摘要

Morphological variation in three rarely collected European species of the genus Lasiochernes Beier, 1932 is thoroughly examined in the present study. Detailed descriptions of previously ignored morphological characters of Lasiochernescretonatus Henderickx, 1998, Lasiochernesjonicus (Beier, 1929) and Lasiochernespilosus (Ellingsen, 1910) are presented. The female of Lasiochernescretonatus and the nymphs of Lasiochernespilosus are described for the first time. Multivariate morphometric techniques (principal coordinate analysis and discriminant analyses) were employed to confirm morphological differentiation of the three Lasiochernes species and to identify the most reliable characters for their separation. The usefulness of particular body parts for species identification was evaluated. An identification key for the females of the Lasiochernes species studied is provided. Geographic distribution and habitat preferences of the three species are summarized.
