Nomenclature

 *  micrositus. Camponotus (Manniella) micrositus Wheeler, W.M. 1937b: 462 (w.) CUBA.

Worker
Minor. Length 3 mm.

Differing from the described species of Manniella in its very small size and in color. Head subtrapezoidal, narrowed anteriorly, with convex sides and very convex vertex and posterior border. Eyes large and moderately convex, half as long as their distance from the anterior corners. Mandibles narrow, with oblique, apparently 4-toothed apical borders. Clypeus feebly and evenly convex, ecarinate, with the anterior border projecting and broadly rounded in the middle, narrowly sinuate on each side. Frontal area transverse, indistinct; frontal carinae rather straight, strongly diverging posteriorly. Antennae slender; scapes extending about one-fourth their length beyond the median occipital convexity of the head. Thorax narrower than the head, short and high, about twice as long as broad, with distinct but not impressed promesonotal and without traces of a mesoepinotal suture, from above subtriangular, broad through the pronotum, rapidly narrowing to the posterior end of the epinotum, which is less than half as broad as the pronotum, the pleurae distinctly and evenly convex. From above the pronotum is twice as broad as long, semicircular anteriorly, somewhat flattened above and submarginate at the sides; the thorax in profile evenly and rather strongly convex as far back as the epinotal declivity which is sloping, distinctly concave and as long as the distance from its anterior end to the promesonotal suture. Petiolar scale rather thick, as thick above as below, with flattened anterior and posterior faces and very blunt superior border, which is broadly rounded when seen from behind. Gaster about as large as the thorax. Legs moderately long, fore femora incrassated.

Shining; mandibles sub opaque, very finely granular. Head, thorax, petiole and appendages• delicately reticulate, the meso- and metapleurae more coarsely and therefore appearing more opaque. Gaster finely, transversely shagreened or striolate.

Erect hairs yellow, sparse, rather short, bristly and of uneven length, on the legs present only at the tips of the femora. Appressed hairs, or, pubescence sparse, coarse, long on the pronotum and first gastric segment, shorter and more numerous on the clypeus and cheeks.

Head, thorax, petiole and first gastric segment red, remainder of gaster black; mandibles, posterior portion of head and first gastric segment more brownish red; legs and antennae somewhat paler and more reddish yellow.

Type Material
Described from a single specimen taken on the coast below Pico Turquino, Sierra Maestra, July 26, 1936.
