摘要： Clarifying the geographic patterns of species diversity and the determinant factors can provide essential information for species conservation and management. Stag beetles (Coleoptera: Lucanidae) ofLucanusare important saproxylic insects and can be used for biomonitoring forests. Most ofLucanusspecies are facing conservation concerns due to their limited distribution and fragmented habitats, particularly in China, which has the richest species diversity of this genus. The distribution patterns of species diversity ofLucanusat large spatial scales remain portly understood. We studied the distribution patterns ofLucanusand its environmental and geographic determinants in China. Distribution data for 72 species and subspecies were examined. All these species are distributed in southern China except forLucanus maculifemoratus dybowskyi, which is mainly distributed in north China. The hotspot forLucanusin China is southeastern Tibet. Our study indicated that the species richness ofLucanusin China was shaped by the precipitation of the wettest and driest month, net primary productivity, digital elevation model, and latitude at a large scale. These variables collectively explained 56.2% of the variation in species richness; precipitation contributed the most (44.1%). Our results provide valuable insights to improve the conservation ofLucanusand can contribute to furthering our understanding of the biogeography of stag beetles in China.
