Abstract

In the course of a trip to Ecuador I had the opportunity of collecting topotypic specimens of the following nominal species of pulmonate molluscs: Biomphalaria cousini check for this species in other resources Paraense, 1966; Planorbis equatorius Cousin, 1887; P. canonicus Cousin, 1887; Lymnaea cousini check for this species in other resources Jousseaume, 1887 and P. boetzkesi Miller, 1879. Additional findings were: Helisoma trivolvis check for this species in other resources (Say, 1817), Biomphalaria peregrina check for this species in other resources (Orbigny 1835), Drepanotrema anatinum check for this species in other resources (Orbigny, 1835), D. kermatoides (Orbigny, 1835), D. lucidum (Pfeiffer, 1839), D. surinamense (Clessin, 1884), Lymnaea columella check for this species in other resources Say, 1817 and Physa acuta Draparnaud, 1805.

P. boetzkesi and P. canonicus are considered junior synonyms of Gyraulus hindsianus check for this species in other resources (Dunker, 1848) and Biomphalaria peregrina (Orbigny, 1835), respectively.
