Specimen Labels

Tetramorium peringueyi has been found nesting in sandy soils and in deep dolerite reddish soils. The nests normally have more than one entrance. They occur in open areas at the basal parts of plants, often with a crater of soil around the entrance. This species feeds on seeds and stores them inside the nest; seed stores have been recorded within 8 cm of the soil surface. In one of the samples collected, the larvae and alates were found at about 22 cm down. Pitfall trapping, sugar baiting and hand collecting have been used to collect this species. (Mbanyana et al. 2018)

Identification

Mbanyana et al. (2018) - Tetramorium peringueyi is morphologically similar to Tetramorium dichroum, Tetramorium margueriteae and Tetramorium brigitteae. They all have numerous simple, erect hairs covering the body. This species is separated from T. dichroum and T. brigitteae by the presence of erect hairs on the leading edges of the antennal scapes, whereas the other two species only have a sub-erect pubescence. Tetramorium peringueyi and T. margueriteae can be distinguished based the characters listed under T. margueriteae.
