The Balkan Psorodonotus (Orthoptera: Tettigoniidae): Testing the existing taxa confirmed presence of three distinct species

Abstract

A review of the Balkan representatives of the genus Psorodonotus was made with the aim of revealing the relationships between taxa and their systematic arrangement. For this purpose we used morphological (qualitative and quantitavive), acoustic (amplitude-temporal song parameters) and molecular (mtDNA COI gene sequence) data. The analyses and comparisons with other taxa of Psorodonotus support the distinction of three species occurring on the Balkan Peninsula: P. fieberi, P. illyricus and P. macedonicus. Analysis of the COI sequences suggested the following relationships: outgroups + (P. illyricus + (P. fieberi + (P. macedonicus + P. caucasicus))). All available information on the distribution of the Balkan taxa was synthesized and mapped.
