Genus Phradis Foerster, 1869  

Type species.

Thersilochus (Phradis) brevis   Brischke, 1880.

A moderately large predominantly Holarctic genus with 20 species in the Nearctic region (including two species from Mexico), ca. 40 species in the Palaearctic region, and several species known from Peru, South Africa, and Australia. In Europe, species of Phradis   have been reared from sap beetle larvae ( Coleoptera  : Nitidulidae   : Meligethes   spp.) feeding on rape, but no host record is known for any Nearctic species ( Horstmann 2013a).

Two species of Phradis   were known from Mexico until now ( Khalaim and Ruíz-Cancino 2018), and the third species, P. belovi   sp. nov., is described from North Mexico in this paper. The genus is extremely rare in Mexico as all known Mexican species are represented by a single holotype. Horstmann (2013a) in his revision of the Nearctic fauna, also noted that many Nearctic species are rarely collected, and six of 18 revised species (33%) are known from only one specimen. A key to three Mexican species of Phradis   is provided below.
