【 摘 要 】

Enantiomorphism in gastropods is related to the shell shape: high-spired snails present a higher proportion of enantiomorphs, in the low-spired snails it is less frequent. This could be a consequence of the way the snails mate; shell mounting mating occurs in the high-spired species and is independent of the chirality while the low-spired snails mate face-to-face which implies a certain degree of genitalia adjustment for successful copulation. Cases of sinistral Pyramidula have been reported in Eurasia, however, it is the first time it has been observed in P. jaenensis and Spain.
