Remarks: New hosts and locality records. Referred to as Genarchella szidati Yamaguti, 1971 by Hamann (1989). Hamann (1989) indicated that the records of Genarchella parva in Auchenipterus nuchalis , Jenynsia lineata and Pimelodella howesi , in Argentina probably correspond to A. osteomystax , J. multidentata and P. mucosa , respectively (see Liotta, 2005; Aguilera & Azpelicueta, 2015; Froese & Pauly, 2016).
