Identification

Bolton (1987) - A member of the M. bequaerti complex in the M. monomorium species group. Of the Afrotropical species in which the antennae are 11-segmented three, bequaerti, Monomorium pulchrum and Monomorium rosae, have a relatively large and characteristically shaped postpetiole. Among these three species rosae is a fairly common West and Central African form which is very dark in colour, being blackish brown to black. The other two are much lighter, and apparently less common. M. pulchrum from Zimbabwe is dull yellow and bequaerti from Zaire is glossy light brown. Apart from its colour bequaerti is characterized by its relatively high narrow petiole node which in dorsal view is longer than broad. In both other species the petiole node is conspicuously broader than long in dorsal view.

Description

Worker

Bolton (1987) - TL 1.9, HL 0.50, HW 0.38, CI 76, SL 0.36, S1 95, PW 0.25, AL 0.54.

Clypeal carinae moderately strongly developed and widely divergent anteriorly. Maximum diameter of eye 0.21 x HW and with 5 ommatidia in the longest row. Outer ring of ommatidia enclosing more than one longitudinal row. In full-face view the eyes conspicuously in front of the midlength of the sides and the scapes, when laid straight back, failing to reach the occipital margin. Antennae with 11 segments. Sides of head evenly very shallowly convex in full-face view, the occipital margin exceptionally shallowly concave, almost transverse. Promesonotal dorsum in profile convex, sloping posteriorly to the shallow and only feebly impressed metanotal groove. Propodeum convex and broadly rounded, the spiracle pinhole-like. Nodes of petiole and postpetiole longer than broad in dorsal view. In profile the petiole node a high, relatively narrow, bluntly subconical structure. Subpetiolar process a narrow rim anteroventrally. Postpetiole in profile with a shallowly convex anterior face, broadly rounded dorsum and very long gradually sloping posterior face , the postpetiole relatively large, about the same size as or even slightly larger than the petiole. Except for small hair-pits, cross-ribbing at the metanotal groove and some faint vestiges on the pleurae sculpture is absent from the head and body; all surfaces except those mentioned being smooth and highly polished. All dorsal surfaces of head and body with standing hairs present, the promesonotum with 5 pairs. Colour a light glossy brown.

Type Material
