Paratypes, 6 females, same as holotypes. INDIA: Uttar Pradesh, Aurrayya, 26°28′N, 79°31′E, 16. xi. 2009, Coll. M. Shamim (ZDAMU). Deposited in Insect Collection, Department of Zoology, AMU, Aligarh (ZDAMU).
Etymology: The species is named with its type locality.
Discussion: The new species Streblocera (Eutanycerus) aurrayyus sp. nov. is closely related to Streblocera (Eutanycerus) shawi sp. nov., but it differs by having (1) antennal segments 21 (antennal segments 20 in shawi); (2) scape 8.8× its width (scape 6× its width in shawi); (3) intertentorial line 1.3× tentorio-ocular line (intertentorial line as long as tentorio-ocular line in shawi); (4) first metasomal tergite 1.8× its apical width, its surface apical one-third smooth, remaining longitudinally striate (first metasomal tergite 2.1× its apical width, its surface basally smooth, remaining longitudinally striate in shawi); (5) forewing vein m – cu interstitial (forewing vein m – cu slightly antefurcal in shawi).
The new species Streblocera (Eutanycerus) aurrayyus sp. nov. is also related to Streblocera (Eutanycerus) cornis Chen and Achterberg, 1997. However, it differs by having (1) antennal segments 21 (antennal segments 25 in cornis); (2) length of scape 8.8× its width (length of scape 7.1× its width in cornis); (3) first flagellomere with 1 sensillum (first flagellomere with 7 sensilla in cornis); (4) occipital carina incomplete, dorsally shortly interrupted (occipital carina complete in cornis).
