Discussion: The new species Streblocera (Eutanycerus) kanpurensis sp. nov. is related to Streblocera (Eutanycerus) achterbergi sp. nov. However, it differs by having (1) scape 8× as long as wide (scape 9.4× as long as wide in achterbergi ); (2) clypeus punctate, densely setose (clypeus smooth, setose in achterbergi ); (3) first metasomal tergite basally one-third smooth, remaining longitudinally striate (first metasomal tergite apically and basally smooth, remaining longitudinally striate in achterbergi ); (4) distance across spiracles 0.48× distance from spiracles to first metasomal tergite (distance across spiracles 0.62× distance from spiracles to first metasomal tergite in achterbergi ); (5) hind coxa smooth (hind coxa sparsely punctate in achterbergi ); (6) hindwing 4.5× as long as wide (hindwing 3.1× as long as wide in achterbergi ).

The new species Streblocera (Eutanycerus) kanpurensis sp. nov. is also related to Streblocera (Eutanycerus) affinis Belokobylskij, 1987 . However, it differs by having (1) face punctate, densely setose (face densely punctate, rugose in middle in affinis ); (2) antennal segments 20 (antennal segments 24 in affinis ); (3) surface of first metasomal tergite basally one-third smooth, remaining longitudinally striate (surface of first metasomal tergite wholly rugose in affinis ).
