Nothing is known about the biology of Monomorium subdentatum.
Identification
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.

Description
Worker
Bolton (1987) - TL 3.1-3 ·3, HL 0.80, HW 0.63-0.66, CI 79-83, SL 0.66-0.68, SI 103-105, PW 0.42, AL 0.94-0.98 (2 measured).
Answering the description of Monomorium opacum but differing as follows:
subdentatum - In profile propodeal dorsum and declivity meeting in a sharply defined or subdentate angle. SI 103-105. Anterior free margin of median portion of clypeus concave.
opacum - In profile propodeal dorsum and declivity rounding together, not meeting in a sharp angle. SI 90-100. Anterior free margin of median portion of clypeus convex.
Type Material
Bolton (1987) - Syntype workers, Zaire: Katanga, Elisabethville, 23.iv.1912 (Bequaert) (Musee d'Histoire Naturelle Genève; Musee Royal de I' Afrique Centrale) [examined].
