Type material: Holotype, female, INDIA: Madhya Pradesh, Bhind, 26°36′N, 78°46′E, 15. vi. 2007, Coll. M. Sharif & M. Shamim (ZDAMU). Deposited in Insect Collection, Department of Zoology, AMU, Aligarh (ZDAMU).
Paratypes, 4 females, same as holotypes. INDIA: Madhya Pradesh, Gwalior, 26°14′N, 78°10′E, 22. v. 2010. Coll. M. Shamim (ZDAMU). Deposited in Insect Collection, Department of Zoology, AMU, Aligarh (ZDAMU).
Etymology: The species is named for its smooth mesopleuron.
Discussion: The new species Streblocera (Eutanycerus) levipleuron sp. nov. resembles Streblocera (Eutanycerus) aurrayyus sp. nov. However, it differs by having (1) middle lobe of mesoscutum smooth, setose (middle lobe of mesoscutum sparsely punctate in aurrayyus); (2) mesopleuron largely smooth (mesopleuron anterodorsally finely crenulate, setose, remaining largely smooth in aurrayyus); (3) hind tibial spurs 0.17× hind basitarsus (hind tibial spurs 0.20× hind basitarsus in aurrayyus); (4) hind coxa smooth (hind coxa sparsely punctate in aurrayyus).
The new species Streblocera (Eutanycerus) levipleuron sp. nov. also resembles Streblocera (Eutanycerus) obtusa Chen and Achterberg, 1997. However, it differs by having (1) antennal segments 21 (antennal segments 22 in obtusa); (2) length of scape 8.8× its width (length of scape 5× its width in obtusa); (3) propodeum apically smooth, remaining reticulate, rugose (propodeum areolate with rugae between carinae in obtusa); (4) surface of first metasomal tergite basally more than half smooth, remaining longitudinally striate (surface of first metasomal tergite weakly longitudinally rugose in obtusa).
