Rhytidoponera tyloxys

These ants may be specialist predators, unlike most Rhytidoponera (Andersen 2000).

Identification
Heterick (2009) - Possibly consisting of a complex of two or more species, this highly distinctive taxon has an unmistakeable appearance, since the node is produced as a sharp spur or tooth directed posteriad.

Distribution
Heterick (2009) - can be found in the extreme north and probably also in the eastern fringes of the SWBP.
