Resumo

Dendrophryniscus brevipollicatus Jimenez de la Espada is a Neotropical bufonid endemic to a small range of the Brazilian Coastal Atlantic Forest, with reduced body size for the family and bromeligenous habit. We reviewed the taxonomic status of populations of D. brevipollicatus from states of Rio de Janeiro and Sao Paulo, including some continental islands, based on external morphology. We tested our morphological species by a DNA-barcoding approach with sequences of 16S RNA ribosomal gene fragment. DNA-barcoding analysis included other recognized Dendrophryniscus species and was concordant with morphological species diagnosed in our review. Intraspecific genetic distances ranged from 0 to 2.72 % (+/- 0.91 %). Interspecific distances ranged from 3.35 % (+/- 0.90 %) to 20.15 (+/- 2.23 %). Optimal threshold values ranged from 2.8 % to 3.0 % and barcode gap analysis showed that for all individuals the furthest intraspecific distances was always lower than the closest non-conspccific individual. Seven distinct species were recognized. A ncotype for D. brevipollicatus was designated and described; the type locality was determined for the Acude da Solidao (22 degrees 57'S, 43 degrees 17'W, Datum WGS 84; 410 m altitude), Parque Nacional da Tijuca, Municipality of Rio de Janeiro, State of Rio de Janeiro, Brazil. Two species were revalidated: D. imitator (Miranda-Ribeiro), with designation of a lectotype and descriptions of the lectotype and of a topotype from the restricted type locality, Alto da Serra (23 degrees 46'S, 46 degrees 19'W, Datum WGS 84, 800 m altitude), Municipality of Paranapiacaba, State of Sao Paulo, Brazil; and D. lauroi (Miranda-Ribeiro), with descriptions of the lectotype and of a topotype from the type locality, Municipality of Angra dos Reis (22 degrees 54'S, 44 degrees 20'W, Datum WGS 84; 25 m altitude), State of Rio de Janeiro, Brazil. Four new species were described: D. davori sp. nov., from Baixo Caledonia (22 degrees 21'S, 42 degrees 35'W, Datum WGS 84; 1600 m altitude), Municipality of Nova Friburgo, State of Rio de Janeiro, Brazil; D. haddadi sp. nov., from Parque Estadual da Senn do Mar, Nucleo Santa Virginia (23 degrees 21'S, 45 degrees 08'W, Datum WGS 84; 970 m altitude), Municipality of Sao Luis do Paraitinga, State of Sao Paulo, Brazil; D. izecksohni sp. nov., from Campo de Fruticultura da Bocaina (currently Nucleo Senador Vergueiro), Municipality of Sao Josd do Barreiro (22 degrees 38'S, 44 degrees 34'W, Datum WGS 84, 540 m altitude), State of Sao Paulo, Brazil; and D. jureia sp. nov., from Estacao Ecologica da Jurdia-Itatins-Nucleo Rio Verde (24 degrees 22'S, 47 degrees 04'W, Datum WGS 84; 32 m altitude), Municipality of Iguape, State of Sao Paulo, Brazil. Geographical distributions of all species are provided. (AU)
