Emery's (1896i) description is at {original description}. Forel's (1907c) description of aethiops is at {original description}. Santschi's (1914a) description of sellula is at {original description}. Santschi's (1914a) description of subsulcata is at {original description}. Santschi's (1926b) description of bayeri is at {original description}. Emery (1897e: 598) noted that the variety cincta was generally paler than the type being yellow brown, with head and gaster darker.


Note: with fresh specimens from acacia in Sudan that appear to be close to the description given by Emery (1896i) for the species Crematogaster chiarinii variety cincta, I separated the distinct forms with a general yellow-brown or red-brown colour and darker gaster, with paler appendages to a separate species here described.
The aethiops form is a puzzle as Forel (1907c) noted is as collected with the variety cincta in the spines of acacias but as being black or near black, with very short propodeal spines and a the occiput more distinctly impressed.  This suggested it might be yet another species. The availability of type images from Antweb (February 2014) show little difference between the forms, however. 

Wheeler (1922) has many records from East Africa and into Saudi Arabia. It seems very likely that those were mostly if not all cincta.

Collingwood (1985) separated "C. chiarinii" from other species recorded from Saudi Arabia by - head wider than long; petiole about as wide as long; alitrunk paler than head or gaster, propodeal spines more than 0.2 mm; also more strongly sculptured than affabilis (type location Somalia); mesonotum with keel.
