Eurhopalothrix

These ants are infrequently encountered although they can be locally common. They are most often found in leaf litter samples and decaying wood. Nests are in soil under rocks and in cracks in rocks and range from small to quite large. Although detailed studies have not been undertaken, a species of Eurhopalothrix from Papua New Guinea has been found to accept a wide range of soft-bodied arthropods with a preference for collembolans.



Worker of E. australis from Queensland.

Identification
The antennae are 7 segmented (including the scape) and when laid back against the head in their normal resting position, are held in distinct, elongate depressions (antennal scrobes) which pass below the eyes. The mandibles are triangular and when fully closed they touch or nearly touch along their entire length. These ants are most similar to Rhopalothrix, but differ in having triangular rather than thin, elongate mandibles.
