T 1 1.90 × longer than apical width.
Etymology
Etymology. This species name refers to the posterior of mesoscutum, which is nearly devoid of setae.
Distribution
Distribution.China (Hubei).
Discussion
Remarks. Differences between the male and female are minor. In female specimens 2 CUb arises from the middle of the 1 st subdiscal cell; in the male it arises below the middle of 1 st subdiscal cell. In the male specimen, the 2 nd submarginal cell is more slender than in the female specimen. Tanycarpa stribog and T. gymnonotum are closest to each other morphologically in that the mesoscutum at most has sparse pubescence. The biggest differences are in T. stribog the mesoscutum has pubescence anteriorly and along the notauli lines, the propodeum has a clear longitudinal medial ridge, and T 1 is short; in T. gymnonotum the mesoscutum is smooth and setiferous (Fig. 11), the propodeum lacks a clear longitudinal ridge, and T 1 is longer.
