We describe a new species of the Scinax ruber clade from Northeastern Brazil that occurs in widely separated geographic areas in the Atlantic Forest of southern Bahia state and the Highland Humid Forest of Serra de Baturité, northeast Ceará state. Scinax tropicalia sp. nov. is diagnosed from all 75 currently recognize species of the S. ruber clade by bioacoustical and morphological adult traits, such as duration (0.11–0.31 s) and dominant frequency (1.59–1.85 kHz) of the advertisement call, snout shape rounded, nearly rounded, or semi-circular in dorsal view and rounded to slightly protruding in profile, bilobate vocal sac, absence of pectoral glands and spicule-shaped papillary epidermal projections on nuptial pads, and color pattern on the dorsum of body and hidden surfaces of hindlimbs.

Scinax tropicalia sp. nov.
Diagnosis. The new species is diagnosed by the following combination of characters: (1) male SVL 30.8–39.7 mm, n = 48; (2) snout rounded, nearly rounded, or semi-circular in dorsal view and rounded to slightly protruding in profile; (3) tympanum diameter about half size of eye diameter (TD/ED = 0.50 ± 0.054); (4) pointed tubercles on heel and lower jaw absent; (5) vocal sac bilobate, subgular; (6) slightly thick nuptial pad covering the Metacarpal II dorsomedially, and obscuring the outer margin of the thenar tubercle ventrally; (7) spicule-shaped papillary epidermal projections absent on the nuptial pad; (8) pectoral glands absent in males; (9) moderately developed pre- and postaxial webbing of Toe IV, reaching the proximal half of the penultimate phalanx; (10) dorsal pattern consisting of a brown background with two continuous or discontinuous longitudinal darker brown blotches, and an interocular marking; (11) in living specimens, color pattern of hidden surfaces of thighs, shanks, and tarsi consisting of medium to large size, rounded or irregular, dark brown blotches in a white, light blue, light green, light purple, or light yellowish-green background; (12) iris bronze with dark reticulations in living specimens; (13) physiological chlorosis absent; (14) advertisement call composed of a multipulsed note of duration 0.11–0.31 s, 8–20 pulses per note, pulse rate of 61–73 pulses/s, and dominant frequency of 1.59–1.85 kHz.
Etymology. The specific epithet, a noun in apposition, is in allusion to the tropical habitat where the new species occurs, and also in homage to the Brazilian revolutionary artistic movement known as Tropicália, or Tropicalismo. This cultural movement arose in the late 1960s and had among its famous members the musicians from Bahia, Caetano Veloso, Gilberto Gil, Gal Costa, and Tom Zé, among other artists. The “tropicalists” introduced many aesthetical innovations and mixed a myriad of elements and rhythms from diverse origins (national and for-eign, traditional and avant-garde, popular and erudite). This movement was formally disintegrated in 1968 with the prison and exile of Caetano Veloso and Gilberto Gil by the authoritarian military dictatorship that ruled Brazil from 1964 to 1985. Tropicália certainly has marked and influenced the Brazilian popular culture over the years from its genesis. For more details about Tropicália, see Veloso & Dunn (1996), Favaretto (2000), Dunn (2001, 2014), Veloso (2017), and Oliveira (2020).
