Dorsum of head smooth, postclypeal notch weaker, reticulation on thoracic dorsum slightly stronger. Scape slightly surpassing the occiput. Pronotum less shouldered; mesonotum dropping less sharply posteriorly and median carina effaced; propodeum slightly wider between the spines. Petiole node with a longer anterior edge.

Crematogaster (Sphaerocrema) bequaerti For. variety atraplex Santschi new variety; in Wheeler (1922: 155). Described as: "Length 4 mm. Rather dull yellow; gaster, postpetiole and femora yellowish brown; tips of the epinotal spines brownish black. In other respects like the type of the species and the var. mutabilis (Santschi), but the median impression of the pronotum is feebler. The dark tips of the spines contrast with the pale color of the thorax.” (Santschi). A dozen workers from Yakuluku (Lang and Chapin).
