Adlerzia

Adlerzia contains a single species and is limited to Australia. Specimens are infrequently encountered. They nest under stones as well as in the soil without coverings. Little is known about their biology.

Identification
The antennae are 11 segmented. The upper surface of the head is smooth and there are no antennal scrobes. The front margin of the clypeus just above the mandibles has pairs of elongate hairs or setae which straddle the mid-line of the head but there are no central hairs. The clypeus has a pair of longitudinal ridges or sharp angles immediately below the antennal sockets which separate the central region from the lateral regions (clypeus longitudinally bicarinate). The petiole has a distinct, rounded node. There are major and minor workers but no intermediates (dimorphic).

These ants are most likely to be confused with species of Anisopheidole, Machomyrma or possibly Pheidole because of the generally similar body size and shape and the presence of major workers. They can be separated by their 11 segmented antennae and bicarinate clypeus.
