New morphological data on the rare sigmodontine Mindomys hammondi (Rodentia, Cricetidae), an arboreal oryzomyine from north-western Andean montane forests

The monotypic rodent Mindomys Weksler, Percequillo & Voss, 2006 (Cricetidae, Sigmodontinae) is one of the rarest members of the speciose tribe Oryzomyini. As this species is restricted to the Chocó forests of the western Andean slope in northern Ecuador, our knowledge is...
