Nothing is known about the biology of Monomorium subdentatum.
Bolton (1987) - A member of the M. opacum complex in the M. salomonis species group. Known only from a couple of syntypes and a short series from Kienge, Zaire, subdentatum is only feebly separated from opacum. Further collections may well provide intermediates in the characters mentioned above. A series from Kienge (in MCZ) differs from the syntypes as the alitrunk of the worker has a few minute standing hairs on the promesonotum and a quite densely hairy first gastral tergite. Whether this series represents a separate species, or whether the syntypes of subdentatum have been badly abraded, remains to be decided.
