Two new species of the American ricinulid genus Pseudocellus Platnick, 1980 are herein described from eastern Cuba: one from a cave in the mountains of northwestern Guantánamo Province and another from a coastal site in southeastern Santiago de Cuba Province. Both species are remarkable by their deep morphological distinction from all other Cuban described congeners, especially those from the same geographical region, e.g., the former possesses very well developed eyespots and the latter has a large retrolateral apophysis in male leg II tibia (also present but much smaller in females). As results, the Cuban ricinulid fauna is now known to comprise 12 nominal species (all congeneric and endemic to the main island), with eight of them (67%) restricted to its eastern region.
