Comparison of nominal species and molecular groups in Lanistes from the southern Malawi Basin. A) Lanistes sp. (ovum-like); B) L. solidus; C) L. nyassanus. One molecular group (group A) contains exclusively specimens of L. solidus and L. nyassanus, whereas the other (group B) consists predominantly of L. sp. (ovum-like) and L. solidus. Blue spheres indicate the number of specimens belonging to a certain nominal species and molecular group, whereas colored connections link specimens that come from the same locality but occupy different spheres, i.e. green for group A, orange for group B.
