The recent apple snails of Africa and Asia (Mollusca: Gastropoda: Ampullariidae: Afropomus, Forbesopomus, Lanistes, Pila, Saulea): a nomenclatural and type catalogue. The apple snails of the Americas: addenda and corrigenda.

Ampullariidae are freshwater snails predominantly distributed in humid tropical and sub-tropical habitats in Africa, South and Central America and Asia. This catalogue is concerned only with the non-fossil Old World species, the majority of which are placed in the genera Pila and Lanistes, with a few species in Afropomus, Forbesopomus and Saulea. Pila occurs in Africa and Asia, Lanistes, Afropomus and Saulea only in Africa and Forbesopomus only in Asia. New World taxa were catalogued in a previous publication. The taxonomy of the group is heavily based on shell morphology but the true number of valid taxa remains unknown, pending revisionary work. This catalogue provides the rigorous nomenclatural base for this future work by bringing together all the available and unavailable genus-group and species-group names that have been applied to Recent Asian and African ampullariids, indicating their current nomenclatural status (species, subspecies, synonyms, etc.). Fossil taxa are not included. The catalogue lists 21 published genus-group and 244 published species-group names of Old World ampullariids, excluding 25 names that are incertae sedis and cannot be definitively determined as Old or New World. Of these 265 Old World names, five genus-group and 104 species-group (including 30 infraspecific) names are currently valid. There are 16 genus-group synonyms, 118 species-group synonyms and four species-group homonyms that are not treated as junior synonyms. Also listed are five unavailable family-group, one unavailable genus-group and 18 unavailable species-group names, and a number of unpublished names from museum labels. The catalogue provides bibliographic details for all published names, locations of type material, details of type localities and geographic distributions as far as can be ascertained given the confused state of the taxonomy. The catalogue is a work of nomenclature; it is not a revisionary work of taxonomy. Additional details and corrections to the earlier catalogue of the apple snails of the Americas are provided. No new names are proposed. Seven apparently new combinations are introduced, all with the genus Pila Preston: complicata Reeve, dira Reeve, major Germain (described as a variety of ovata Olivier), major Germain (described as a variety of speciosa Philippi), obvia Mabille, pallens Philippi, turbinoides Reeve.
