Genus Pteroherpus Gaud, 1981

A detailed generic revision of the family Pteronyssidae (considered as the subfamily of Avenzoariidae) was carried out by Faccini and Atyeo (1981). The authors of that revision noted that the genus Pteroherpus included 12 described species and they also recognized three species-groups within the genus: benoiti, holoplax and monacrotrichus. Other species were later described (Mironov 1992, Mironov & Kopij 2000, Mironov & Wauthy 2006), and a recent revision of Pteroherpus (Mironov & Wauthy 2008) added three more new species, raising the number to 18, and arranged them in four species-groups: hoplophorus (10 species), diploplax (6 species), josephi (1 species) and nicator (1 species). After this revision two other species of the genus were described: Pteroherpus garrulacis Mironov and Proctor, 2011 belonging to the species-group diploplax and Pteroherpus surmachi Mironov, 2011 which cannot be classified in any of mentioned species groups having a distinct combination of characters both in the female and in the male.
