The following newly developed identification key to species groups is loosely based on Bolton (1982) and Mbanyana & Robertson (2008), and also incorporates ideas from Snelling (1992).
Identification key to Afrotropical Nesomyrmex species groups (workers)
1. Antennae with 11 segments ( Fig. 2A View Fig ); petiolar node and postpetiole with conspicuous and very well developed lateral spines ( Fig. 2B View Fig ) …………………………………… N. cataulacoides group
– Antennae with 12 segments ( Fig. 2D View Fig ); petiolar node and postpetiole never with conspicuous and very well developed lateral spines as above, at most petiolar node with small, lateral denticles ( Fig. 2C View Fig , E–F) ………………………………………………………………………………………2
2. Anterior clypeal lobe short, flat-margined, and never convex, lobe with a small median triangular projection ( Fig. 3A View Fig ); pronotum anterodorsally sharply marginate, with sharp, dentate corners ( Fig. 2C View Fig ); petiole barrel-shaped with very weakly developed, short and triangular petiolar node ( Fig. 3B View Fig ) ……………………………………………………………………… N. humerosus group
– Anterior clypeal lobe always conspicuously developed, usually convex and variably rounded, sometimes flat, but never with a small median triangular projection ( Fig. 3C View Fig ); pronotum anterodorsally either rounded or weakly marginate but without sharp, dentate corners ( Fig. 2 View Fig E–F); petiole variably shaped, but never as above, usually with very well developed petiolar node ( Fig. 3D View Fig ) ……………………………………………………………………………………………………3
3. Propodeal spines present and conspicuous, usually long and narrow, in profile distinctly longer than their basal width ( Fig. 4 View Fig A–B); hairs on dorsum of mesosoma always present, short, and blunt ( Fig. 4 View Fig A–B) …………………………………………………………………… N. angulatus group
– Propodeal spines usually absent ( Fig. 4D View Fig ), if present, then very short and broad, in profile no longer than their basal width ( Fig. 4C View Fig ); hairs on dorsum of mesosoma variably developed: usually long, fine and acute, sometimes absent, and only very rarely short and blunt …………………… ……………………………………………………………………………………… N. simoni group
