Nomenclature

 *  convexiceps. Strumigenys (Codiomyrmex) convexiceps Santschi, 1931c: 277, figs. 9, 10 (w.) CUBA. Combination in Codiomyrmex: Weber, 1934a: 52; in Glamyromyrmex: Brown, 1948e: 116; in Pyramica: Bolton, 1999: 1672; in Strumigenys: Baroni Urbani & De Andrade, 2007: 117.

Worker
Bolton (2000) - Mandibles in full-face view and at full closure triangular, strongly tapering apically; MI 26-30. Distal of the basal lamella with 3 short triangular teeth that are slightly recurved and whose apices fail to meet, or only just meet, at full closure. These are followed by 2 elongate curved spiniform teeth, the first of which (tooth 4 from the base) is at the top of a marked downcurvature of the blade, so that the remaining teeth form a more or less vertical apical series below the fourth. Tooth 6 also elongate but shorter than 5, followed by two very short teeth or denticles and terminating in a slightly larger apical tooth, to give a total dental count of 9. Other differences from Strumigenys nitens are noted below.

Type Material
