Type material.

I could not recognize the syntype(s) of this variety in ZMB collection. However, there are several specimens (subadult shells) labelled as Limnaea lagotis var. costulata and collected in Charik-Kul’ Lake (Uzbekistan, in vicinities of Katta-Kurgan Town) by Fedchenko (see Fig. 11). Martens (1874: 27) discussed shells from this locality in his monograph under the name Limnaea lagotis but did not assign them to a certain variety of this species. It is unclear who and when identified shells from Charik-Kul’ as Limnaea lagotis var. costulata .

Type locality.

Uzbekistan, Tashkent City, leg. A.P. Fedchenko.

Current taxonomic allocation.

Radix (Peregriana) lagotis (Schrank, 1803) or Radix (Radix) sp.

Remark.

In 1897, von Martens (1897a) described a new variety Limnaea javanica var. costulata from Indonesia (Java Island). I was not able to find the type series of it in ZMB collection.
