Three populations of S. sparsipunctata from the eastern coast of Lake
Tanganyika were studied by light and electron microscopy. We found no
distinct differences between the type variety and var. laevis; therefo
re we propose to include the var. laevis with the typical variety. An
amended description of S. sparsipunctata based on LM and SEM observati
ons is given.
