Paratypes, 5 females, same as holotypes. INDIA: Uttar Pradesh, Etawah, 26°47′N, 79°02′E, 14, 22. v. 2010, Coll. M. Sharif (ZDAMU). Deposited in Insect Collection, Department of Zoology, AMU, Aligarh (ZDAMU).
Etymology: The species name refers to its type locality.
Discussion: The new species Streblocera (Eutanycerus) etawahiana sp. nov. resembles Streblocera (Eutanycerus) achterbergi sp. nov. However, it differs by having (1) clypeus sparsely granulate (clypeus smooth in etawahiana); (2) frons medially smooth, remaining striate, near eye margin punctate with hairs (frons smooth, near eye margin sparsely setose in etawahiana); (3) scape 8× its width (scape 9.4× its width in etawahiana); (4) intertentorial line 0.75× tentorio-ocular line (intertentorial line 1.5× tentorio-ocular line in etawahiana); (5) antennal segments 21 (antennal segments 20 in etawahiana); (6) length of mesosoma 2.1× its width (length of mesosoma 1.8× its width in etawahiana).
The new species Streblocera (Eutanycerus) etawahiana sp. nov. also resembles Streblocera (Eutanycerus) galinae Belokobylskij, 1987. However, it differs in having (1) intertentorial line 0.75× tentorio-ocular line (intertentorial line almost 2× tentorio-ocular line in galinae); (2) first flagellomere 2.5× its width and as long as pedicel (first flagellomere nearly 3.4× its width and 1.5× as long as pedicel in galinae); (3) length of vein r 0.22× width of pterostigma (length of vein r 0.42–0.5× width of pterostigma in galinae).
