Llorenteana, a New Butterfly Genus from the American Continent (Lepidoptera: Nymphalidae: Satyrinae

The genus Llorenteana, gen. nov., is diagnosed and described to allocate the enigmatic, relictual, satyrine butterfly, Euptychia pellonia Godman, 1901. The taxonomy of this species had been superficial, variable and unstable for more than a century. The new genus is monobasic and endemic to the montane pine-oak forests of the Northern Mexican Altiplano. Its morphology suggests it should be placed within the Ypthimina Miller, 1968, a subtribe notably diverse in other continents, mainly Africa and Asia, but so far unreported in the American continent.
