worker only described .

Forel's (1907a) description is at .

This description is typical of Forel's refusal to denote species, preferring to designate new subspecies or varieties. Here he wrote of - "TL 2.7-3 mm; differs from the type [gallicola] by the propodeal spines being as long as more than half the distance between their bases; by the deep median notch dividing the postpetiole entirely in two; and, a much stronger sculpturation, very fine and dense strations on the head and alitrunk and across the occiput, sculpture which gives the insect a silky appearance, the pedicel nodes also are subopaque. Some individuals from Arusha-Chini have the mesonotum with raised lateral tuberculiforme sections posteriorly with slight concavity between them"; from Moshi near the River Rau & Arusha-Chini, collector Katona.

The type and fresh specimen below are smaller and darker than Crematogaster gallicola.
