Brucepattersonius

Brucepattersonius is a living in South America rodent genus of the group of the New world. It includes seven species.

The animals of this genus are small, mouse -like animals that are characterized by their elongated snout and so outwardly resemble the grave mice. They inhabit the south-eastern Brazil and the extreme northeast Argentina ( Misiones Province), their habitat is hilly forests where they reside mainly in the higher regions. They are bottom dwellers, otherwise little is known about their way of life.

The following seven types can be distinguished:

• Brucepattersonius griserufescens from the south-eastern Brazil,
• Brucepattersonius guarani from Northeast Argentina,
• Brucepattersonius igniventris from southeastern Brazil,
• Brucepattersonius iheringi from southeastern Brazil and northeastern Argentina,
• Brucepattersonius misionensis from Northeast Argentina,
• Brucepattersonius paradisus from Northeast Argentina and
• Brucepattersonius soricinus from southeastern Brazil.

The genus was first described on the basis of four new species from Brazil (B. albinasus, B. griserufescens, B. and B. igniventris soricinus ) in 1998. He also added the already longer known species B. iheringi the genus. This species was taxonomically controversial in the past, most recently at the grave mice ( Oxymycterus ) classified. 2000, three other species described (B. guarani, B. and B. misionensis paradisus ) derived from Northeast Argentina and are all known only by a single specimen. 2006, led by Hershkovitz as separate species B. albinasus and B. were griserufescens recognized as a sort. It is conceivable that in the future more populations are combined to form common kinds as more is known about the animals.
