Remark.

I could not find the original description of this species in Preston’s works devoted to new taxa of African land and freshwater mollusks (Preston 1910a, b, 1911, 1912, 1913). Preston introduced several tens of species names, including those with the species epithet " elgonensis " (for instance, Ledoulxia elgonensis Preston, 1914, family Urocyclidae Simroth, 1899), however among lymnaeid taxa described by him the species name Lymnaea (or Limnaea) elgonensis is absent. Both Hubendick (1951) and Brown (1994), in their comprehensive works dealing with the African Lymnaeidae, do not mention such a species. I am not sure Preston ever described it formally.
