Monomorium mictilis

This species has been found in open woodland and shrub habitats.

Identification
Heterick (2006) - A member of the M. exiguum complex in the M. monomorium species group.

Bolton (1987) - As presently constituted (a wide distribution in the Afrotropical region; perhaps more than one species is present) this minute species is identified by its size, arrangement of alitrunk pilosity and flattened head, in combination with the 11-segmented antennae.

Distribution based on Regional Taxon Lists
Afrotropical Region: Angola, Eritrea, Ethiopia, Guinea, Kenya, Mali, Namibia, Sudan, Zimbabwe.

Worker
Bolton (1987) - TL 1.2-1.3, HL 0.36-0.40, HW 0.26-0.30, CI 72-76, SL 0.20-0.26, SI 77-86, PW 0.16-0.19, AL 0.32-0.36 (10 measured).

Median portion of clypeus distinctly prominent and its anterior margin transverse to shallowly convex, sometimes with a minute indentation at the site of the median seta. Clypeal carinae weakly developed but present. Maximum diameter of eye 0.20-0.22 x HW. In general the eye when viewed in profile consisting of an outer ring of ommatidia encircling a single longitudinal row of only 2-3 ommatidia, but in some individuals one or two extra ommatidia may also be enclosed in the ring. Eye always distinctly longer than high and situated well in front of the midlength of the sides of the head. Antennae with 11 segments; the scape, when laid straight back from its insertion, conspicuously failing to reach the occipital margin. Head capsule in profile dorsoventrally flattened, the ventral surface approximately flat and not more convex than the dorsum. Promesonotal dorsum in profile flat or only extremely shallowly convex anteriorly, the metanotal groove only very weakly impressed. Propodeal dorsum convex and sloping posteriorly, the dorsum and declivity forming a single broadly convex surface. Propodeal spiracle small. Petiolar peduncle short and stout, subtended by a narrow strip-like and inconspicuous ventral process. Petiole node low and bluntly triangular in profile, distinctly larger than the much more broadly rounded postpetiole. Standing hairs present on all dorsal surfaces of the head and body, the promesonotal dorsum with only 3 pairs. Anterior margin of pronotum without a pair of elongate standing hairs between the distinctive pair at the pronotal humeri. Sculpture absent except for short metanotal cross-ribs. Colour dull yellow.
