A new genus and species of pseudosigmurethrous orthurethran pulmonate of the family Cerastidae, Darwininitium shiwalikianum gen. n. and sp. n. is described from the Lesser Himalaya of Nepal. It represents the first record of an orthurethran with a fully developed pseudosigmurethrous pallial system,a completely closed secondary ureteric system. Biogeographically this new taxon provides a significant range extension for the family north of the previously known distribution range.
