Description of the new species
Animals (measurements and statistics in Table 2 View TABLE 2 )
Body colourless and slender. Eyes absent (in live specimens) and the cuticle was smooth. Oral cavity armature not visible under PCM. Buccopharyngeal apparatus of the Diphascon type. Apophyses for the insertion of the stylet muscles hook-shaped. The buccopharyngeal tube with a drop-shaped formation on the buccal/pharyngeal tube boundary ( Fig. 1B View FIGURE 1 ). Muscle pharynx ovoid, with small pharyngeal apophyses and three macroplacoids in the shape of slender rods of increasing length from first to third, with the second clearly longer than the first (macroplacoid length sequence: 1<2<3; Table 2 View TABLE 2 ). Microplacoid and septulum absent ( Fig. 1 View FIGURE 1 A–C).
Claws of the Hypsibius type, small, without sutures or light-refracting units and pseudolunulae ( Fig. 2 View FIGURE 2 ), but with accessory points on primary branches ( Fig. 3D View FIGURE 3 ). Cuticular bars under claws absent.
Eggs: Not found.
DNA sequences
The 18S rRNA marker was sequenced for both individual and pooled tardigrades, but COI was successfully sequenced only from one individual tardigrade. All 18S rRNA sequences represented a single haplotype ( MK387067 View Materials ) and the sequence was 1716 bp long whereas the COI sequence ( MK392633 View Materials ) was 658 bp long (the sequences are also provided in the Appendix 1).
Type locality. 48º07.25’N, 129º11.19’E; 331 m asl: China, Heilongjiang Province, Wuying district of Yichun ; habitat: shady urban park; substrate: mosses on a fallen log. GoogleMaps
Etymology. The new species is named after the Wuying district of Yichun, China, where it was discovered.
Type depositories. The holotype (IAE036451) and one paratype (IAE036452) are deposited at the Herbarium of Institute of Applied Ecology, CAS, Shenyang. Four paratypes (NMS0001–4) are deposited at the Microbiological Lab, College of Life Sciences, Northeast Forestry University, Harbin.
