Identification of a New Record Species of Calamaria jinggangensis in Guangxi,China,with Phylogenetic Relationship Analysis of the Species
Calamaria jinggangensis Cai,2023,which belonging to the family of Colubridae,was only known to be distributed in Jinggang Mountains,Jiangxi,China.On September 3,2021 and June 2,2022,two specimens(No.GXNU20210909007 and GXNU20220613012)presented similar morphological features with C.jinggangensis were collected from Guilin,Guangxi Zhuang Autonomous Region.Phylogenetic analysis based on the mitochondrial cytochrome b(cyt b)gene showed that specimens from Guilin clustered into a single unit with the type specimen of C.jinggangensis.Genetic distance between the collected samples and C.jinggangensis was 0.005-0.030,significantly smaller than the genetic distance between other species within the genus Calamaria 0.052-0.237.Through morphological comparison and phylogenetic analysis,it is confirmed that the two specimens are C.jinggangensis which belongs to the genus Calamaria.This discovery is the first record of this species in Guangxi,which could provide more information on the geographic distribution and phylogeny of Calamaria species.
