Mycetophylax Genera
Klingenberg & Brandão (2009) revised a collection of species that were considered to belong to the genus Mycetophylax. They proposed that these species actually belonged to three genera and provided the following key to determine their placement.
1
- Subtriangular head, without psammophore. Posterior margin of postpetiole straight, without any median impression. Color light to dark brown. Lives exclusively in dunes and “restingas” of the Atlantic Ocean; preferring arid habitats with sandy soil => Mycetophylax
- Quadrate or subquadrate head, long setae at clypeus forming a psammophore. Posterior margin of postpetiole with a median impression. Color reddish-brown or brownish. Not restricted to Atlantic Ocean beaches => 2

return to couplet #1
- Clypeal psammophore setae arising close to the anterior margin of the clypeus; median clypeal seta present; clypeal latero-posterior margins not strongly produced as rounded ridges. Postpetiole triangular when seen from above. Frontal lobes triangular and well developed. Color brownish => Paramycetophylax
- Clypeal psammophore setae arising from the midportion of the clypeus medially and at the posterior margin laterally; median clypeal seta lacking; clypeal latero-posterior margins strongly produced as rounded ridges, resulting in a large circular area where the antennal scapes articulate. Postpetiole heart-shaped when seen from above. Frontal lobes reduced, but almost covering the antennal insertions. Color reddish-brown => Kalathomyrmex
