Nova espécie de Melanophryniscus (Anura, Bufonidae) da região dos Campos Gerais, sul do Brasil

Abstract

A new species of Melanophryniscus (Anura, Bufonidae) from the Campos Gerais region of Southern Brazil. A new species of Melanophryniscus is described from the Parque Estadual de Vila Velha, municipality of Ponta Grossa, Paraná State, Southern Brazil. The Parque Estadual de Vila Velha is located in the Campos Gerais region, an environment dominated by natural grasslands with patches of Araucaria Forest. The new species is distinguished from all congeners by its small size (12.8-14.0 mm snout-vent length in adult males) and unique color pattern of copper brown dorsum covered with small spinulose black warts; ventral surface black finely spotted with white, posterior abdomen and ventral surfaces of the forearm, hand and foot with red stains. The new species is nocturnal and breeds in the water accumulated in the leaf-axils of phytotelmata.

Comparative morphology of pond, stream and phytotelm-dwelling tadpoles of the South American Redbelly Toads (Anura: Bufonidae:Melanophryniscus)

“…Recently, a new reproductive mode was described for the genus, and two species were found to breed in the water that accumulates in leaf axils of Eryngium spp. and bromeliads (Langone et al ., ; Steinbach‐Padilha, ). Although phytotelm dwelling is not rare in tadpoles, and several anuran families include species with this reproductive mode (Lehtinen, Lannoo & Wassersug, ), there are only a few bufonids known to exhibit this property; the report by Langone et al .…”

New record of Melanophryniscus biancae Bornschein, Baldo, Pie, Firkowski, Ribeiro & Corrêa, 2015 (Anura, Bufonidae) from Paraná, Brazil, with comments on its phytotelm-breeding ecology

“…Identification. There are only five phytotelm-breeding Melanophryniscus described so far, namely M. alipioi, M. biancae, M. milanoi, M. vilavelhensis, and M. xanthostomus (Langone et al 2008;Steinbach-Padilha 2008;Bornschein et al 2015). Some of the species have predominantly black and red ventral surfaces (M. alipioi, M. milanoi, M. vilavelhensis, and M. xanthostomus;Langone et al 2008, Bornschein et al 2015, while M. biancae has predominantly yellow ventral surface, with only a reduced tinge of red and small black dots (Bornschein et al 2015).…”

“…Oviposition in micro-waterbodies is represented by breeding in phytotelmata, a strategy described for M. alipioi Langone, Segalla, Bornschein & de Sá, 2008(Langone et al 2008. This reproductive mode was also described for a second species, M. vilavelhensis Steinbach-Padilha, 2008(Steinbach-Padilha 2008. More recently, three new species were described, all of them reproducing in phytotelmata, namely M. biancae Bornschein, Baldo, Pie, Firkowski, Ribeiro & Corrêa, 2015, M. milanoi Baldo, Bornschein, Pie, Firkowski, Ribeiro & Belmonte-Lopes, 2015, and M. xanthostomus Baldo, Bornschein, Pie, Ribeiro, Firkowski & Morato, 2015(Bornschein et al 2015.…”

“…These five species represent all the phytotelma-breeding Melanophryniscus. Another peculiarity of these species is their restricted geographical distribution, from a single locality to few localities in the states of Paraná and Santa Catarina, southern Brazil (Langone et al 2008;Steinbach-Padilha 2008;Bornschein et al 2015).…”

Novos registros na distribuição geográfica de anuros na floresta com araucária e considerações sobre suas vocalizações

“…Nos últimos anos, diversos estudos resultaram no registro de espécies antes desconhecidas para os Estados do Paraná (Bernarde 1998, Lingnau 2000, Lingnau & Bastos 2002, Machado & Conte 2001, Machado & Haddad 2001, Lima et al 2005, Conte et al 2009, Moresco et al 2009) e para Santa Catarina (Braun 1978, Garcia & Vinciprova 1998, Giasson et al 2001, Kwet 2004, Langone 1997, Lingnau & Di-Bernardo 2006. Esses resultados, juntamente com descrições de novos táxons (Castanho & Haddad 2000, Caramaschi & Cruz 2002, Baldissera et al 2004, Ribeiro et al 2005, Alves et al 2006, Caramaschi & Pombal 2006, Cruz et al 2008, Garcia et al 2008, Langone et al 2008, Steinbach-Padilha 2008 …”
