Specimen labels

The only species in the genus, the types (workers only) were collected in a pitfall trap. Although it is not uncommon in the Darling Range, Nebothriomyrmex majeri is particularly abundant in coastal peppermint (Agonis flexuosa) scrubland around Bremer Bay. Here, many clusters of ant colonies can be found in white sand under rotted wood and around tree and shrub roots. Given their close association with roots in these circumstances, they may be tending root aphids or other Hemiptera. (Heterick 2009)

Identification

Worker. Palpal index 6:4. Eyes small (with about 20 facets), situated near antennal sockets; simple ocelli absent. Antennae 12-segmented. Mandibules with 4 or 5 small teeth. Median hypostoma developed, without emargination. Metanotal depression deep. Main surface of propodeum situated distinctly below mesonotum. (Dubovikoff, 2004)
