Les Mollusques
du lac TanganyikaEric Genevelle (janvier 2000)
Le premier à avoir sérieusement travaillé sur les mollusques du lac est Leloup (les photos de l'article viennent de lui).

En 1987, une révision de ces mollusques eut lieu par D.S. Brown et G. Mandahl-Barth dans un fascicule nommé LIVING MOLLUSCQ OF LAKE TANGANYIKA: A REVISED AND ANNOTATED LIST.
Depuis, à ma connaissance, rien de plus n'a été publié dans le domaine. C'est donc cette liste qui fera référence dans notre article. Notez que les espèces suivies d'un Astérix * sont endémiques du lac Tanganyika, soit un total de 44 espèces et 2 sous espèces endémiques pour 75 espèces présentes dans le lac.

Un grand merci à Liliane Moeremans pour m'avoir fourni l'ensemble de ces photos et à Rudy Jocqué de la section Invertébrés du Muséum de Centre Afrique de Tervuren pour nous avoir donné accès à l'ensemble des collections.
