New karyotype for Mesomys stimulax (Rodentia, Echimyidae) from the Brazilian Amazon: A case for species complex? [PDF]
Ecol Evol, 2021 We studied the karyotype of Mesomys stimulax collected from the Amazon rainforest. The obtained karyotype (2n = 60 and FN = 110) differs from that described in the literature. These results suggest that M. stimulax may represent a complex of species and/or cryptic species.
