Identification
Bolton (1987) - A member of the M. malatu complex in the M. monomorium species group. M. affabile and Monomorium malatu are very closely related and eventually may even prove to be synonymous. Apart from a few minor differences (see below) the main discriminating features which presently separate the two are the dimensions and ratios, as follows.
- affabile TL 1.5. HW 0.34, CI 81, SL 0.30, SI 88, PW 0.22, AL 0.40.
- malatu TL 1.9-2.1, HW 0.38-0.46, CI 88-92, SL 0.33-0.38, SI 80-85, PW 0.26-0.28, AL 0.50-0.54.

Description
Worker
Bolton (1987) - TL 1.5, HL 0.42, HW 0.34, CI 81, SL 0.30, SI 88, PW 0.22, AL 0.40.
Answering the description of malatu but smaller, with a narrower head and longer scapes; see comparative dimensions below. Clypeus constructed as in malatu but carinae sharply developed, divergent anteriorly and reaching the anterior margin at the anterolateral angles of the projecting portion of the clypeus. Maximum diameter of eye 0.24 x HW, and with 5 ommatidia in the longest row. With the head in full face view the sides subparallel.
Type Material
Bolton (1987) - Holotype worker, Zaire: Banzyville (R. P. Augustin) (Naturhistorisches Museum, Basel) [examined].
