Systematics of the Enigmatic Neotropical Rodent Genus Microakodontomys (Cricetidae: Sigmodontinae): New Evidence Supporting Its Distinctiveness and Endangered Status

Zoologica Scripta, Volume 54, Issue 5, Page 587-600, September 2025.
ABSTRACT The diversification of Neotropical sigmodontine rodents represents one of the most remarkable evolutionary events among mammals, encompassing numerous endemic, rare, and endangered genera and species. One of the most emblematic examples is Microakodontomys transitorius Hershkovitz 1993, originally described from a single specimen based on ...

Chromosomal evolution of tribe Oryzomyini (Rodentia: Cricetidae: Sigmodontinae)

Mammalian Biology, 2022
Oryzomyini is the most diverse tribe of subfamily Sigmodontinae, comprising 30 genera and 147 extant species. Cytogenetic studies on Oryzomyini reflect this diversity, revealing an exceptional range of karyotype variability, with chromosome numbers ranging from 2n = 16 to 2n = 88.
