New Distribution Record of Hynobius maoershanensis
Hynobius maoershanensis is known to be only distributed in the Guangxi Maoershan National Nature Reserve.In March 2022,a specimen of Hynobius was collected in the Quanzhou Tianhu National Wetland Park(26°6′21″ N,110° 54′14″ E;1,680 m),Guilin City,Guangxi Zhuang Autonomous Region,which was identified as H.maoershanensis.This is the second new record of distribution after the first records in the Maoershan Nature Reserve in 2006.Phylogenetic analy-sis based on mitochondrial 16S rRNA genes and COI gene show that the collected specimen clustered into monophyly with those from the Maoershan origin,with a genetic distance of 0.5%.The altitude distribution of H.maoershanensis was up-dated from above 1,966 m(previous record)down to 1,680 m above sea level,indicating this species has a broader eco-logical niche.This finding is of great significance for the scientific management and conservation of this species in the fu-ture.
