Three new genera including four new species of the bivalve family Mysidiellidae are described from late middle to early late Anisian (Middle Triassic) deposits of Qingyan, Guizhou Province, south‐west China. The new taxa Leidapoconcha gigantea gen. et sp. nov., Waijiaoella elegans gen. et sp. nov., Waijiaoella speciosa gen. et sp. nov. and Qingyaniola mirabilis gen. et sp. nov. significantly increase the known taxonomic diversity within the Mysidiellidae. These findings suggest a somewhat endemic evolutionary development within this small bivalve family during the Middle Triassic in south‐west China.
