Male genitalia (genitalia of 6 specimens studied). Median lobe of aedeagus in lateral view thinner basally, with equal width at middle and at apex, apex ventrally slightly S-curved in front ( Fig. 3 ); same ventrally straight and slender ( Fig. 13 ); same in dorsal view with apex visible from above ( Fig. 17 ). Copulatory piece convex laterally, ventrally with medial lobe protruding in front ( Figs. 3 , 13 ).

Notes. The study of the genitalia of the lectotype (Silla Mt., type locality) and a single paralectotype (from Vallo Lucano) of Platyderus canaliculatus jannonei Binaghi, 1955 confirmed the synonymy of this taxon and P. neapolitanus (see also Degiovanni 2005). Only, a single paralectotype of the former taxon was found to belong to P. paganettii sp. n. (see below).
