The call of the species has been previously described, but recently gathered data revealed an unreported acoustic unit that we describe herein. Intraspecific variation within the species call was also updated based on an increased sample size. The call is composed of two types of multipulsed notes: a short note, which is in agreement with the previous description, and a trill note that is emitted in association with the short note. The trill note was likely not reported in the previous description because of the small sample size. Further studies should elucidate the social function of the trill note. Acoustic units somewhat resembling the trill note are shared by a few other Scinax species, but the nomenclatural instability of these calls hamper detailed comparisons. This highlights the need for a standardized and comparative acoustic analysis to elucidate homologous and comparable acoustic units among the bromeligenous Scinax species.

Mycobacteriosis is a bacterial disease of animal and human importance. Mycobacterium gordonae infects the skin and internal organs of free-ranging amphibians and is considered the least pathogenic member of the Mycobacteriaceae to humans. However, information about its infection and pathogenesis in wild amphibians is still lacking. A total of 1306 amphibian specimens belonging to 6 families, 12 genera, and 21 species were collected and dissected during a helminthological survey of 7 municipalities in southern Ceara state, Caatinga (eco)region, northeast Brazil. Of these, 17 specimens (0.76%), belonging to 2 families and 4 species (Leptodactylus macrosternum, n = 2; L. vastus, n = 10; Pseudopaludicola pocoto, n = 2; Rhinella jimi, n = 3), presented infections that consisted of calcification nodules in the coelomic cavity, kidney, liver, lung, gut, and pancreas. The nodules were examined by histopathology and PCR. The bacteria were identified as M. gordonae by molecular analyses. Infected animals presented with hepatocellular vacuolar degeneration, karyolysis, and karyorrhexis, hepatic portal congestion, hemorrhage, mononuclear cellular infiltration, melanomacrophage center hyperplasia, and granulomas in varying stages of development with intralesional acid-fast bacilli. This study is the first report of M. gordonae in these amphibian species, in which results of molecular analyses confirmed the presence of M. gordonae in natural environments and histopathology confirmed the typical lesion of mycobacteriosis in amphibians from northeastern Brazil.
