Genera of Euryphyminae View in CoL 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. 5 View 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. 3C View FIGURE 3 , 4B View FIGURE 4 , 7G View 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. 7I View 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. 3G View FIGURE 3 , 4E View FIGURE 4 , 7H View 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. 3B View FIGURE 3 , 4A View FIGURE 4 , 6F View FIGURE 6 )............................................................................................ Euryphymus
– Integument with a sandy brownish colour, posterior margin of pronotum with corrugated edges ( Figs. 3M View FIGURE 3 , 4M View FIGURE 4 , 6B View 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. 3I View FIGURE 3 , 4G View FIGURE 4 , 6E View FIGURE 6 )........ Platacanthoides
– Body small. Cerci slightly excurved, with obliquely truncate apex; angle between apex and base of cercus rounded rather than angular ( Figs. 3K View FIGURE 3 , 4L View FIGURE 4 , 7A View 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. 7E View FIGURE 7 )............................................................................................. Calliptamulus
– Male cerci with a narrowed base and wided but obliquely truncate apex ( Figs. 3F View FIGURE 3 , 4H View FIGURE 4 , 6A View 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. 3E View FIGURE 3 , 4D View FIGURE 4 , 7D View FIGURE 7 )............................ Brachyphymus
– Male cerci narrowed at base, apex strongly widened and rounded ( Figs. 3H View FIGURE 3 , 4F View FIGURE 4 , 6D View FIGURE 6 ). ……….............. Amblyphymus
14. Body robust; hind wings often brightly coloured. Cercus upcurved sharply, apex with complex 3-dimensional shape ( Figs.3J View FIGURE 3 , 4J View FIGURE 4 , 5C View FIGURE 5 ).................................................................................... Plegmapterus
– Body slender, cercus forms 45⁰ angle with base; apex knob-like rounded ( Figs. 3M View FIGURE 3 , 4K View FIGURE 4 , 7B View FIGURE 7 ).............. Plegmapteropsis
