Key to genera of Ozaenini (adapted from (1))

1a - Tibia wide and compressed, with knife-like edge dorsally; femora with deep ventral groove; front tibiae with shallow emargination ... Physea

1b - Tibia not as above; femora not or only slightly grooved .... 2

2a - Front tibiae strongly emarginate, with a prominent tooth at the base of emargination; dorsal surface with long setae; dorsal surface of mandibles not punctate; 11th antennomere dull, same width as 10th, narrowed gradually with granulate mat area on each side extending almost to the base .... Pachyteles

2b - Front tibiae only shallowly emarginate, not toothed; dorsal surface without long setae, either glabrous or with short thick setae; dorsal surface of mandbiles densely punctate; 11th antennomere shining, wider than 10th, apically narrowed with apical portion thickly granulate, mat, and wedge-shaped .... Ozaena
In the Nearctic, only found in the southwestern U.S., but overall has a pantropical distribution. (1)
Physea are thought to be myrmecophilous. Species in other genera have been taken in rotten wood and under stones. Larvae have been collected under bark and on bat guano. (1)
Mostly nocturnal predators, but Physea are myrmecophilous. (2)
