Species of rodent

Species of rodent

[Nephelomys] pirrensis: Weksler, Percequillo, and Voss, 2006}} Nephelomys pirrensis, also known as the Mount Pirre rice rat, is a species of rodent in the genus Nephelomys of family Cricetidae. Its type locality is at Mount Pirri or Pirre in eastern Panama, at an altitude of 4500 ft, and it has also been recorded on Mount Tacarcuna.

N. pirrensis is a relatively large species. The color of the upperparts is brown and becomes lighter towards the sides. The throat is gray and the other parts of the underparts are buffy. The nose, ears, and forefeet are blackish and the thinly haired hindfeet are dark brown. The tail is dark brown above and a little paler below. Juveniles have darker fur. It is similar in size to N. devius, which occurs further west in Costa Rica, but is somewhat darker and has smaller auditory bullae. In six specimens, the total length ranges from 309 to, the length of the tail vertebrae from 159 to, and the hindfoot length from 34 to.

It lives in holes under rocks and logs along streams. Several specimens were caught in animal runways.

It was first described, in 1913, as a species of Oryzomys, Oryzomys pirrensis, When that species was transferred to the new genus Nephelomys in 2006, N. nimbosus was recognized as a separate species.
