This study is based on the freshwater cladocerans collected in Taiwan, exc luding the offshore islands, from 1994 to 2006, Besides Chydoridae, we found 26 species (including one new species and 16 new recordings) in 13 genera: six species of Sididae : Sida crystalline (O,E Muller, 1776), Neodiaphanosoma celebensis (Stingelin, 1900), N volzi (StingeIin, 1905), Diaphanosoma dubium Manuilova, 1964, D, sarsi Richard, 1894, and D, excisum Sars 1855; one species of Bosminidae: Bosmina longirostris (O,E Muller, 1785); 12 species of Daphniidae: Scapholeberis kingi Sars, 1903, Daphnia similoides Hudec, 1991, D, cucullata Sars, 1862, D, obtusa Kurz,1874, D, ueno sp. nov" Simocephalus heilongjiangensis Shi and Shi, 1994, S, serrulatus (Koch, 1841), S, cf. vetulus (O,F. Muller, 1776), Ceriodaphnia cornuta Sars, 1885, C dubia Richard, 1894, C laticaudata Muller, 1867, and C quadrangular (O,F. Muller, 1785); three species of Moinidae: Moinodaphnia macleayi (King, 1853), Moina micrura Kurz, 1874, and M. macrocopa (Stra us, 1820); one species of Ilyocryptidae: Ilyocryptus agilis Kurz, 1878; and three species of Macrothricidae: Guernella raphaelis (Richard, 1892), Macrothrix spinosa King, 1853, and M. triserialis Brady, 1886. In this paper, we describe and illustrate each of the above-mentioned species, as well as provide a key to the families, genera, and species.
