Crematogaster (Crematogaster) foraminiceps Santschi

Type location Kenya (Cremastogaster foraminiceps, Santschi, 1913a: 412, worker, in key; Santschi, 1914b: 89, all forms) - see below
subspecies
mirmillo (Crematogaster (Acrocoelia) forminiceps Santschi, var. mirmillo nov., Santschi, 1935b: 269, illustrated, worker) from Kenya, Mt Elgon - see below
All forms described (see Bolton, 1995) .

The form described as staitchi (Cremastogaster foraminiceps Sant. r. Staitchi n. stirps, Forel, 1915c: 339, worker & queen) from Zaïre, collected at Lumaliza, by Kohl is very different, being near black in colour that I have separated it as a distinct species - Crematogaster (Cr.) staitchi

Santschi's (1913a: 412) features listed in the key were - TL 3.4-4.3; head entirely sculptured, with irregular striations and large punctures between especially towards the occiput; promesonotum feebly concave, with rugose sculpture; yellowish brown, antennae yellow; subalpine species from 1700 m.

This is substantially larger than the type and the fresh specimen, below. The type and the latter appear to have a subpetiolar tooth that is not present on mirmillo.
