Chondrina amphorula Shileyko, 1984 (pl. 13 figs B–C)

Notes.—According to Shileyko (1984: 231–233) this species resembles Chondrina arcadica caucasica ( Ehrmann, 1931) (pl. 13 fig. D) but is specifically distinct based on the following characteristics (after Shileyko 1984). At first glance C. amphorula appears to possess two palatal folds, while in C. a. caucasica three are evidently present. This is a clear distinction in localities where both species co-occur, i.e. no intermediates are found. Additionally, the penial loop is consistently longer and thinner in C. amphorula than in C. a. caucasica. The species is reported from the following localities: Russia, Kabardino-Balkaria, N-Caucasus, Habaz (44.05°N / 41.77°E), Riykol ravine (= 2 km W of Habaz), Coll. W.J.M. Maassen (leg. Kuznetsov), and from the northern Caucasus (Daghestan) and Armenia. Its affinities with the other species in the genus are unclear. It could either be closely related to the relatively recent radiation of C. arcadica (to which it shows some morphological resemblance) or belong to the older radiation which also includes C. tatrica .
