Abstract

The Neotropical landsnails family Proserpinidae comprises the Caribbean genus Proserpina. The Cuban endemic species Proserpina (Despoenella) depressa and P. (D.) globulosa exhibit unique morphological and ecological features still poorly known. We made observations related to morphology and shell coloration, foot and mantle and its variations concerning some extant Cuban and Caribbean populations. Some ecological comments include their defense morphological traits and behavior like foot spasmodic movements. Likewise, we discuss the Cuban species disjunctive distribution. These mollusks inhabit moist karstic areas permanently threatened due to climatic change, forest loss and habitat fragmentation.
