Three new species and two new genera of tube worms are described from the Upper Anisian (Middle Triassic) of the vicinity of Qingyan, Guizhou Province, south-western China. Small Ruxingella lianjiangensis n. g. n. sp. and tiny Weixiserpula weixi n. g. n. sp. both belong to the Serpulidae. The Spirorbidae are represented by "Spirorbis" qingyani n. sp. These tube worms lived in a shallow-marine habitat and were cemented to biogenic hard substrates. Small Trypanites ichnosp. show that polychaetes boring into hard substrate were present as well. Serpula pygmaea Münster 1841 is a junior primary homonym and is renamed Weixiserpula? cassiana n. nom.
