Paratypes, 3 females, same as holotypes. INDIA: Uttar Pradesh, Kannauj, 27°03′N, 79°56′E, 22. v. 2010. Coll. M. Shamim ( ZDAMU). Deposited in Insect Collection, Department of Zoology , AMU, Aligarh ( ZDAMU) GoogleMaps .
Etymology: The new species is named after the entomologist Dr Scott Richards Shaw, in recognition of his great contribution to the taxonomy of parasitic Hymenoptera .
Discussion: The new species Streblocera (Eutanycerus) shawi sp. nov. is related to Streblocera (Eutanycerus) shujauddini sp. nov. However, it differs by having (1) antennal segments 20 (antennal segments 21 in shujauddini ); (2) scape 6× its width (scape 7.6× its width in shujauddini ); (3) intertentorial line as long as tentorio-ocular line (intertentorial line 1.2× tentorio-ocular line in shujauddini ); (4) clypeus 2.3× its height, finely punctate, sparsely setose (clypeus 2.9× its height, smooth, setose in shujauddini ); (5) side of scutellum reticulate, setose (side of scutellum alutaceous, setose in shujauddini ); (6) distance across spiracles 0.57× distance from spiracles to apex of first metasomal tergite (distance across spiracles 0.93× distance from spiracles to apex of first metasomal tergite in shujauddini ).
The new species Streblocera (Eutanycerus) shawi sp. nov. is also related to Streblocera (E.) okadai Watanabe, 1942 . However, it differs by having (1) surface of first metasomal tergite basally smooth, remaining longitudinally striate (surface of first metasomal tergite longitudinally striate in okadai ); (2) propodeum apically smooth, remaining uniformly reticulate, rugose (propodeum apically smooth, remaining uniformly reticulate, rugose, with irregular transverse carinae in okadai ).
