The study of Nicaraguan land snails is fragmentary. Recent sampling produced specimens of an undetermined species of Pseudopeas Putzeys, 1899. This genus was segregated from Opeas Albers, 1850 by reason of its prominent rib sculpture and later re-de- scribed by Pilsbry (1906) for the characteristic spiral sculpture of its nepi- onic whorls. Baker (1927) named a new subgenus Dysopeas for species where the spiral sculpture covers the entire shell, not only the nepionic whorls. The Nicaragua specimens show nepionic and body sculptures that precisely match descriptions and illustrations given by Pilsbry and Baker for the complex Pseudopeas/Dysopeas. Since 1999, a total of 160 specimens have been collected from El Castillo on Río San Juan, Islet...
