description
(Table 1, Figures 1 – 3) Description of the new species Animals (measurements and statistics in 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. 1 B). 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). Microplacoid and septulum absent (Fig. 1 A – C). Claws of the Hypsibius type, small, without sutures or light-refracting units and pseudolunulae (Fig. 2), but with accessory points on primary branches (Fig. 3 D). Cuticular bars under claws absent. Eggs: Not found. DNA sequences The 18 S rRNA marker was sequenced for both individual and pooled tardigrades, but COI was successfully sequenced only from one individual tardigrade. All 18 S rRNA sequences represented a single haplotype (MK 387067) and the sequence was 1716 bp long whereas the COI sequence (MK 392633) was 658 bp long (the sequences are also provided in the Appendix 1).
etymology
Etymology. The new species is named after the Wuying district of Yichun, China, where it was discovered. Type depositories. The holotype (IAE 036451) and one paratype (IAE 036452) are deposited at the Herbarium of Institute of Applied Ecology, CAS, Shenyang. Four paratypes (NMS 0001 – 4) are deposited at the Microbiological Lab, College of Life Sciences, Northeast Forestry University, Harbin.
