Synonyms

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).

Distribution

Boer et al. (2020): All records of M. sahlbergi originate from desert-like, urban, industrial, and military areas ranging from sea level to an elevation of 1800 m. It is not clear from our research what the original geographic region of M. sahlbergi was. Based on the distribution of other species in the salomonis group, the native distribution would include specimens from the Indomalaya region (Nepal, India, Thailand). Our data came from the following main geographic regions: Palearctic (China, Israel, Netherlands (interception)), Australian (New Zealand, from likely interceptions), Nearctic (USA, in part interceptions), Neotropical (Panama, Galapagos), Afrotropical (Reunion, Madagascar) and Oceania (Hawaii).

Distribution based on Regional Taxon Lists

Afrotropical Region: Socotra Archipelago, Yemen.
Oriental Region: India (type locality), Pakistan, Sri Lanka.
Palaearctic Region: China, Israel (type locality), Oman.
