A new species of \u3ci\u3ePsalidognathus\u3c/i\u3e Gray, 1831 from Peru (Coleoptera: Cerambycidae: Prioninae)

Psalidognathus antonkozlovi (Coleoptera: Cerambycidae: Prioninae), a new species from Peru, is described and illustrated. The new species is included in a previous key. Currently, Psalidognathus Gray, 1831 encompasses 10 species distributed from Costa Rica to northern South America (Monné 2016). The species can be included in two groups: the “modestus” group, species without a spine at the apex of the basal antennomeres; and the “friendii” group, species with a spine at the apex of the basal antennomeres. Santos-Silva and Komiya (2012) published a provisional study of the species of the “modestus” group, considering seven species in it. The key to species of Psalidognathus by Quentin and Villiers (1983), although useful to separate both species groups, encompasses some problems as, for example, the length and color of the antennae, and pronotal pubescence. The study of a large series of specimens from Peru (mainly males) allowed describing a new species in the “modestus” group
