A new species of Prionychus Solier, 1835 from Morocco and redescription of Prionychus anthracinus (Mulsant, 1856) and Prionychus lugens (Küster, 1850) (Coleoptera, Tenebrionidae, Alleculinae)

In this work we describe a new species of Prionychus from northern Morocco, specifically in the region of Nador, near Melilla. Prionychus alfonsoblancoi sp. nov. belongs to those species in which the prosternum, ahead of procoxa, angles downards in a flat or slightly convex slope, the elytra have almost no striae, the anterior margin of pronotum has no border and they show a chestnut colouration. Within the Iberian/Maghreb area, these characters make P. alfonsoblancoi resemble only P. lugens, a species from which it can be clearly separated by the length of the antennae, the pronotal punctuation and the structure of the aedeagus. P. alfonsoblancoi is the fourth species present in Morocco and, by extension, in North Africa. Given the biometrics indices currently used to describe the species of this subfamily, it has been decided to re-describe Prionychus anthracinus and Prionychus lugens according to up-to-date standards. A dichotomous key to the species of the genus that inhabit the Iberian peninsula and northern África has also been developed.
