A new species of Pselaphogenius Reitter, 1910 of the fiorii species group from southern Italy (Coleoptera, Staphylinidae, Pselaphinae) Author Sabella, Giorgio Author Viglianisi, Fabio Massimo Author Bekchiev, Rostislav text Zootaxa 2019 2019-04-12 4585 2 387 394 journal article 27330 10.11646/zootaxa.4585.2.12 f0388f56-ed5e-4d43-baf3-8bda92478840 1175-5326 2637282 04CF13A5-74CE-42E6-98B3-6FBB9BABE601 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.
