| Abstract: |
| Tardigrada is a kind of micro aquatic invertebrate multicellular animal, which is a unique phylum in systematic classification and has close relationship with arthropod. At present, there are more than 1 250 species in more than 110 genera, 13 families, 5 orders and 3 classes. This paper briefly introduces the progress of systematic classification of Tardigrada in Shaanxi Province, and preliminarily analyzes the taxonomic composition of Tardigrada in Shaanxi Province. There are 107 species of Tardigrada in Shaanxi Province, which belong to 2 classes, 3 orders, 4 families and 17 genera. In addition, the research methods, direction and significance of systematic classification of the Tardigrada in Shaanxi Province are prospected. |
