Abstract

Scolodontidae are a Neotropical family of non-obligatory carnivorous snails with a complex taxonomy. Recent efforts to revise the genera within the family have gone a long way into restricting wastebasket taxa such as the genus Happia, which currently includes four species. Such revisionary work also facilitates the recognition and description of new taxa. In the present study, we include a further two species in Happia: one new, Happia acreana sp. nov., from Acre state, Brazil; and another transferred from the marine family Tornidae, previously classified as Cochliolepis surinamensis van Regteren Altena, 1966 and presently re-classified as ?Happia surinamensis (van Regteren Altena, 1966) comb. nov. The new data also extends the genus’s distribution to the Brazilian Amazon and highlights incorrect systematic assignments of a species described decades ago as a marine animal.
