Specimen Labels

In Yemen this species was collected from a banana farm where the soil was moist and rich in decaying livestock faeces. Several pselaphine beetles were also observed in the same habitat (Sharaf et al., 2017).

Identification

Worker caste of this species can be confused with the cosmopolitan species Monomorium pharaonis (L., 1758) but it can be separated by the finely longitudinally striated head, the smooth first gastral tergite, and the dark patches in front of the eyes (Sharaf et al., 2017).
