Pselaphogenius fiorii (Raffray, 1904)

Sabella, Giorgio, Viglianisi, Fabio Massimo & Bekchiev, Rostislav, 2019, A new species of Pselaphogenius Reitter, 1910 of the fiorii species group from southern Italy (Coleoptera, Staphylinidae, Pselaphinae), Zootaxa 4585 (2), pp. 387-394 : 388

Pselaphogenius fiorii species group:

The species of Pselaphogenius of the fiorii group have symmetric aedeagi (except P. lucanicus Besuchet, 1964 which shows an aedeagus partially asymmetric with the presence of a ventral lamina), characterized by two evident lateral apophyses of the basal capsule, two well developed and sinuated parameres, one median apical lamina, and the armature of internal sac simple consisting of a single piece. Although some of these portions are sometimes recognizable, despite being more or less modified, in the structure of the aedeagus of the other species of the genus Pselaphogenius , they never show the symmetry that characterizes the aedeagi of the species of the Pselaphogenius of fiorii species group.
