Description of the genital organs

( Fig. 3 , shell size of dissected animal: 10.6 × 3.7 mm). Penis without penial appendix, subdivided in a distal and proximal section; proximal section containing a centrally perforated verge; epiphallus very long, reaching ca. 5 × the length of penis, with a small caecum at its central part, a short flagellum present; penial retractor muscle attaching at the border of penis and epiphallus; vagina as long as penis, pedunculus with a long diverticulum largely surmounting the bursa copulatrix in length.

Remarks.

The principal morphological structure of the genital organs does not differ from the holotype of Meijeriella canaliculata (cf. Bank 1985) from the Island of Lesvos nor from that from the southern slope of the Kaz Dağı ( Fig. 2 ). For this reason, the species Bulimus frivaldskyi is here confined to the genus Meijeriella and removed from the genus Ena , as already suspected by other authors ( Bank 1985: 42, Hausdorf 2001). The shell of Meijeriella frivaldskyi differs from Meijeriella canaliculata by its rounded and not canaliculated last whorl; additionally, the majority of specimens of Meijeriella frivaldskyi differ by presence of a palatal swelling of the labium, which is said to miss in the Lesvian specimens of Meijeriella canaliculata (and which is also true for the Kaz Dağı population).
