The Scinax catharinae clade comprises the S. perpusillus and S. catharinae groups. The S. catharinae group has 38 species, mostly from Brazil's Atlantic Forest. We describe a new species of S. catharinae group based on external morphology, color pattern, and bioacoustics. The new species calls from herbaceous vegetation of slow-flowing streams from Santa Teresa, State of Espírito Santo, southeastern Brazil. The new species is distinguished from species of the S. catharinae group by the following combination of characters: male SVL 24.8–28.3 mm and female SVL 31.2–38.6 mm; males with hypertrophied forearms and inguinal glands; interocular region with a dark blotch not exceeding beyond the anterior margin of tympanic level; black blotches on a whitish-green background on the inguinal region and hidden surfaces of legs; call type A of 0.301–0.883 s, and 12–30 notes emitted at a rate of 31.4–42.0 notes/s. We also provide remarks on its natural history and conservation status.

Scinax pixinguinha, new species
Etymology.— Alfredo da Rocha Vianna Filho (1897–1973), popularly known as Pixinguinha, was a Brazilian musician and the most famous Choro player. Choro or Chorinho is a Brazilian genre of popular music originated in the 19th century. In Portuguese Choro or Chorinho means ‘‘cry’’ or ‘‘little cry,’’ respectively. Ironically, Chorinho is a contagious music commonly played during joyous moments in Brazil. Brazilians usually say Pixinguinha was a kind of magician who learned how to convert tears of Choro (cry) into tears of happiness. Because 72% of the Atlantic Forest original cover has been deforested, discoveries of new species also has the power to momentarily change part of our conservationist sadness into happiness and motivation. Thus, the specific epithet of S. pixinguinha is a noun in apposition in honor of the talented Brazilian musician—Pixinguinha.
