Key to Terataner workers

Bolton (1981) revises the genus. No species have been described since then.

Antwiki keys are based on this reference, are valid and cover all the species for the Afrotropical Region.

 * Dorsal (outer) surfaces of hind tibiae with projecting hairs. With the head in full face view the frontal carinae posteriorly sharply angled outwards, forming a ridge or row of tubercles which run towards the sides .....2


 * Dorsal (outer) surfaces of hind tibiae without projecting hairs. With the head in full face view the frontal carinae fading out in a straight line, not sharply angled outwards .....3

 * Eyes more or less flat, not or only weakly breaking the outline of the sides of the head in full-face view. Sides of pronotum in dorsal view strongly convergent posteriorly. Black species; dorsal surfaces of alitrunk with abundant stout hairs…..Terataner bottegoi


 * Eyes convex, conspicuously breaking the outline of the sides of the head in full-face view. Sides of pronotum in dorsal view roughly parallel, not strongly convergent posteriorly. Head and gaster black; alitrunk red; dorsal surfaces of alitrunk with sparse short hairs …..Terataner transvaalensis

 * Yellow. Pronotal dorsum distinctly broader than long. Pronotal width almost equalling to distinctly exceeding the combined lengths of pronotum and mesonotum in dorsal view…..Terataner luteus


 * Dark brown to black, the alitrunk usually reddish, lighter than the head and the gaster. Pronotal dorsum as broad as long. Pronotal width less than the combined lengths of pronotum and mesonotum in dorsal view …..Terataner elegans
