ABSTRACT. A cladistic study of phylogeny was performed for four genera of the Aloninae (Cladocera: Anomopoda: Chydoridae) (Karualona, Kozhowia, Kurzia and Nicsmirnovius) using accessible literature data. The relationships between all known species within each genus are discussed. The boundary between the subgenera Kurzia (Kurzia) Dybowski & Grochowski, 1894 and Kurzia (Rostrokurzia) Hudec, 2000 does not follow the boundary between two main clades within the genus. This anomaly was improved by relocating K. media (Birge, 1879) into the subgenus K. (Rostrokurzia). Alona longirostris Daday, 1898 (= K. longirostris) is designated as the type species of the subgenus K. (Rostrokurzia) emend. nov. Emended diagnoses of two subgenera of Kurzia are provided. The patterns of inter-continental grouping of species are different for different genera.

KEY WORDS: Cladocera, Anomopoda, Chydoridae, Aloninae, morphology, systematics, phylogeny, cladistics.
