Nomenclature

 *  flavidulus. Macromischa flavidula Wheeler, W.M. & Mann, 1914: 37, fig. 15 (w.q.) HAITI. Combination in M. (Antillaemyrmex): Mann, 1920: 408; in Antillaemyrmex: Wheeler, W.M. 1931b: 32; in Leptothorax: Baroni Urbani, 1978b: 441; in Temnothorax: Bolton, 2003: 271.

Worker
Length 1.5-1.7 mm.

Head somewhat longer than broad, as broad in front as behind, with evenly convex sides, nearly straight posterior border, rounded posterior corners and the moderately convex eyes at the middle of the sides. Mandibles with rather straight external and finely denticulate apical borders. Clypeus convex, with broadly rounded anterior border. Frontal carinae subparallel; frontal area indistinct. Antennal scapes reaching to the posterior border of the head; club of funiculus large, 3-jointed; remaining joints, except the first, small, broader than long. Thorax short, about as long as the head with the mandibles, a little broader in front than behind, in profile with evenly rounded, convex dorsum, without any traces of promesonotal or mesoepinotal sutures; humeri rounded, epinotum sloping, without distinct base and declivity,bearing two spines which are longer than the declivity and much longer than their distance apart, curved downward and directed backward and outward. Petiole with a short, slender peduncle, bearing a small, acute tooth on its ventral surface, and a node which is longer than broad, with its anterior declivity in profile sloping and slightly concave, its summit slightly flattened and its posterior declivity very short and convex. Postpetiole large, broader than long, three times as broad as the petiole behind, in profile rounded and convex above. Gaster small, at the base only a little broader than the postpetiole. Legs rather short; femora slightly incrassated.

Whole surface of body very smooth and shining.

Hairs white, blunt, short, scattered and erect on the body, very minute and appressed on the scapes and legs.

Yellow; mandibles, antennae, epinotal spines, legs and venter paler and more whitish.

Queen
(dealated). Length: 3.3 mm.

Differing from the worker in the following characters: The head is subcircular, not longer than broad, with more convex sides. The epinotal spines are shorter and stouter and not curved, the upper surface of the mesonotum is flattened and the gaster is large and elongate elliptical, the postpetiole even broader in proportion to its length. The wing insertions, a spot on the scutellum, a broad band across the first gastric segment and a much narrower band near the posterior border of each of the following segments are brown.
