Aenictus philiporum

This rare species has been collected only a limited number of times on Cape York Peninsula, Queensland and in eastern Papua New Guinea. Little is known concerning its biology (Shattuck, 2008).

Identification
A member of the pachycerus group. Head capsule smooth posteriorly and weakly punctate between the frontal carinae and above the mandibular insertions; pronotum with large smooth areas dorsally and laterally, other areas micro-reticulate.

Distribution based on Regional Taxon Lists
Australasian Region: Australia. Indo-Australian Region: New Guinea.

Biology
A colony from Bandong was found running in file during the late afternoon in midmountain rain forest. The workers wer carrying brood consisting of half-grown larvae; thus the colony is interpreted as being in the nomadic phase. Three Pheidole soldiers, representing at least 2 species, were retrieved from the mandibles of the the workers. (Wilson 1964)

Castes
Known only from the worker caste.
