Data from: A multivariate study of differentiating characters between three European species of the genus Lasiochernes Beier, 1932 (Pseudoscorpiones, Chernetidae)

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 L. cretonatus Henderickx, 1998, L. jonicus (Beier, 1929) and L. pilosus (Ellingsen, 1910) are presented. The female of L. cretonatus and the nymphs of L. pilosus 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.

本研究对毛伪蝎属（Lasiochernes Beier, 1932）下3种极难采集的欧洲物种的形态变异开展了全面分析。针对L. cretonatus Henderickx, 1998、L. jonicus (Beier, 1929)与L. pilosus (Ellingsen, 1910)，本研究详细记述了此前被忽视的形态特征。本研究首次描述了L. cretonatus的雌性个体及L. pilosus的若虫阶段。研究采用多元形态测量技术（主坐标分析（principal coordinate analysis）与判别分析（discriminant analyses）），验证了这3个毛伪蝎属物种的形态分化，并筛选出用于物种区分的最可靠特征。本研究评估了特定躯体部位在物种鉴定中的应用价值，同时提供了本次研究涉及的毛伪蝎属雌性物种的鉴定检索表，并总结了这3个物种的地理分布与栖息偏好。
