ClassificationIdentification keys


1 Male: known only for G. varianum (A) and G. phagocossorum (B) 2

- Female (a, b) 3
 


2 Metasoma yellowish-orange with tergite 1 dark reddish-brown (A); hind femur and tibia yellowish-orange (A); antennal scrobe extends to eye margins (B) Genaemirum varianum (Tosquinet)

- Metasoma uniformly dark reddish-brown (a); hind femur and tibia dark reddish-brown (a); antennal scrobe less extensive, ending an ocellar diameter from eye margins (b) Genaemirum phagocossorum Rousse, Broad & van Noort

 


3 Frons with pronounced, horn-like projections pointed upward (A, B) 4

- Frons with a bisinuate transverse lamella (a), that may have minor projections (b) 7
 


4 Lower gena produced into a long spade-like protrusion (A, B); clypeus exceptionally expanded (A, B) 5

- Lower gena not expanded (a), or distinctly less expanded into a backward curved collar (b) ...6
 


5 Clypeus apically slightly convex, gena moderately protruded (A); metasoma brownish-black (B)  Genaemirum doryalidis Heinrich

- Clypeus apically deeply emarginate, gena dramatically protruded (a); metasoma yellowish-orange (b)  Genaemirum phacochoerus Broad, Rousse & van Noort
 


6 General coloration black (A); lower gena expanded into a backward curved collar (B) Genaemirum mesoleucum Heinrich

- General coloration dark red (a); lower gena not expanded (b) Genaemirum vulcanicola Heinrich
 


7 Frons with a forked, horn-like projecting carina above the antennal scrobes (A); second tergite medially punctate (B) ...8


- Frons with a broad to acute cordate lamella above the antennal scrobes (a); second tergite medially longitudinally strigose (metasoma lacking in ♀ allotype of Genaemirum varianum, but ♂ holotype tergite is longitudinally strigose) (b) 9
 


8 Apical margin of clypeus evenly rounded (A); tergite 1 puncto-striate laterally (B); ventral part of occipital carina slightly sinuate and not directed inward in lateral view (C); head and mesosoma bright red interspersed with numerous large yellow markings (A, C); metasoma and legs yellowish-orange with hind coxae largely white Genaemirum rhinoceros Heinrich

 

- Apical margin of clypeus slightly truncate in the middle (a); tergite 1 punctate laterally (b); ventral part of occipital carina strongly sinuate and directed inward in lateral view (c); head and mesosoma black interspersed with numerous large reddish-brown markings (a, c); metasoma and legs reddish-brown with hind coxa largely black ...Genaemirum filipazzii Dal Pos & Rousse
 


9 Metasoma, hind femora and tibiae yellowish-orange (A); frons with a broad cordate lamella above the antennal scrobes (B) ...10

- Metasoma, hind femora and tibiae reddish (a); frons with an acute cordate lamella above the antennal scrobes (b) Genaemirum phagocossorum Rousse, Broad & van Noort

 


10 Lower gena expanded into a backward curved, bluntly triangular, protuberance (A); wings hyaline (B) Genaemirum varianum (Tosquinet)

- Lower gena not expanded into a backward curved protuberance (a); wings infuscate (b) Genaemirum fumosum Broad, Rousse & van Noort
