Abstract
The long-armed scarab (Cheirotonus gestroi) is an endangered large insect in southwestern China and neighboring countries; however, limited information is available regarding its population genetics, hindering conservation efforts. Therefore, we investigated the population genetic structure and evolutionary history of C. gestroi in southwestern China. Twenty-five haplotypes were obtained from 47 specimens across five populations. The Dawei Mountain (DWS) population differed from other populations by a high genetic distance. Population structure analysis generated three distinct clades, corresponding to Hengduan Mountains (HM), Ailao Mountains (AM), and Dawei Mountains (DM), and high-level genetic diversity was found in two HM populations. Collectively, the strong genetic differentiation among populations might be due to limited gene flow, geographical isolation, and habitat fragmentation. Therefore, while developing a conservation strategy, HM, AM, and DM groups should be defined as separate management units. Additionally, the DWS population should be given priority protection due to its uniqueness and low genetic diversity.
