Abstract

We report from three localities four new records of the threatened Brazilian Atlantic Forest endemic Chaetomys subspinosus (Olfers, 1818). These are the first records of this porcupine species from the state of Minas Gerais, and these new data extend the distribution of this species by approximately 220 km to the southwest. As C. subspinosus was observed in areas of transitional vegetation, this species may be found in a much broader spectrum of habitat types than previously thought. We recommend further surveys focusing on documenting this species.

Summary

Introduction

Chaetomys subspinosus (Olfers, 1818), Bristle-spined of 1,600 g This soli- Voss et al 2013). Chaetomys subspinosus was recorded recently in the eastern portion of the Caparaó National Park in the state of Espírito Santo at border with Minas Gerais state (Kaizer et al 2021), which represents the westernmost locality recorded to date. From the state of Minas Gerais, there is only indirect evidence of the occurrence of C. subspinosus, based on interviews with local residents (Oliver and Santos 1991; Giné and Faria 2018). From the state of Minas Gerais, there is only indirect evidence of the occurrence of C. subspinosus, based on interviews with local residents (Oliver and Santos 1991; Giné and Faria 2018). Giné and Faria (2018) provided the most recent review of the geographic distribution of C. subspinosus (117 georeferenced localities of occurrences), including field data, published records, and specimens in scientific collections, in addition to the modeling of the potential distribution of the species
