specimen: with 5 longitudinal ridges), and legs (Thai specimen: fore tibia with 7−8 thickened spines, mid tibia with 9 pegs, hind tibia with 12 pegs, Chinese specimen: fore tibia with 2 thickened spines, mid tibia with 10 pegs, hind tibia with 13 pegs, part of the legs lost after observation).
