The land snail fauna of several South American countries is very incompletely known despite quite extensive literature. For Bolivia there is only an incomplete and outdated list from 1953, Peru is covered by a name list only (2003), and Ecuador has a catalogue for the mainland Orthalicoidea only (2008). Other countries (Brazil, Chile, Argentina) are covered by recent works from local malacologists, and for some others (Colombia, French Guiana) recently overviews have been published, of which especially the one for French Guiana is also very useful for neighbouring countries like Suriname.
This new paper partly aims to fill that gap for Bolivia, Ecuador and Peru treating the minor families of the Orthalicoidea. Covering the three countries this synopsis summarizes all known species and part of their localities (from literature and some major EU museums). Also one new species is described.
