recently remarked on the study of this group: "It seems reasonable to assume that it is a speciose subfamily, but the delimitation of many alleged species, nearly all of which are based on shell characters only, remains unclear. The number of anatomical, not to mention molecular data, stands in violent contrast with the number of nominal species. Apart from that, many nominal species are only known from their

species are insufficiently known. The situation is complicated even more by the variability of the male part of the genital tract and the uniformity of the female part. In several cases, dissection is hampered by the size of the snails and even more so by the fragility of the uterus of these ovoviviparous animals. Also, they start reproducing before maximum size is reached. Therefore there is reason to be cautious with regard to taxa distinguished by size alone."
