Type material: Holotype, female, INDIA: Uttar Pradesh, Etawah, 26°47′N, 79°02′E, 14, 15. vii. 2008, Coll. M. Sharif (ZDAMU). Deposited in Insect Collection, Department of Zoology, AMU, Aligarh (ZDAMU).
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).
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).
