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 ).
