Extension of the known geographic distribution of Diplomys labilis (Mammalia: Rodentia: Echimyidae): first record for Costa Rica

Abstract

Abstract:The Rufous Tree Rat, Diplomys labilis, is known to range geographically from Central Panamá to Colombia and probably Ecuador. It occurs in a variety of habitat types where it moves by the branches in the high canopy at night. We report the Rufous Tree Rat for Costa Rica, ranging outside its geographical distribution about 490 km west from its type locality.

Notes on the geographic range and distribution of two free-tailed bat species (Chiroptera, Molossidae) in Costa Rica

“…Finally, based on the mammal list published by Rodríguez-Herrera et al (2014) and other recent publications related to this topic (Ramírez-Fernández et al 2015, Villalobos-Chaves et al 2016, Woodman and Timm 2016, our results increase the total number of living mammals of Costa Rica to 253 species and to 115 the total number of bats species. These discoveries also show that despite that the order Chiroptera is considered a well-studied mammal group in the country, the most basic aspects of species biology such as geographic distribution and natural history are still unknown for many species of small mammals, mainly bats and rodents.…”

Extension of the known geographic distribution of Greenhall’s Dog-faced Bat, Cynomops greenhalli Goodwin, 1958 (Chiroptera, Molossidae): first records in Costa Rica

“…According to this report and recent confirmations of other mammals in Costa Rica (Rodríguez-Herrera et al 2014;Ramírez-Fernández et al 2015, 2020Villalobos-Chaves et al 2016Woodman and Timm 2017;González-Maya et al 2017;Sáenz-Bolaños et al 2019;York et al 2019), the number of extant mammal species for the country is increased to 261 species, including 121 total species of bat. A future goal should be to generate and analyze acoustic recordings in the country to better understand the distribution and ecology of C. greenhalli and other cryptic bat species.…”

Updated list of the mammals of Costa Rica, with notes on recent taxonomic changes

“…This is another southern species previously known as being distributed from Colombia to central Panama (Ramírez-Fernández et al 2015). These authors reported finding D. labilis in the Osa region of southwestern Costa Rica, about 490 km from its type locality (Ramírez-Fernández et al 2015). In addition, one animal of this species recently was observed and another collected in southern Nicaragua near the Costa Rica border (Martínez-Fonseca et al 2018).…”

“…Rodentia: Echimyidae: Diplomys labilis (Bangs, 1901). This is another southern species previously known as being distributed from Colombia to central Panama (Ramírez-Fernández et al 2015).
