An annotated checklist and bibliography of the land and freshwater snails of México and Central America

Abstract

The checklist of the non-marine gastropod fauna summarizes the known species and subspecies that are recognized from México and Central America. It is an annotated list of 1800 terminal taxa presented in a hierarchical framework. These include 1502 native species plus 278 native subspecies, and 20 introduced species. The native species include 175 aquatic operculates, 84 aquatic pulmonates, 130 terrestrial operculates, and 1112 terrestrial pulmonates. In most cases in order to be as objective as possible the list uncritically records the most recent assignment of terminal taxa. In a few instances some changes are deemed necessary. For higher-level changes competing schemes are treated equally. In cases of terminals and higher taxa, readers are directed to the systematic works that discuss relevant taxonomy. It is anticipated that the annotated list will be a useful resource for everyone interested in non-marine gastropods and their nomenclature. In addition to clarifying some issues or points of confusion, this list should also provide an impetus for future work aimed at clarifying and resolving areas of taxonomic disagreement and/or uncertainty, and to make better known the non-marine molluscan fauna of México and Central America.
