No. of bitstreams: 0 Previous issue date: 2019-01-01 Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq) Universidade Estadual Paulista We describe a new species of Ischnocnema from the Serra da Bocaina mountain range, state of São Paulo, southeastern Brazil, based on morphological, bioacoustic, and mtDNA data. The new species is retrieved with high support values within the I. lactea species series as the sister species of I. spanios. Ischnocnema bocaina sp. nov. is characterized by its medium size (18.6–19.0 mm), a smooth venter, a rounded snout in dorsal view and acuminate in lateral view, a slightly expanded subgular, single vocal sac, a round and whitish, poorly-developed glandular-appearing nuptial pad on the dorsal surface of the thumb, and a nonpulsed advertisement call with 9 to 18 notes. We raise to 38 the number of Ischnocnema species, the 12th described in the past 10 years.

A new species of Paratelmatobius is described from the Brazilian Atlantic Forest in the state of Paraná in southern Brazil. Adults, tadpoles, and vocalizations are described. Morphological traits and phylogenetic analysis place the new species within the P. cardosoi group. The new species can be readily distinguished from its congeners by its advertisement call being composed of two note types and comprised of a series of 2–4 notes. The new species is classified as an explosive breeder, having reproductive activity strongly associated with heavy rainfall. This discovery highlights the importance of intensifying survey efforts in the Atlantic Forest, a domain with high levels of species richness and endemism.

We report new records for the poorly known species Hylodes babax (fourth record), Dendropsophus ruschii (fourth record) and Bokermannohyla ibitipoca (fifth record), from an Atlantic Forest fragment in the eastern region of the Mantiqueira mountain range in Minas Gerais, Brazil.

The present study describes for the first time the advertisement call of Ceratophrys joazeirensis Mercadal de Barrio, 1986. This rare explosive breeding species is endemic to the semi-arid Caatinga biome and is known only from four localities in northeastern Brazil: Municipality of Juazeiro, State of Bahia (type locality); Municipalities of Araruna and Triunfo, State of Paraíba; and Municipality of Passa and Fica, State of Rio Grande do Norte (Mercadal de Barrio, 1986; Vieira et al. 2006; Santos et al. 2009).
