( Figs. 1–12 View FIGURES 1 – 6 View FIGURES 7 – 12 )

Diagnosis. This new species can be distinguished from all other Chinese Bathanthidium s. str. by the following combination of characters: fovea behind propodeal spiracle rounded, delimited by a strong carina; mandible with 4 teeth; third flagellum as long as second one; clypeus black, without lateral yellow marks; paraocular area at ventral extreme with a little triangle dull yellow mark; scutellum without yellow mark apically; T1 without lateral yellow marks, T2 with pair of small, median, stripe-like yellow marks, T3-T5 with broader entire yellow bands.

Description. Female. BL=9.0mm ( Fig.1 View FIGURES 1 – 6 ); head broader than long, HW: HL=60: 50 ( Fig.2 View FIGURES 1 – 6 ); gena broader than eye, GW: EW=15: 12 ( Fig.3 View FIGURES 1 – 6 ); width of metasoma slightly narrower than the width between the tegulae. Clypeus broader than long, with punctures on clypeus, vertex and genae larger and denser; frons with dense punctures, size of punctures smaller than that on vertex; mesoscutum and scutellum with round, dense punctures ( Fig.4 View FIGURES 1 – 6 ); mandible widened apically, with 4 teeth ( Fig.5 View FIGURES 1 – 6 ); third flagellum as long as second one; subantennal suture directed toward outer margin of antennal socket; face without longitudinal median ridge ( Fig.2 View FIGURES 1 – 6 ); fore wing with two submarginal cells of roughly equal in length, basal vein nearly straight, meeting vein Cu at acute angle, 2nd m-cu slightly exceeding apical margin of 2nd submarginal cell, marginal cell distal to stigma on costa longer than stigma; stigma nearly twice as long as broad, prestigma short, less than twice as long as broad ( Fig.6 View FIGURES 1 – 6 ); jugal lobe of hind wing less than half as long as vannal lobe, vein cu-v less than half as long as second abscissa of M+Cu; pronotal lobe with a dorsal-anterior carina; omaular carina absent; axilla rounded and not produced posteriorly ( Fig.4 View FIGURES 1 – 6 ); metanotum without median spine; scuto-scutellar fovea open, each half of scuto-scutellar fovea about four times as wide as long ( Fig.4 View FIGURES 1 – 6 ); fovea behind propodeal spiracle rounded, delimited by strong carina ( Fig.7 View FIGURES 7 – 12 ), basal zone of propodeum distinct laterally, with regular, shiny, nearly horizontal pits ( Fig.8 View FIGURES 7 – 12 ); basal margin of T1 with carina; pygidial plate absent; S6 unmodified, margin thin; front and middle tibia with one spine on outer side ( Fig.9 View FIGURES 7 – 12 ), hind tibia without spine; outer surface of tibiae without tubercles; tarsal claws with inner median tooth, arolia present and large ( Fig.10 View FIGURES 7 – 12 ); ventral surface of metasoma with scopa of pollen-carrying hairs ( Fig.11 View FIGURES 7 – 12 ). Clypeus, mandible, vertex, frons, pronotal lobe, mesoscutum, scutellum, and all legs black; paraocular area at ventral extreme with a little triangle dull yellow mark ( Fig.2 View FIGURES 1 – 6 ); metasoma black, except T2 with median pair of small stripe-like yellow marks, T3- T5 with broader entire yellow bands ( Fig.12 View FIGURES 7 – 12 ). Pubescence sparse; face, mesosoma and anterior surface of T1 covered with short, sparse white hairs; all legs covered with sparse blackish-brown short hairs; apex of T6 with denser dull brownish-yellow hairs; S2-S5 with denser, longer golden-yellow hairs forming scopa ( Fig.11 View FIGURES 7 – 12 ).
