Current taxonomic allocation.

Uncertain. Hubendick (1951) treated it as a species of unclear identity (possibly no lymnaeid). In my opinion, Limnaea nitidella is similar to another lymnaeid species described from Ecuador, Lymnaea cousini (Jousseaume, 1887) [see conchological characterization of this species in Paraense 1995; Pointier et al. 2004] and may represent its senior objective synonym.
