The Santa Rosa shrew pouch rat ( Monodelphis sanctaerosae ) is only known from a single specimen that was used as the holotype for the first description published in 2012. It was caught near Santa Rosa de Roca in Bolivia's Santa Cruz Department .

description

The holotype, a female, has a head body length of 10.8 cm, a 6 cm long tail and a weight of 23 g. Outwardly, the species with its predominantly brown-gray coloration resembles the domestic shrew pouch rat ( Monodelphis domestica ). The sides of the head are light reddish, the belly is light beige. The tail is hairy only on the first centimeter at the base, the hairless part is dark on the top and light colored on the underside. Like probably all shrew pouch rats, the females do not have a pouch. The number of teats is unknown as they were not visible on the holotype. The karyotype of the Sancta pink shrew pouch rat is unknown. The Santa Rosa shrew pouch-rat can be distinguished from the house-shrew-pouch-rat by its smaller size and the reddish head sides (gray with the house-shrew-pouch-rat).

Way of life

The holotype of the Santa Rosa shrew pouch rat was caught on the edge of a seasonally flooded grassland in a savannah landscape ( Chiquitania ) resembling the Brazilian cerrado with scattered individual trees and small dry forests with a closed canopy. Whether this is the typical habitat of the species is uncertain, as only one specimen is known. It is also not yet possible to clarify whether the species is endemic to a small area around the site or whether it is more widespread and other specimens of the species have so far been confused with the house shrew rat. So far nothing is known about the behavior, diet, activity patterns and reproduction of the animals.

status

The Santa Rosa shrew pouch rat is not listed by the IUCN . Since only a single specimen has been caught so far, no statement can yet be made about a possible hazard.
