Nova espécie de Dendrophryniscus da região Amazônica (Amphibia, Anura, Bufonidae)

Abstract

ABSTRACT. NEW SPECIES OF DENDROPHRYNISCUS FROM AMAZONIC REGION (AMPHIBIA, ANURA, BUFONIDAE) .Dendrophryniscus bokermanni, sp.n. is described from Amazonic Region. It is related to D. minutus but it differs by the larger first finger and body length. KEY WORDS. Amphibia, Anura, Bufonidae, taxonomy of frogs, new species Cerca de onze diferentes nomes específicos ou sub-específicos já foram inclui dos, segundo a literatura, no gênero Dendrophryniscus, mas presentemente apenas três permanecem aceitos para formas desse gênero (FROST, 1985), respectivamente D. brevipollicatus Jimenez de la Espada, D. /eucomystax Izecksohn eD. minutus (Mellin). As duas primeiras espécies ocorrem na floresta atlântica e a última é forma amazÔnica. No presente trabalho é apresentada a descrição de uma nova espécie da Região Amazônica. MATERIAL E MÉTODOS Foram examinados 75 exemplares pertencentes às seguintes coleções:Museu Nacional (MN), no Rio de Janeiro, Werner c.A. Bokermann (WCAB), em São Paulo, e do Autor (EI), depositada na Universidade Federal Rural do Rio de Janeiro, em Itaguaí. Uma coluna vertebral foi examinada e, para isso, foi a mesma retirada do exemplar e limpa dos tecidos moles com o emprego de hipoclorito de sódio.Dendrophryniscus bokermanni, sp.n. Figs 1-12Diagnose. Espécie com as extremidades dos dedos pouco dilatadas, com máculas enegrecidas no ventre e manchas dorsais confluentes, apresentando os machos antebrados espessos e mãos com o I dedo maior do que o II, e possuindo as fêmeas óvulos pigmentados, pequenos e numerosos.

Uncovering the diversity in the Amazophrynella minuta complex: integrative taxonomy reveals a new species of Amazophrynella (Anura, Bufonidae) from southern Peru

“…From Amazophrynella bokermanni (Fig. 6B) relative size of fingers, with finger I shorter than II (I>II); snout vent length smaller in males (15.8 mm) and females (22.25 mm) ( Amazophrynella bokermanni with maximum 22 mm SVL in males and 28 mm SVL in females, see Izecksohn 1993); smaller snout in males, with 2.2 mm SL, n = 26 (2.7 mm SL, n = 5; see Table 1); posterior side of belly color pale orange yellowish with tiny rounded black or dark brown spots (white coloration with small black dots). From to Amazophrynella vote (Fig.…”

A new species of Amazophrynella (Anura:Bufonidae) from the southwestern part of the Brazilian Guiana Shield

“…In addition to this material we analyzed five specimens of Amazophrynella bokermanni (Izecksohn, 1993) from near the type locality deposited in the Collection of Amphibians and Reptiles of the Instituto Nacional de Pesquisas da Amazônia-INPA, Manaus, Amazonas, Brazil (INPA-H), the holotype of Amazophrynella vote Ávila, Carvalho, Gordo, Kawashita & Morais 2012, deposited in the Coleção Zoológica de Vertebrados of the Universidade Federal de Mato Grosso-UFMT, Cuiabá, Mato Grosso, Brazil (UFMT-A) and seventeen A. vote paratypes deposited in the Collection of Amphibians and Reptiles of the Instituto Nacional de Pesquisas da Amazônia-INPA, Manaus, Amazonas, Brazil (INPA-H). List of specimens examined is found in Appendix 1.…”

“…Amazophrynella Fouquet, Recoder, Teixeira, Cassimiro, Amaro, Camacho, Damasceno, Carnaval, Moritz, & Rodrigues 2012, is a genus of small, early diverging bufonid frogs (Pramuk et al, 2008;Bocxlaer et al, 2010). The genus is currently represented by three nominal species: Amazophrynella minuta (Melin, 1941), A. bokermanni (Izecksohn, 1993) and A. vote Ávila, Carvalho, Gordo, Kawashita & Morais, 2012(Frost, 2013. All species of Amazophrynella present a clear sexual size dimorphism, reproduce in seasonal puddles and share this characteristic only with Dendrophryniscus leucomystax (Izecksohn, 1968).…”

All species of Amazophrynella present a clear sexual size dimorphism, reproduce in seasonal puddles and share this characteristic only with Dendrophryniscus leucomystax (Izecksohn, 1968). Their exclusive habitat is leaf litter and they have a diurnal activity (Magnusson & Hero, 1991;Lima et al, 2006;Ávila et al, 2012).…”

“…We examined topotypical material of Amazophrynella minuta deposited at the collection of Amphibians and Reptiles of the Instituto Nacional de Pesquisas da Amazônia-INPA (INPA-H) and three syntypes (NHMG 462,NHMG 463,NHMG 464) deposited at the Göteborgs Naturhistoriska Museum, Sweden; five specimens of A. bokermanni (Izecksohn, 1993) from near the type locality (c. 30 Km) deposited at the INPA collection; the type series of A. vote (Ávila et al, 2012) deposited at the Coleção Zoológica de Vertebrados of the Universidade Federal de Mato Grosso-UFMT, Cuiabá, Mato Grosso, Brazil (UFMT-A) and INPA; A. manaos deposited at the INPA; A. amazonicola and A. matses (Rojas et al, 2015) deposited at the Museo de Zoología-Universidad Nacional de la Amazonia Peruana-UNAP and A. javierbustamantei (Rojas et al, 2016) deposited at the Museo de Biodiversidad del Peru (MUBI), Museo de Historia Natural de la Universidad Nacional Mayor de San Marcos (MHNSM).
