Abstract

Only three saproxylic species of Pyrochroinae (Coleoptera: Pyrochroidae) are distributed in Europe, two of which belonging to Pyrochroa: P. coccinea and P. serraticornis. However, P. serraticornis is polytypic, for the presence of the endemic subspecies P. s. kiesenwetteri in southern Italy. Using both molecular and morphological data, we explored the phylogeny of the European Pyrochroa species. A multilocus (COI, CAD, 28S) phylogenetic analysis helped highlight different evolutionary histories for the two examined species. First, P. coccinea, distributed throughout Europe, showed a high differentiation among Italian and European populations. Furthermore, three different taxonomic entities were identified within P. serraticornis, among which the cryptic species Pyrochroa bifoveata sp. n. from central Europe is described and illustrated. A comprehensive identification key to the European Pyrochroinae is also provided. Our results also suggested an historical survival of P. coccinea and P. s. kiesenwetteri in glacial refugia in Italy, and a subsequent post-glacial spread of the former species throughout the Peninsula. In contrast, the current distribution of P. s. serraticornis likely originated from a post-glacial colonization of western European relict populations, while the survival of P. bifoveata plausibly occurred in more eastern glacial refugia (e.g. Carpathian or Balkan regions). Similarly, the European populations of P. coccinea could have originated from relict populations in glacial refugia out from the Italian Peninsula. More comprehensive data on the taxonomy, ecology and biogeography of Pyrochroa are needed to learn more about these species and to help preserve the European saproxylic fauna.
