RESUMO
Some corrections to the section of subtribe Bembidiina of the Catalogue of Palaearctic Coleoptera, Vol. 1, together with geographic, systematic, and synonymic updates are reported and commented upon. The following five new synonymies are proposed (with junior synonym listed first): Bembidion (Peryphanes) dostali Kirschenhofer, 1984 = Bembidion (Peryphanes) sanatum Bates, 1883 syn. nov.; Bembidion (Terminophanes) pseudoconsumatum Kirschenhofer, 1984 = Bembidion (Terminophanes) sjoelanderi Jedlicka, 1965 syn. nov.; Bembidion (Asioperyphus) sapporense Jedlicka, 1951 = Bembidion (Politophanes) chloreum Bates, 1873 syn. nov.; Bembidion (Peryphus) torosiense Jedlicka, 1961 = Bembidion (Peryphus) subcostatum vau Netolitzky, 1913 syn. nov.; Sinechostictus (Sinechostictus) multisulcatus cariniger Korge, 1971 = Sinechostictus (Sinechostictus) multisulcatus (Reitter, 1890) syn. nov. Furthermore we confirm the following synonimies: Asaphidion weiratheri Netolitzky, 1935 = Asaphidion ganglbaueri J.Müller, 1921; Sinechostictus (Sinechostictus) effluviorum (Peyron, 1858) = Sinechostictus (Sinechostictus) tarsicus (Peyron, 1858). The following nine new combinations are proposed: Bembidion (Euperyphus) dimidiatum Ménétriés, 1832 comb. nov.; Bembidion (Peryphus) psuchrum Andrewes, 1922 comb. nov.; Bembidion (Plataphus) pseudolucillum Netolitzky, 1938 comb. nov.; Bembidion (Politophanes) chloreum Bates, 1873 comb. nov.; Bembidion (Politophanes) gotoense Habu, 1973 comb. nov.; Bembidion (Politophanes) shunichii Habu, 1973 comb. nov.; Bembidion (Politophanes) umeyai Habu, 1959 comb. nov.; Bembidion (Politophanes) yoshidai Morita, 2009 comb. nov.; Bembidion (Terminophanes) sjoelanderi Jedlicka, 1965 comb. nov. The species Bembidion psuchrum Andrewes, 1922 and Bembidion sanatum Bates, 1883 are here redescribed.
RESUMO
As molecular identification method, DNA barcoding based on partial cytochrome c oxidase subunit 1 (COI) sequences has been proven to be a useful tool for species determination in many insect taxa including ground beetles. In this study we tested the effectiveness of DNA barcodes to discriminate species of the ground beetle genus Bembidion and some closely related taxa of Germany. DNA barcodes were obtained from 819 individuals and 78 species, including sequences from previous studies as well as more than 300 new generated DNA barcodes. We found a 1:1 correspondence between BIN and traditionally recognized species for 69 species (89%). Low interspecific distances with maximum pairwise K2P values below 2.2% were found for three species pairs, including two species pairs with haplotype sharing (Bembidion atrocaeruleum/Bembidion varicolor and Bembidion guttula/Bembidion mannerheimii). In contrast to this, deep intraspecific sequence divergences with distinct lineages were revealed for two species (Bembidion geniculatum/Ocys harpaloides). Our study emphasizes the use of DNA barcodes for the identification of the analyzed ground beetles species and represents an important step in building-up a comprehensive barcode library for the Carabidae in Germany and Central Europe as well.
