An updated checklist of Chiroptera in Guangdong Province and a molecular barcode database

Aims: Guangdong Province is one of the provinces with the high diversity of Chiroptera in China and is also one of the global hotspots for chiropteran distribution.To comprehensively understand the current diversity resources of Chiroptera in Guangdong Province, and to provide basic data for future biodiversity research and conservation practices, the timely updating of species checklists and the availability and accuracy of molecular barcode databases, even those based on local species specimens, are necessary.Methods: This study was based on our long-term survey results over 30-years effort, combined with a summary of historical records and literature on Guangdong Province, we aimed to update the chiropteran species checklist for the province.Additionally, we selectively utilized our specimen resources that collected by our research team over 30-years to specifically construct their molecular barcode database via molecular barcoding technology.We provided primers and PCR systems for molecular barcoding technology that cover the known species of Chiroptera, facilitating future use by researchers.
