Nothing is known about the biology of Monomorium braunsi.


Bolton (1987) - A member of the M. boerorum complex in the M. monomorium species group. This minute yellow species is distinguished from its close relatives Monomorium mavide, Monomorium musicum and Monomorium torvicte by its very reduced alitrunk pilosity and low broadly rounded petiole node. The subpetiolar process of braunsi is very reduced, being represented only by a low anteroventral prominence rather than the anteriorly truncated longitudinal cuticular strip seen in the other three species mentioned.

Bolton (1987) - TL 1.6, HL 0.43, HW 0.33, CI 77, SL 0.27, SI 82, PW 0.20, AL 0.44.

Clypeal carinae of this minute species short, clearly visible only on central third of length of median portion of clypeus, fading out both anteriorly towards the free margin and posteriorly between the antennal insertions. Anterior clypeal margin evenly convex across central portion, without conspicuous angles or denticles separating the anterior and lateral borders of the median prominent section of the clypeus. Eyes relatively small, only 0.18 x HW and with 5 ommatidia in the longest row. In full-face view the eyes very distinctly in front of the midlength of the sides of the head. Antennal scapes, when laid straight back from their insertions, falling far short of the occipital margin. Sides of head very shallowly convex in full-face view and divergent posteriorly from front to back so that the width across the occiput is obviously greater than the width across the clypeus. Occipital margin nearly transverse, with only the feeblest hint of concavity medially. Head in profile dorsoventrally compressed, the ventral surface more convex than the dorsal. Promesonotum low and only weakly convex in profile, the metanotal groove very shallowly impressed and traversed by short cross-ribs. Propodeal dorsum shallowly convex and rounding broadly into the declivity. Propodeal spiracle minute and pinhole-like. Petiole with a short stout anterior peduncle, the latter with a small inconspicuous anteroventral process. Node of petiole low and broad in profile, broadly rounded above and with a bulging convex ventral border. Postpetiole smaller and lower than the petiole, its dorsal surface somewhat more broadly rounded. Cephalic dorsum with several pairs of standing hairs but alitrunk with only a single pair, situated at the pronotal humeri. Petiole, postpetiole and gaster all with standing hairs visible. Sculpture absent except for minute hair-pits and metanotal cross-ribs. Colour uniformly yellow.
