The first European records of the pantropical genus Bambara Vuillet, and a review of the immigrant featherwing beetles in Europe

摘要

The Nearctic featherwing beetle Bambara fusca (Dybas, 1966) and the pantropical B. contorta (Dybas, 1966) are reported from north-western Germany, being the first European records of the genus Bambara VUILLET, 1911 (Coleoptera: Ptiliidae). They are regarded as recent immigrants, possibly introduced by the import of sawmill products. Diagnostic characters are briefly described, illustrated and keyed, and an extension of the key to the Central European genera of Ptiliidae by Besuchet (1971) is given. The 14 Bambara species of the world are tabulated with their distribution known so far. Previous introductions of 11 farther ptiliid species into Europe are summarized and discussed and the oldest known records, or the references referring to such, are accounted for. Parthenogenesis by European species of Ptiliidae is shown to be statistically highly correlated with immigration (P< 0.001) and, thus, a powerful tool for dispersal. Ptinella johnsoni RuTANEN is reported from Norway, Baeocrara japonica (MATTHEWS) from Belarus and Slovakia, and Acrotrichis insularis (Maeklin) from the Czech Republic for the first time.
