KEY TO GENERA OF THE PROCIRRINA

1. Abdominal segment VII with tergum and sternum partially (figs. 33, 34) or completely fused; abdominal segments IV to VI with pair of windows in intersegmental membrane adjacent to tergum and sternum (figs. 24, 28).................... 2

– Abdominal segment VII with tergum and sternum separated; abdominal segments IV to VI without windows in intersegmental membrane..................... 3

2. Abdomen without imbricate macrosculpturing, surface strongly punctate (fig. 24); tergum and sternum VII fused at base and with apical incision (figs. 33, 34); elytra without long, prominent seta on lateroapical angle (fig. 14); ( Mexico and Caribbean to Brazil; southern Europe and Africa, southern Asia to Japan, and Australia)............................. Oedichirus

– Abdomen with diamond-shaped, imbricate macrosculpturing, surface without noticeable punctation (figs. 27, 28); tergum and sternum VII completely fused, without incision; elytra with long, prominent, thicker seta on lateroapical angle (fig. 96); ( Canada to Argentina; Africa, India, southeastern Asia to Japan, and Australia)... Palaminus

5 (4). Head pedunculate, postocular region strongly tapered to narrow, nearly parallel-sided pedicel (figs. 7, 52); labrum quadridentate (fig. 55); antennomere 11 slightly longer to shorter than 9 and 10 combined; (Canary Islands, southern Europe, Africa, southern Asia to Japan, and Australia)...
