Polyphrix mexicanus Kasparyan & Ruíz 2008:157 –158, 366. Description, figure. Holotype Ƥ at UATM.

Comments. This species was originally described under Polyphrix . However, it shows many features that disagree with the generic definition, such as ventral tooth of mandible shorter than dorsal one (vs. longer), occipital carina meeting hypostomal carina (vs. not meeting), deep notaulus (vs. faint), epomia present (vs., absent), transverse wrinkles of propodeum very close (vs. widely spaced) and metasomal tergites 1 and 2 polished. All of these characters are, however, typical of Prosthoporus , as are the absence of hind wing vein 2- 1A, metasomal tergites 7 and 8 longer than 5-6, and the ventral valve of the ovipositor slightly overlapping the dorsal valve.

Prosthoporus and Polyphrix are, indeed, generally similar and probably related, as stressed in the present work. The description and figures of P. mexicanus , altogether with the generic definition of Polyphrix as revised herein, support accurately its placement in Prosthoporus .

With the new status, P. mexicanus represents the first record of Prosthoporus for North America, in an area often considered as part of the Nearctic region.
