“…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.…”

A new species of Brachycephalus (Anura: Brachycephalidae) is described from the Atlantic Forest of northeastern state of Santa Catarina, southern Brazil. Nine specimens (eight adults and a juvenile) were collected from the leaf litter of montane forests 790–835 m above sea level (a.s.l.). The new species is a member of the pernix group by its bufoniform shape and the absence of dermal co-ossification and is distinguished from all its congeners by a combination of its general coloration (dorsal region of head, dorsum, legs, arms, and flanks light, brownish green to dark, olive green, with darker region in the middle of the dorsum and a white line along the vertebral column in most specimens) and by its smooth dorsum. The geographical distribution of the new species is highly reduced (extent of occurrence estimated as 25.04 ha, or possibly 34.37 ha). In addition, its habitat has experienced some level of degradation, raising concerns about the future conservation of the species. Preliminary density estimates suggest one calling individual every 3–4 m2 at 815–835 m a.s.l. and every 100 m2 at 790 m a.s.l. Together with the recently described B. boticario and B. fuscolineatus, the new species is among the southernmost species of Brachycephalus known to date.

“…The species of this genus are found on the eastern coast of Brazil between the states of Bahia, in the northeast, and Santa Catarina, in the south (Frost 2017), with most occurring at altitudes of over 600 m in the Serra do Mar (Ribeiro et al 2005, Alves et al 2006. Many of these species have been described recently (Garey et al 2012b, Ribeiro et al 2015, 2017, Bornschein et al 2016a, which emphasizes the importance of surveys in the least well-known remnants of Atlantic Forest, which are often found in relatively inaccessible areas of high altitude. The biodiversity corridors of the Atlantic Forest -the Central Atlantic Forest corridor, the Serra do Mar corridor, and the Northeast corridor (Rocha et al 2003) -contain a considerable number of endemic vertebrates, including anuran amphibians, and the coast of Paraná is located within the largest continuous remnant of Atlantic Forest, which is part of the Serra do Mar corridor (Câmara 2005), which implies that the state may have more endemic anurans than currently known.…”

Anuran amphibians in state of Paraná, southern Brazil

2018

The state of Paraná, located in southern Brazil, was originally covered almost entirely by the Atlantic Forest biome, with some areas of Cerrado savanna. In the present day, little of this natural vegetation remains, mostly remnants of Atlantic Forest located in the coastal zone. While some data are available on the anurans of the state of Paraná, no complete list has yet been published, which may hamper the understanding of its potential anuran diversity and limit the development of adequate conservation measures. To rectify this situation, we elaborated a list of the anuran species that occur in state of Paraná, based on records obtained from published sources. We recorded a total of 137 anuran species, distributed in 13 families. Nineteen of these species are endemic to the state of Paraná and five are included in the red lists of the state of Paraná, Brazil and/or the IUCN. Two anuran species were categorized as Near Threatened by the IUCN and 27 species were listed as Data Deficient in one or more lists. According to IUCN 49.6% of the anuran species recorded had their population trends stable, 19% in declined, only 1.4% is increased and 20.4% had your population trends unknown. We also recorded the occurrence in Paraná of the exotic invader anuran Lithobates catesbeianus. We consider our list of species to be a relatively reliable estimate of the anuran diversity of the Brazilian state of Paraná, although new species records are expected, mainly because there are many regions that have not yet been sampled.

Anfíbios anuros do estado do Paraná, sul do BrasilResumo: O estado do Paraná, localizado no sul do Brasil, originalmente possuía praticamente toda sua área coberta pelo bioma Mata Atlântica com algumas porções do bioma Cerrado. Atualmente, pouco resta das formações destes biomas, sendo a maior parte remanescentes florestais de Mata Atlântica, localizados na região costeira do Estado. Apesar de haver estudos sobre anuros no estado do Paraná, até então nenhum deles proveu uma lista dos anuros com ocorrência no Estado, o que pode dificultar o conhecimento sobre a potencial diversidade de anuros e restringir medidas de conservação. A partir dessa lacuna, elaboramos uma lista das espécies de anuros com registro para o Paraná, a partir de dados de estudos publicados. Registramos um total de 137 espécies de anuros, pertencentes a 13 famílias. Dentre estas, 19 espécies de anuros são endêmicas do estado do Paraná e cinco encontram-se relacionadas sob algum grau de ameaça de extinção na lista vermelha do estado do Paraná, do Brasil e/ou da lista global da IUCN. Duas espécies de anuros foram categorizadas como Quase Ameaçada pela IUCN e 27 espécies foram listadas como Dados Insuficientes nestas listas. De acordo com a IUCN, 49,6% das espécies de anuros registradas apresentaram tendências populacionais estáveis, 19% diminuíram, apenas 1,4% aumentaram e 20,4% apresentaram tendências de sua populações desconhecidas.

“…In the last decade, intensified fieldwork has led to the description of 23 species (Frost 2018), but data on natural history lag behind the rate of new species descriptions.

“…The species is a micro-endemic frog that occupies an estimated 41 ha of montane forests in the Atlantic Forest (Bornschein et al 2016). The description of the advertisement call of the new species was based on the calls of 17 individuals (Garey et al 2012). Bornschein et al (2018) reported that the note length of B. tridactylus is greater than that of B. albolineatus.…”

Redescription of the advertisement call of Brachycephalus tridactylus (Anura: Brachycephalidae)

Redescription of the advertisement call of Brachycephalus tridactylus (Anura: Brachycephalidae). Miniaturized frogs of the genus Brachycephalus have restricted geographical distributions throughout the Atlantic Forest. Ecological data for most species are scarce and advertisement calls have been described for only 12 of the 36 known species, including B. tridactylus. The considerable duration of note length of the advertisement call of B. tridactylus has been mentioned in comparative studies of vocalizations in Brachycephalus. The single original recording of B. tridactylus, together with recordings made in March 2016 at the type locality, were analyzed to document any variation and redescribe the advertisement call of the species. In the recent recordings of B. tridactylus, the average length of the call is 50.8 s and the call is composed of 10–13 notes emitted at a note rate of 3.7–8.3 notes per min. The notes are isolated and composed of 1–3 pulses, with the note duration varying from 0.002–0.021 s. These values are not consistent with the original description of the call of B. tridactylus. The note duration is 89% shorter and the original description does not include notes with 1–3 pulses. The notes of B. tridactylus have few pulses, whereas those of B. ephippium have several. The advertisement call of B. tridactylus differs from that of B. albolineatus and B. mirissimus by having only isolated notes.
