Cosmocerca parva Travassos 1925 (Ascaridida, Cosmocercoidea, Cosmocercidae) wasoriginally described from Helosia nasus (Leptodactylidae) of Angra dos Reis, State of Riode Janeiro, Brazil. It has also been reported in Leptodactylus chaquensis, L. elenae, Hylafuscovaria and Bufo paracnemis from Paraguay (MR Baker & C Vaucher 1984 Rev Suisse Zool91: 299-307).This note enlarges the known morphological variability of C. parva in a new host and makesamend for previous descriptions with the aid of scanning electron microscope (SEM) at the sametime that presents the first record of Cosmocerca species in Argentina.
