We describe the tadpole morphology, the advertisement and courtship calls, and reproductive characteristics of Rupirana cardosoiHeyer 1999, an endemic species from rocky mountain fields in Chapada Diamantina, Bahia State, Brazil. Females of Rupirana cardosoi deposit pigmented eggs in shallow backwaters or ponds. The body of tadpoles is ovoid in dorsal and ventral views and depressed in lateral view. The oral disc is ventral and the labial tooth row formula is 2(2)/3(1). Eyes are dorsal. The advertisement call has one pulsed note, with dominant frequency approximately 1.3 kHz. The courtship call presents three note types with dominant frequency ranging from 0.7 to 1.4 kHz. Females are larger ( = 34.4, SD = 1.6, 31.4–37.4 mm, n = 12) than males ( = 30.9, SD = 1.5, 28.8–33.8, n = 9; t = 5.1; p < 0.001) and males present nuptial excrescences located on the base of the thumbs. The eggs are medium sized ( = 2.47 ± 0.52 mm, N = 27) and mean clutch size was 120.44 ± 74.38 eggs (N = 11 clutches).
