Peru reports a very high diversity of mammals; however no Peruvian department or region has an updated list of mammals to date. Therefore, we present an updated list for Ucayali, which includes 192 species, belonging to 11 orders and 35 families (comprising 38% of all Peruvian mammals). Of these, 56 are recorded in protected areas and 189 species in unprotected areas, respectively. Three endemic species for the country were found in Ucayali: Sciurus pyrrhinus, a squirrel, Neusticomys peruviensis a cricetid mouse, and Makalata rhipidura an echimyd rodent. 86 different locations had specimen records (mostly located along rivers). Two areas with scarce or lack of records were found and rated as "Information gaps": 1) northeast of Ucayali (part of the Sierra del Divisor National Reserve), and 2) eastern Ucayali, composed of the territory crossed by the Yucanya River, the Yurua River, and downstream Purus River (part of the Alto Purus National Park). These areas are recommended for biodiversity and conservation studies.
