Comments: this ascaridid was firstly described as a subgenus of Multicaecum by Mozgovoy, in Skrjabin, Shikobalova and Mozgovoy (1951). After, Sprent (1979) validated Brevimulticaecum as genus. Ten species have distribution through Africa, Americas, and Oceania, and five have been reported in crocodilians ( Vieira et al. 2010). Freshwater rays and teleosts are considered as definitive hosts, and encysted larvae can be associated with amphibians, snakes, and freshwater fishes ( Sprent 1979; Moravec & Kaiser 1994; Anderson 2000; Vieira et al. 2010). We observe the the main features of the larvae of Brevimulticaecum such as the lack of dentigerous ridges on lips, the presence of short ventricular appendices and the peculiar position of excretory pore and excretory nucleus ( Moravec & Kaiser 1994; Vieira et al. 2010). Recent studies such as Campi„ o et al. (2016), Graça et al. (2017), Martins-Sobrinho et al. (2017) and Silva et al. (2018) added several anuran species belonging to Hylidae and Leptodactylidae families as hosts for larvae of Brevimulticaecum . Here, we present new records for P. platensis , P. marmoratus , P. nattereri , and R. diptycha .
