Distribution, habitat and stock

The distribution area of Tyloyms bullaris located in Chiapas, Mexico, where the species only one specimen from Tuxtla Gutiérrez is known. In this field it is bound to tropical deciduous forests.

The World Conservation Union IUCN classified Tylomys a bullaris 2008 as threatened with extinction. This was justified by the limited availability and the likelihood of a strong stock decline, caused by the expected complete disappearance of the original habitat due to urbanization and conversion to agricultural area. 1996, the species was also classified as threatened with extinction. In Mexico it is legally performed as endangered ( NOM 059_ECOL -2001).
