Mesosoma: ( Fig. 4 ) Midlobe of mesoscutum about as long as wide (87: 84), Midlobe of scutellum 1.5X as long as wide, dorsellum as long as propodeum. Fore wings ( Fig. 3 ), hyaline, about 2.5X as long as broad (464: 188), disc densely setose up to venation, covering half of the wing length, marginal fringe long about one-fourth of the wing width.

Comments: Tumidiclava breviclavata sp. nov. is very close to Tumidiclava tenkasiensis Yousuf & Shafee but can be separated by having antennae with scape more than 3X as long as wide; pedicel more than 1.5X as long as wide; club less than 2X as long as wide. Fore wings, 2.5X as long as broad. [In Tumidiclava tenkasiensis , antennae with scape slightly less than 3X as long as wide; pedicel 1.5X as long as wide; club more than 2X as long as wide.
