Diagnosis

Vein 2-SR of fore wing bent ( Fig. 32G ); second submarginal cell of fore wing robust ( Fig. 32G ); mesopleuron largely granulate and rather dull; hypopygium with short robust triangular protuberance ( Fig. 32J ); clypeus with two minute teeth ( Fig. 32E ); apical half of hind tibia with dark brown patch ( Fig. 32K ); vein r of fore wing 0.5 × as long as vein 3-SR; head and mesosoma yellowish brown or dark brown; ocelli small; vein 2-SR of fore wing distinctly bent (holotype) to straight.

Etymology

Named after the mostly dark body of the holotype, from the Latin ‘ tenebricus ’ for ‘dark’.
