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) GoogleMaps .

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 ).
