Aspidytidae is a family of aquatic beetles of the suborder Adephaga, described in 2002 from specimens in South Africa and China.[2] There are only two known species in the family and these were originally described in the genus Aspidytes,[2][3] but later the new genus Sinaspidytes was erected for the species found in China.[4] The family can also be referred to by its trivial name cliff water beetles.[5]
