Incorrect catalogue numbers and incomplete information regarding types of Curimatus Oken of the Naturhistorisches Museum of Vienna (NMW) have been successively replicated in the ichthyology literature. Using evidence compiled directly from NMW types and data, this study formally presents the correct type numbers of Curimatus abramoides Kner 1858 (= Cyphocharax) and Curimatus knerii Steindachner 1876 (= Curimata) and clarifies the taxonomic status and availability of types of Curimatus elegans var. amazonica Steindachner 1911, Curimatus helleri Steindachner 1910, Curimatus surinamensis Steindachner 1910, and Curimatus naegelii Steindachner 1881.
