MtDNA haplotypes of Rhinolophus rex ssp. specimens in the NJ networks. The colours of mtDNA haplotypes of study specimens match their corresponding locations in Fig. 1 (sensu Burgin et al. 2020; Zhang et al. 2018, Chornelia et al. 2022). MtDNA haplotypes of some Chinese specimens of R. r. rex whose collecting locations are uncertain are indicated with an asterisk (C*) (Table S1).
