oa Annals of the Natal Museum - On certain morphological features of Bulinus africanus and B. Globosus (Mollusca: Pulmonata) and the distribution of these species in south east Africa

Volume 18, Issue 2
  • ISSN : 0304-0798



Examination of samples of Bulinus (Physopsis) africanus (Krauss) and B. (P.) globosus (Morelet) collected near their type localities confirmed the diagnostic value of characters of the copulatory organ. Parasitism by larval trematodes reduced the size of the copulatory organ in B. (P.) globosus. B. (P.) africanus was found to occur further south than B. (P.) globosus in Natal, South Africa.
