Paratypes, 3 females, same as holotypes. INDIA: Uttar Pradesh, Etawah, 26°47′N, 79°02′E, 14, 22. v. 2007. Coll. M. Sharif & M. Shamim (ZDAMU). Deposited in Insect Collection, Department of Zoology, AMU, Aligarh (ZDAMU).

Etymology: The new species is named after the Indian entomologist Professor Shujauddin, in recognition of his great contribution to the taxonomy of parasitic Hymenoptera.

Discussion: The new species Streblocera (Eutanycerus) shujauddini sp. nov. is related to Streblocera (Eutanycerus) aurrayyus sp. nov. However, it differs by having (1) face 1.8× as wide as long, uniformly granulate, densely setose (face 1.2× as wide as long, punctate in aurrayyus); (2) first metasomal tergite 2.2× its apical width, its surface longitudinally striate (first metasomal tergite 1.8× its apical width, its surface apically one-third smooth, remaining longitudinally striate in aurrayyus); (3) distance across spiracles 0.93× distance from spiracles to apex of first metasomal tergite (distance across spiracles 0.57× distance from spiracles to apex of first metasomal tergite in aurrayyus); (4) ovipositor sheaths 0.17× hind basitarsus (ovipositor sheath 0.84× hind basitarsus in aurrayyus; (5) scape 7.6× its width (scape 8.8× its width in aurrayyus).

The new species Streblocera (Eutanycerus) shujauddini sp. nov. is also related to Streblocera (Eutanycerus) linearata Chen and Achterberg, 1997. However, it differs by having (1) flagellum geniculated at seventh flagellar segments (flagellum not geniculated in linearata); (2) antennal segments 21 (antennal segments 23 in linearata); (3) first flagellomere with 1 sensillum (first flagellar segment with 3 sensilla in linearata); (4) face medially depressed, uniformly granulate, densely setose (face densely punctate and setose in linearata).
