Brachymeria carinata Joseph, Narendran & Joy, 1970: 22 (♀, India (Calicut) (BMNH)).
Brachymeria shansiensis vietnamensis Joseph, Narendran & Joy, 1972: 348 ((♂ “♀”) Vietnam ( BPBM) (synonymised by Narendran 1989, with Brachymeria carinata Joseph, Narendran & Joy).
1 ♀ ( RMNH), "Vietnam: Ninh Thuân, Núi Chúa N. P., dry south part; Mal. traps, 100-180 m, 22-29.v.2007, C. v. Achterberg & R. de Vries, RMNH’07”; 1 ♀ ( BPBM), "Vietnam, 8.xi.1960, C.M. Yoshimoto"; 2 ♀, "Vietnam, 12-28.xii.1963, Gayden".
This species comes near Brachymeria margaroniae Joseph, Narendran & Joy in general appearance, but differs from that species in having: 1) hind tibia with base yellow (in Brachymeria margaroniae hind tibia with base reddish black); 2) area below scrobe with median raised smooth portion absent (in Brachymeria margaroniae area below scrobe with a raised median smooth portion) and 3) MV about 3 × PMV (in Brachymeria margaroniae MV twice PMV).
(based on specimen from Núi Chúa N.P.), ♀, length of body 4.3 mm.
Colour. Black with following parts as follows: eyes dull grayish yellow with pale reflecting yellow spots; ocelli pale reflecting yellow; tegula pale yellow; all coxae and trochanters concolorous with mesosoma; femora black with apices yellow; all tibiae and tarsi yellow with a black line along ventral margin of hind tibia; wings hyaline with veins brown. Pubescence silvery white.
Head. Width of head in anterior view 1.2 × its height; width in dorsal view slightly broader than mesosoma (excluding tegulae) (26:25), 2.4 × its length. POL 4 × OOL; AOL 2.3 × OOL; interocular distance 2.2 × POL; pre-orbital carina present but not reaching malar ridge; post-orbital carina absent; scrobe reaching anterior ocellus; area below scrobe without a raised smooth area, parascrobal space and face longitudinally striate reticulate and densely pubescent; area above parascrobal space and vertex with close umbilicate setigerous pits, interstices rugose and carinate; height of malar space 0.2 × height of eye in profile; eye height 2.4 × its length in profile; anterior genal angle slightly acute, 80° to the vertical axis of malar space; posterior genal angle obtuse to the subvertical geno-temporal margin; gena densely pubescent. Antennal radicula 0.2 × length of scape; scape not reaching anterior ocellus. Relative L:W of antennal segments:scape = 14:3; pedicel = 3:4; anellus = 1:3; F1 = 3:5; F2 = 4:5; F3 = 4:5; F4 = 3:6; F5 = 3:6; F6 = 3:6; F7 = 3:6; clava = 6:6.
Mesosoma. Pronotum, mesoscutum and scutellum with close posterior margin of pronotum, slightly concave; lateral panel of pronotum micro-reticulate, without cross striae or carinae and with transverse fovea at lower margin; pronotum with a cross carina adjacent to posterior margin; carina of anterior side limited to sides only; middle lobe of mesoscutum a little shorter than its width (15:17); scutellum a little wider than long (14:12), apex entire; propodeum 50° to the plain of scutellum (not vertical or subvertical); postspiracular tooth indistinct.
Wings. Fore wing 2.6 × longer than wide; relative length of veins SMV 13; parastigma = 5; MV = 17; PMV = 6; STV = 3.
Legs. Hind coxa smooth and shiny on dorsal half, densely pubescent and punctate on ventral side, inner ventro-mesal tooth absent; hind femur 1.8 × as long as wide, outer ventral margin with a row of 12 differently sized teeth; inner basal tooth absent; mesosternal shelf present.
Metasoma. Metasoma slightly longer than mesosoma in dorsal view (30:26); T1 reaching middle, densely micro-sculptured; T2 to T5 densely micro-sculptured and pitted, with pubescence on sides; T6 with 7-8 cross rows of shallow pits, pits and interstices rugose. Ovipositor sheath projecting posteriorly and visible in dorsal view.
