A new species of tardigrade, Crenubiotus liangshuiensis sp. nov. (Eutardigrada: Parachela: Macrobiotoidea: Adorybiotidae), was identified by combining DNA barcoding and classical morphological analyses (including both light contrast microscopy and scanning electron microscopy) of animals and an egg found in moss Collected in Yichun Liangshui National Nature Reserve. Moreover, nucleotide sequences of the 18S rRNA and COI markers from used to analyse the diversity of the local tardigrade fauna indicated the presence of at least 16 species representing 11 genera.
