Uma nova espécie de Brachycephalus (Anura, Brachycephalidae) do estado do Rio de Janeiro

Abstract

A new species of

A new species ofBrachycephalus(Anura: Brachycephalidae) from Santa Catarina, southern Brazil

“…Brachycephalus albolineatus is distinguished from all species of the ephippium group whose members show dermal co-ossification, accordingly Ribeiro et al (2015), which is absent in the new species. Apart from the difference in coloration between the new species and all species of the ephippium group, it also differs in body size, which is larger in adults of the ephippium group, such as B. alipioi Pombal Jr & Gasparini, 2006 (SVL = 12.5–16.2 mm; Pombal Jr & Gasparini (2006)), B. crispus Condez, Clemente-Carvalho, Haddad & Reis, 2014 (SVL = 11.5–15.6 mm; Condez et al (2014)), B. margaritatus Pombal Jr & Izecksohn, 2011 (SVL = 15.0–18.9 mm; Pombal Jr & Izecksohn (2011)), B. pitanga Alves, Sawaya, Reis & Haddad, 2009 (SVL = 10.8–12.1 mm; Alves et al (2009)), B. toby Haddad, Alves, Clemente-Carvalho & Reis, 2010 (SVL = 11.3–14.2 mm; Haddad et al (2010)), B. vertebralis Pombal Jr, 2001 (SVL = 10.5–14.2 mm; Pombal Jr (2001)), B. nodoterga Miranda-Ribeiro, 1920, B. garbeanus Miranda-Ribeiro, 1920, and B. bufonoides Miranda-Ribeiro, 1920 (SVL = 12.4 mm, 17.6 mm, and 13.5 mm, respectively; Pombal Jr (2010)). …”

“…Based on this scenario, one could expect that Brachycephalus is likely to be found in montane regions of the Brazilian Atlantic Forest with similar climatic conditions, including the possibility of new species. Indeed, over the last decade, 16 new Brachycephalus species were described (Alves et al, 2009; Haddad et al, 2010; Pombal Jr & Izecksohn, 2011; Napoli et al, 2011; Clemente-Carvalho et al, 2012; Garey et al, 2012; Condez et al, 2014; Condez et al, 2016; Pie & Ribeiro, 2015; Ribeiro et al, 2015), suggesting that species diversity of the genus may still be underestimated.…”

Evolution of morphology and locomotor performance in anurans: relationships with microhabitat diversification

“…Only adult males were measured, and sex was identified by external morphological characters, such as presence of vocal sacs, inguinal spots, nuptial pads, spines on fingers, darkened throats and differences in colour generally present in males. In the absence of external characters, sex determination occurred through the presence of vocal slits in adult males (Pombal & Izecksohn, 2011).…”

Sapindaceae em um remanescente de Floresta Estacional Semidecidual no município de Engenheiro Paulo de Frontin, RJ, Brasil

“…Além disso, é interessante salientar que, apesar deste trabalho apresentar a mais detalhada descrição da flora de Sapindaceae de uma localidade do Centro-Sul Fluminense até o momento, dois anos antes da publicação de Allophylus exappendiculatus por nossa equipe (Somner et al 2013), uma nova espécie de anfíbio, Brachycephalus margaritatus (Brachycephalidae), também foi descrita para essa região (Pombal Jr. & Izecksohn 2011 Árvores, arbustos ou lianas; nas lianas um par de gavinhas na base da inflorescência, lactescentes ou não, caule cilíndrico, estriado, costado ou sulcado, nas lianas, em seção transversal, um único cilindro vascular, ou um cilindro vascular central e 3-10 cilindros vasculares periféricos, ou ainda lobado; estípulas presentes ou ausentes. Folhas alternas, compostas paripinadas ou imparipinadas, variando de trifolioladas, pinadas e tripinadas; estípulas presentes ou não, folíolos com margem denteadoserreada ou inteira, com ou sem domácias na face abaxial.…”
