Abstract

We describe a new species of the Dendropsophus decipiens Group, morphologically most resembling D. haddadi but genetically more closely related to D. oliveirai and likely endemic from the Atlantic Forest biome, northeastern Brazil. The new species can be distinguished from all species of the D. decipiens Group based on the combination of morphological features, advertisement call and phylogenetic position based on mitochondrial DNA gene sequences. The new species emits simple calls in series of 3–9 notes, each with 9–29 pulses, and dominant frequency varying from 5578–6422 Hz, and exhibit a minimum of 8% genetic distance (16S mitochondrial gene) in comparison to its congeners. The new taxa represent the sixth species of the D. decipiens Group, which likely harbors more undescribed taxa, corroborating the view that Neotropical species richness is fairly underestimated.

Highlights

IntroductionThe genus Dendropsophus Fitzinger, 1843 currently comprise 109 species broadly distributed across Neotropical rainforests and open areas from southern Mexico to northern Argentina and Uruguay, east of Andes [1]
Based on the recently published total evidence analysis of [2], combining phenomic and molecular datasets, nine species groups are currently recognized within this genus: D. ruschii, D. decipiens, D. parviceps, D. molitor, D. columbianus, D. marmoratus, D. minutus, D. leucophyllatus, and D. microcephalus
Apart from the D. decipiens Group, the presence of dorsolateral stripes that extends from the posterior region of the eye to the inguinal region and colored loreal region distinguishes D. tapacurensis sp. nov. from all species of D. microcephalus Group except D. tintinnabulum (Fig 1B of [50]), that may exhibit such pattern
