The rediscovery of Rhagomys rufescens (Thomas, 1886), with a morphological redescription and comments on its systematic relationships based on morphological and molecular (cytochrome b) characters

The presence of Wilfredomys oenax (Rodentia: Cricetidae: Sigmodontinae) in São Paulo state, southeastern Brazil: a locally extinct species?

“…2); light orangish manus and feet; long dorsoventrally bicolored tail; medium sized rodent (Table 1), much larger than Juliomys, the most externally similar Atlantic Forest species (Pavan & Leite, 2011: Table I and II). Additionaly, craniodental characters described by Percequillo et al (2004) unambiguously distinguish Wilfredomys from other pentalophodont Atlantic Forest Sigmondontinae genera: Skull with medium length rostrum and shallow and narrow zygomatic notch ( Fig. 3A and B); narrow and hourglass-shaped interorbital region, with squared margins and a shallow depression along the frontals (Fig.…”

“…Conversely, Wilfredomys Ávila-Pires (1960) and Pine (1980). The exception are a few specimens of W. oenax cited when comparing it to Juliomys (González, 2000;Oliveira & Bonvicino, 2002;Pardiñas & Teta, 2011) and Rhagomys Thomas, 1917(Percequillo et al, 2004) -without pointing localities to each W. oenax specimen -and in two unpublished thesis, Pacheco (2003) and Queirolo (2009), both mentioning specimens exclusively from Uruguay and Rio Grande do Sul, Brazil.…”

“…The most updated of those lists was made by Vivo et al (2011), which reported 231 species and described recent advances on mammal studies from which some facts draw attention to São Paulo state mammal fauna, such as the presence of recently described species (Leite et al, 2008;Percequillo et al, 2011;Costa et al, 2011) and even a new genus . New data on mammal species from São Paulo are obtained through new inventories (e.g., Gregorin et al, 2004;Steiner-Souza et al, 2008;Velazco, et al, 2010) and by museum specimens (e.g., Silva et al, 2003;Gregorin et al, 2004;Pavan & Leite, 2011;Garbino, 2011), including records of rare and/or threatened species (e.g., Vaz, 2000;Percequillo et al, 2004;Vivo et al, 2011).…”

Bats (Mammalia: Chiroptera) of Mata do Paraíso research station, Viçosa, Minas Gerais, Brazil

“…), where is located the Estação de Pesquisa, Treinamento e Educação Ambiental (EPTEA) Mata do Paraíso (194 ha) (Ribon 2005). Inventories of non-volant small mammals (Rodentia and Marsupialia) have been conducted in EPTEA (Paglia et al 1995;Lessa et al 1999;Gonçalves and Oliveira 2004;Percequillo et al 2004), but no inventories of bats for the area have been published to date. This is the first survey of the bat fauna of the EPTEA Mata do Paraíso, conducted to filling in one of the gaps of knowledge of bat species distribution within Minas Gerais.…”

New distribution reports of Rhagomys rufescens (Rodentia: Sigmodontinae) Thomas, 1886

“…This is the first record of this species in the Espinhaço mountain range, and the fourth and northernmost report for the species in the state of Minas Gerais. It is located about 85 km northeast of the last registered location in the Estação de Pesquisa, Treinamento e Educação Ambiental Mata do Paraíso (EPTEA Mata do Paraíso), in the municipality of Viçosa (Percequillo et al 2004). The other known report for Minas Gerais is in the municipality of Poços de Caldas (Percequillo et al 2004) and Parque Estadual Serra do Papagaio, municipality of Baependi (Passamani et al 2011).…”
