New Insight into the Systematics of European Lepidocyrtus (Collembola: Entomobryidae) Using Molecular and...

The Collembolan genus Lepidocyrtus is subdivided into up to eight subgenera, of which only Lepidocyrtus s.str. (Bourlet, 1839) and Lanocyrtus (Yoshii & Suhardjono, 1989) are represented by European species. The discovery of unique characters in the European species Lepidocyrtus tomosvaryi (rounded dental tubercle) and L. peisonis (lateral tuft of long filiform chaetae in abdomen III) has only described so far for species of the subgenera Setogaster (Salmon, 1951) and Cinctocyrtus (Yoshii & Suhardjono, 1989) and has raised the need to perform a molecular analysis by involving other representative species of the genus. For this study, phylogenetic analysis of 15 Lepidocyrtus species occurring in the Carpathian Basin were carried out. The analyses, which was based on both concatenated datasets of COII and EF1-α sequences and individual gene sequences, clearly placed L. tomosvaryi within the subgenus Lanocyrtus and L. peisonis within Lepidocyrtus s.srt. European species groups defined on the basis of morphological characters were only partly confirmed by the concatenated and COII analyses because of the splitting of the pallidus-serbicus-group, whereas EF1- α sequences weakly supported this group.
