Genera of Euryphyminae  can now be identified using this key to the males:

An updated key to the Southern African genera of Euryphyminae Modified  from Dirsh (1956)

1. Pronotum in prozona crest-like with deep incision at first transverse sulcus ( Fig. 5View FIGURE 5)....................... Pachyphymus 

– Pronotum without “camel-like” humped crests.............................................................. 2

2. Male cerci straight.................................................................................... 3

– Male cerci excurved................................................................................... 5

3. Lower margin of male cercus strongly dented, cerci straight, ending in an acute point ( Figs. 3CView FIGURE 3, 4BView FIGURE 4, 7GView FIGURE 7).... Aneuryphymus 

– Male cercus longer, ending in rounded or flattened surface..................................................... 4

4. Wings shortened, male cercus long and slender, strongly excurved and rounded with the angle between apex and base of cercus obstuse ( Fig. 7IView FIGURE 7).............................................................................. Phymeurus 

– Male cercus stump-like, not quite straight along bottom margin, apex square-like, does not form right angle with bottom margin ( Figs. 3GView FIGURE 3, 4EView FIGURE 4, 7HView FIGURE 7)........................................................................... Rhodesiana 

5. Male cercus relatively short, with very wide triangular base covered in coarse sensilla or setae, ending in simple pointed or blunt apex................................................................................................ 6

– Male cercus relatively longer, often upcurved with or without complex 3-dimensional shape.......................... 7

6. Male cerci short and slightly excurved, as long as its width, posterior margin of pronotum acute angular ( Figs. 3BView FIGURE 3, 4AView FIGURE 4, 6FView FIGURE 6)............................................................................................ Euryphymus 

– Integument with a sandy brownish colour, posterior margin of pronotum with corrugated edges ( Figs. 3MView FIGURE 3, 4MView FIGURE 4, 6BView FIGURE 6).............................................................................................. Plegmapteroides 

7. Male cercus apex folded into almost right angle relative to base. Apex pointed or blunt. Sclerotized lobe extends outwards at right angle juncture.................................................................................... 8

– Male cercus upcurved at various angles with apex from pointed to blunt or rectangular or triangular.................... 9

8. Male cercus slender towards apex, ending in blunt point; basal lobe at right angle ( Figs. 3IView FIGURE 3, 4GView FIGURE 4, 6EView FIGURE 6)........ Platacanthoides 

– Body small. Cerci slightly excurved, with obliquely truncate apex; angle between apex and base of cercus rounded rather than angular ( Figs. 3KView FIGURE 3, 4LView FIGURE 4, 7AView FIGURE 7)................................................................. Calliptamuloides 

10. Body smooth, dorsum of pronotum flat when viewed laterally, posterior margin of pronotum obtuse................... 11

– Upcurved cercus, body varies in rugosity but not very smooth; dorsum of pronotum may be tectiform, rounded or irrelgular but does not appear flat when viewed laterally................................................................ 12

11. Body small. Fastigium of vertex concave, lower margin of male cerci slightly dented, male cerci hook shaped ( Fig. 7EView FIGURE 7)............................................................................................. Calliptamulus 

– Male cerci with a narrowed base and wided but obliquely truncate apex ( Figs. 3FView FIGURE 3, 4HView FIGURE 4, 6AView FIGURE 6) …................. Calliptamicus 

12. Integument marked with patterns of brown, reddish-brown and grey; abdomen may be yellow; integument appears smooth and rather shiny......................................................................................... 13

– Greyish brown integument moderately rugose and matte coloured, not smooth and shiny............................ 14

13. Male cerci hook-shaped and prosternal process “pointy” ( Figs. 3EView FIGURE 3, 4DView FIGURE 4, 7DView FIGURE 7)............................ Brachyphymus 

– Male cerci narrowed at base, apex strongly widened and rounded ( Figs. 3HView FIGURE 3, 4FView FIGURE 4, 6DView FIGURE 6). ……….............. Amblyphymus 

14. Body robust; hind wings often brightly coloured. Cercus upcurved sharply, apex with complex 3-dimensional shape ( Figs.3JView FIGURE 3, 4JView FIGURE 4, 5CView FIGURE 5).................................................................................... Plegmapterus 

– Body slender, cercus forms 45⁰ angle with base; apex knob-like rounded ( Figs. 3MView FIGURE 3, 4KView FIGURE 4, 7BView FIGURE 7).............. Plegmapteropsis
