The following information is derived from Barry Bolton's New General Catalogue, a catalogue of the world's ants.
- exalta. Cyphoidris exalta Bolton, 1981b: 258, fig. 17 (w.) CAMEROUN.
Unless otherwise noted the text for the remainder of this section is reported from the publication that includes the original description.
Holotype. TL 4.3, HL 0.96, HW 0.88, CI 92, SL 0.74, SI 84, PW 0.64, AL 1.16.
Answering to the description of Cyphoidris spinosa in general characters but differing markedly in sculpture and pilosity, as follows:
exalta - Sides of pronotum smooth. Promesonotal dorsum weakly and predominantly transversely rugulose, with few meshes. Postpetiole in dorsal view unsculptured. Occipital corners without long fine hairs. Occipital margin and sides of head behind eyes with short, curved, decumbent to appressed hairs. Dorsal margins of frontal carinae without a spaced row of long curved hairs; such hairs also absent elsewhere on head where only very short, curved pilosity is present. Dorsal surfaces of alitrunk, petiole and postpetiole with inconspicuous short, curved decumbent hairs. First gastral tergite with short curved hairs.
spinosa - Sides of pronotum reticulate-rugose. Promesonotal dorsum strongly and conspicuously reticulate-rugose. Postpetiole in dorsal view sculptured. Occipital corners each with a single long fine hair which is prominent and conspicuous. Occipital margin and sides of head behind eyes with projecting curved hairs. Dorsal margins of frontal carinae with a spaced row of long curved hairs, such hairs also present elsewhere on head and projecting freely above the level of the shorter ground-pilosity. Dorsal surfaces of alitrunk, petiole and postpetiole with conspicuous long standing hairs. First gastral tergite with elongate projecting hairs.
Paratype. TL 4.2, HL 0.95, HW 0.85, CI 89, SL 0.74, SI 87, PW 0.62, AL 1.12. As holotype.
