Key to Afrotropical species of Perasis

Oldroyd (1970) mentioned the very close resemblance between carpenteri and transvaalensis , listing only two characters useful for their separation. Apart from the obvious differences in male genitalia (not studied by Oldroyd) I can find no other diagnostic features useful for keying these species. While arabicus and maura , both palaearctic species, have erroneously been listed as Afrotropical, both are readily separated from truly Afrotropical species by their possession of well-developed scutellar macrosetae.

1. Thoracic pleura uniformly micropruinose; silver pruinescence of hind margins of abdominal terga 2–5 continuous (broad laterally, narrow medially); ♂ genitalia as Figs 4–8 View FIGURES 4–8 ; East African species .................... ....................................................................................................................................... carpenteri Oldroyd

- Thoracic pleura not uniformly micropruinose, anepisternum and katepisternum with shiny apruinose areas anteriorly; silver pruinescence of hind margins of abdominal terga 2–5 confined to lateral parts, these areas not joining medially; ♂ genitalia as Figs 9–12 View FIGURES 9–12 ; Southern African species ..... transvaalensis Ricardo
