A New Species of Bryaxis (Coleoptera: Staphylinidae: Pselaphinae) from Mount Etna (Sicily, Italy) and Notes on Its Ecology and Distribution.

ABSTRACT: A new species of the subfamily Pselaphinae (Coleoptera: Staphylinidae) has been discovered on Mount Etna (Sicily, Italy) and is described herein as Bryaxis aetnensis sp. nov. The new species is closely associated with the Bryaxis difficilis group, a highly homogeneous group of species living in the regions of Sicily and Sardinia. Diagnostic features and distribution of Sicilian species of this group are treated and illustrated herein. Bryaxis aetnensis sp. nov. exhibits similarities to B. marinae but can be distinguished by the darker color, longer antennal scape and terminal palpomere, and in the aedeagus morphology. The distribution of B. aetnensis sp. nov. spans a wide altitudinal range, demonstrating a remarkable climatic tolerance across the slopes a
