<jats:p>Abstract: During a taxonomic study of the genus Notodiaptomus Kiefer 1936, taxonomic materials were located for N. iheringi, N. spinuliferus, N. henseni and N. deitersi, and all had their status investigated. Inconsistencies were found and are reported in this note, from the original details to the current typological situation. Nomenclatural conformations and new types are specified. These reinforce the taxonomic validity of the species, recently redescribed in other research. Thus in this note the neotype to N. iheringi, N. spinuliferus, and N. henseni, and provide a topotype to N. deitersi are defined.</jats:p>
