Nothing is known about the biology of Monomorium personatum.

Identification

Bolton (1987) - A member of the M. bicolor complex in the M. salomonis species group. M. personatum is distinguished from all other members of the complex by its relatively large eyes, the maximum diameter of 0.31-0.33 x HW contrasting with the combined range of 0.19-0.27 x HW shown in the remainder of the complex (Monomorium bicolor, Monomorium dictator, Monomorium hirsutum, Monomorium rufulum, Monomorium westi). The dense gastral pilosity shown by personatum, as well as its large eyes, differentiates it from bicolor, the species with which it was originally associated as a subspecies.
