Remarks and comparative notes

Numerous specimens from the Ditsong National Museum of Natural History (Pretoria), were, at first sight, considered to belong to one, or even several, new species. Examination of the aedeagi revealed, however, no differences sufficient for a separation of these forms from P. laetulus   ( Fig. 7 View Fig E–G). Unless reliable diagnostic differences dictate otherwise, it is considered appropriate to treat P. laetulus   as a species that shows significant variability. Fig. 7A–D View Fig shows the pronota of specimens from different locations to illustrate individual variations.

One of the Malvern specimens (KwaZulu Natal Province of South Africa) collected by Marshall in 1897 (BMNH) bears a type label by A. Grouvelle, with the name ‘ Psammoecus distinctus   ’. Since no description of a taxon with that name is available, the name is to be considered a manuscript name.
