Parasthetops Perkins & Balfour­Browne, 1994  

Parasthetops Perkins & Balfour­Browne, 1994: 37   (type species Parasthetops nigritus Perkins & Balfour­Browne, 1994   ).

The genus Parasthetops   comprises 21 species, including 13 new species described below. The genus has a wide distribution in South Africa and Namibia ( Fig. 88 View FIGURES 88–89 ), and there is one known locality in Zimbabwe. The majority of species and specimens have been collected from stones in the current of streams or rivers. New distribution records for four of the eight previously described species of Parasthetops   are given below. New locality records are not yet available for the following species ( Perkins & Balfour­Browne, 1994; map figures in parentheses): P. andreaei   ( Fig. 93 View FIGURES 93–94 ), P. camurus   ( Fig. 100 View FIGURES 97–100 ), P. reflexus   ( Fig. 94 View FIGURES 93–94 ), and P. rufulus   ( Fig. 94 View FIGURES 93–94 ).

The division of Parasthetops species   into groups is herein based primarily on dorsal sculpture and general body form. In most groups the form of the male genitalia corroborate the placement of species. In other cases, however, there is considerable difference in aedeagal form within a species group. For example, the aedeagi of the three species in the camurus   group ( Figs. 33–35 View FIGURES 32–35 ) are quite dissimilar from one another; however, none of the three show any obvious similarity to the aedeagi of species in other groups. Additional study is needed to confirm the composition of some of the species groups. Perhaps additional groups will become evident when more new species are discovered.
