Brachymeria shansiensis  Habu, 1961: 80-82 (♀, holotype, China ( EIHU); Joseph, Narendran & Joy, 1970: 22-23. (keyed and redescribed); Narendran 1989: 239, 267 (keyed).


1 ♀ ( RMNH), "Vietnam: Ninh Thuân, Núi Chúa N. P., dry south part; Mal[aise] traps, 100-188 m, 22-29.v.2007, C. v. Achterberg & R. de Vries, RMNH’07”.


This species is very similar to Brachymeria excarinata  Gahan by having similar colour and no post-orbital carina. However, it differs from Brachymeria excarinata  in having T1 shagreened (sculpture absent in Brachymeria excarinata  ), eyes with sparse pubescence (without pubescence) and the subbasal yellow colour of hind tibia much further developed than that of Brachymeria excarinata  .


(female from Núi Chúa N. P.). ♀, length of body 4.2 mm.

Colour. Black with following parts as follows: eyes pale grayish yellow with reflecting yellow spots; ocelli reflecting pale yellow; tegula yellowish white; all coxae concolorous with mesosoma; trochanters reddish brown; femora black with apex yellow; fore and mid tibiae pale yellowish white; hind tibia yellowish white with brownish or dark brown median band (Fig. 68); all tarsi white; telotarsi brown, its apical pulvilli with whitish pads; wings hyaline with veins brown.

Head. Width of head in anterior view 1.4 × as broad as its length; width in dorsal view 2.9 × as broad as long, as broad as mesoscutum (excluding tegulae); face and vertex with close setigerous pits, interstices micro-sculptured, narrower than half diameter of a pit. POL 4 × OOL; AOL longer than OOL (7:5); interocular width 2.1 × POL; scrobe smooth and shiny, reaching anterior ocellus; height of malar space 0.4 × height of eye in profile; eyes sparsely pubescent; height of eye 1.6 × eye length in profile; anterior genal angle subhorizontal; posterior genal angle obtuse subhorizontal; pre-orbital carina present; post-orbital carina absent; area below interantenal projection narrowly smooth. Antenna with radicula 0.2 × length of scape; scape not quite reaching anterior ocellus. Relative L:W of antennal segments:scape = 16:5; pedicel = 4:4; ring segment = 1:4; F1 = 5:6; F2 = 5:7; F3 = 5:7; F4 = 5:7; F5 = 5:7; F6 = 5:8; F7 = 4:7; clava = 9:6.

Mesosoma. Pronotum with anterior marginal carina separating collar absent medially, posterior margin a little concave, surface with close umbilicate setigerous pits, interstices sculptured, somewhat carinate; mesoscutum with close pits as in pronotum, apex entirely or largely rounded. Propodeum with median longitudinal foveola and sublateral foveolae present; postspiracular tooth hardly district.

Wings. Fore wing 2.7 × as long as wide; speculum slightly open behind; relative length of CC = 24; SMV = 11; parastigma = 2; MV = 10; PMV = 5; STV = 2.

Legs. Hind coxa densely punctate and pubescent on ventral side without an inner ventro-mesal tooth; hind femur 1.9 × as long as wide, outer disc mat like with dense minute pubescence, outer ventral margin with a raw of 14 differently sized teeth, without an inner basal tooth; second hind tarsal segment distinctly longer than wide in dorsal view (Fig. 70).

Metasoma. Metasoma slightly longer than mesosoma (22:21); T1 faintly shagreened; T2 with a patch of pubescence on each side dorsally; T3 to T5 with cross rows of setae dorsally and sides. T6 with 6-7 cross rows of setigerous pits, interstices reticulate. Ovipositor sheath visible in dorsal view, a little shorter than epipygium in dorsal view.

Male. Similar to female, but metasoma slightly shorter than or nearly as long as mesosoma.


China, India, Vietnam (new record).


In some specimens entire base of hind tibia reddish brown while in a few others reddish brown only latero-basally.
