Forel's
(1902g) description is at . Forel (1909e: 384) gave
a fuller, amended
description, this is at ; he also gave notes on
the preferred habitat, of full desert, which sets diehliii part
from most related species, this is at . Santschi (1929b) gave notes on diehlii,

Collingwood (1985: 287) noted - "This shining black ant
is
also distinctive in having the funiculus segments shorter than in C.
bicolor or C. niger and allied species. The first funiculus
segment [see below] is about x 1.3 as long as the second compared with
about 1.8 x as long in the C. bicolor group and on this
character alone apart from the colour difference, cannot be regarded as
a subspecies of C. bicolor.
