Specimen Labels

Specimen labels note collections from Victoria Desert, Casuarina, and clay soils of a minesite. These vague, eclectic notes are all that is known about the biology of Monomorium megalops.

Identification

Heterick (2001) - A member of the monomorium group. Apart from the shape and size of its eye, M. megalops is virtually identical with Monomorium sordidum, and may eventually prove to be no more than a variant of that widespread species.

Heterick (2009) - Monomorium megalops is identical to Monomorium sordidum, apart from its large, reniform eye.
