Oxymycterus hucucha
''Oxymycterus hucucha'', also known as the Quechuan Hocicudo,〔Musser and Carleton, 2005; Dunnum et al., 2008〕 is a species of rodent in the genus ''Oxymycterus'' of family Cricetidae from South America. It is found only in a small region of the Andes in central Bolivia, where it lives in cloud forest at altitudes from 2600 to 3000 m.〔Hinojosa et al., 1987, p. 15; Musser and Carleton, 2005〕
Exceptionally small for its genus,〔Hinojosa et al., 1987, p. 1〕 ''O. hucucha'' was first recognized as new when a specimen was caught in 1984 in the Siberia Cloud Forest in Bolivia's Cochabamba Department, near the border of Santa Cruz Department. It was recognized as an ''Oxymycterus'' by its long claws relative to other, sympatric small akodontine rodents.〔Hinojosa et al., 1987, p. 2〕 Two other specimens caught nearby〔Hinojosa et al., 1987, p. 15〕 in 1955 and 1979 were then recognized as pertaining to the same species; one had been misidentified as ''Akodon mimus''.〔 In 1987, ''O. hucucha'' and another small ''Oxymycterus'', ''O. hiska'' from Peru, were named and described in an ''American Museum Novitates'' paper by Flavio Hinojosa, Sydney Anderson, and James Patton.〔 ''O. hucucha''s specific name is derived from ''hucucha'', which means "mouse" in Quechua, the local Amerindian language in the region where the species is found.〔
It is similar in size to ''O. hiska'', but slightly smaller, and the fur of the upperparts is more pale and reddish. Furthermore, the skull is narrower, the palate is longer, and the upper incisors are oriented more to the front, among other differences. Its coloration resembles that of some young ''O. inca'', a larger ''Oxymycterus'' that occurs in the same region, but the latter have larger feet.〔
The IUCN lists its conservation status as "endangered" because it has a small distribution, its habitat is being destroyed, and it is not known from any protected areas.〔
