Pseudonotoncus

These uncommon ants have been found primarily foraging on vegetation and tree trunks, both during the day as well as at night. The only known nest was found in soil. Nothing more is known of their biology.

Identification
Two pairs of spines are present on the propodeum and one pair of rearward-directed spines are present on the top of the petiole. The mesosoma is heavily sculptured with distinct ridges.

Species of Pseudonotoncus can be recognised by the spines on the propodeum and petiole. Some species of Stigmacros are similar in having spines on the propodeum and the petiole, but they are much smaller in overall size and have 11 segmented antennae (Pseudonotoncus has 12 segmented antennae).
