Material examined.

Holotype, female, T. barrowi : INDIA: Himachal Pradesh St., Dalhousie , 11.VIII.1906, reared, H. J. W. Barrow, B.M. TYPE HYM. 9.323 (deposited in BMNH).

Comments.

The holotype specimen consists of a metasoma and a wing, which are insufficient to separate this species from other species of Trissolcus , nor can it be confidently distinguished with the descriptions by Dodd (1920) and Nixon (1938). The condition of the type is so poor that designation of a neotype is warranted. However, this is confounded by the host association on the holotype labels that indicate that it emerged from the egg of a hawk moth ( Sphingidae )- which is most likely an error. In the absence of material from vicinity of the type locality required for designation of a neotype, we presently treat T. barrowi as nomen dubium.
