A taxonomic revision and species delimitation of the genus Purpuraria Enderlein, 1929 (Orthoptera: Pamphagidae) using an integrative approach
Recent studies on the endemic Canarian genusPurpurariahave shown that the taxonomy of its only recognized species (P. erna) is probably errone-ous. In this study, an integrative revision of the genus is performed, based on a large number of specimens and geographical sampling. As a result, (1)the diagnostic characters at the genus level are re-described, (2)Purpuraria magnan. sp. based on morphological, morphometric and genetic data isdescribed and (3) the taxonomic status of a formerly described subspecies is clarified. Intraspecific and interspecific morphometric differences havebeen found, indicating that the genus is undergoing a process of morphological diversification. Nevertheless, the possibility of interspecific matingbetween individuals of the two species is suggested, because no significant differences have been found between their respective calling songs. Geneticanalyses using mitochondrial and nuclear DNA sequences suggest thatP. ernaandP. magnaare recent species with evidences of secondary contactepisodes in the past.
