This species is very close to Brachymeria euploeae  (Westwood) in colour, but differs from Brachymeria euploeae  in having the metasoma not globose or subglobose (as in Brachymeria euploeae  ) and the ovipositor sheath is visible in dorsal view (in Brachymeria euploeae  ovipositor sheath not visible in dorsal view).

Hind tibia yellow with a narrow band at extreme base and the ventral carina, black. Pubescence on body grayish white and dense on front of head.

Head. Head with pre-orbital carina absent or hardly distinct; post-orbital carina present and reaching geno-temporal margin; antennal clava slightly shorter or at the most as equal to twice length of preceding segment;

Mesosoma. Pits on mesosoma close and interstices carinate and rugose; apex of scutellum rounded or slightly entire. Dorsal margin of pronotal panel slightly arched.

Wings. Fore wing with PMV 0.33-0.36 × length of MV; SMV slightly shorter than twice MV.

Legs. Hind coxa without ventro-mesal tooth; hind femur without an inner basal tooth, outer ventral margin with a row of irregular teeth.

Metasoma. Metasoma sessile but very short petiole visible; subacute and ovate; T1 smooth and shiny; its posterior margin straight; following tergites weakly shagreened.
