Discussion No less than four species of Megerlina have been recorded from the same area off the eastern Cape coast from which the present specimens were recovered. Previous descriptions of these species, M. pisum (Lamarck), M. natalensis (Krauss), M. capensis (Adams & Reeve) and M. striata Jackson, have been based on very few specimens and it is unlikely that the full extent of the variation within the genus has been properly assessed, with the result that the relationships between these four species are unknown. The earlier descriptions distinguish between species on characters such as colour, strength of ribbing, depth of sulcus and size and shape of the punctae. The Meiring Naude specimens are all whitish in colour but pink or red around the.
