| Axinidris denticulata|
(Wheeler, W.M., 1922)
A. denticulatum was described from two workers collected from fire wood. Two additional specimens, collected from swollen stems of Cuviera spp. at Masaki (between Masisi and Walikale, Zaire), were also examined by Wheeler. This species is still known only from the three type specimens. Shattuck (1991) selected as lectotype the only specimen that is in fair condition; the two lectoparatypes are so covered with mold that they are nearly worthless for diagnostic purposes. (Shattuck 1991, Snelling 2007)
Snelling (2007) - Antennal scape without and pronotum with erect hairs; medial carina present and distance between spines less than PPW; mesonotum without rugae; medial carina rounded in profile; gastral tergum 2 densely punctate.
Shattuck (1991) - A. denticulatum is similar to Axinidris kinoin in the pilosity of the head, pronotum and gaster, the sculpturing of the alitrunk, and the configuration of the propodeal spines and medial carina. However, A. denticulatum differs in having less developed scabriculous sculpturing and fewer punctures on the head, a lighter body and tarsal colour, and smaller size.

Species of Axinidris appear to nest exclusively within hollow plant stems, both living and dead, and in rotten wood. They are found in forested areas throughout the Afrotropical region, but are most abundant and diverse in the moist equatorial forests. Workers are primarily arboreal foragers, but may occasionally forage in ground litter.
Known only from the worker caste.

Shattuck (1991) - (n=1). OOD 0.30, EL 0.19, HL 0.79, EW 0.10, HW 0.71, CNW 0.05, CND 0.08, SL 0.62, AL 0.91, PpW 0.37, SW 0.25, CI 0.90, CNI 1.53, REL 0.27, ScI 0.88, SpI 1.31.
Propodeal spines directed posteriorly with the area between them fiat; HW between 0.60 and 0.80; CNI >1.50.
Head smooth posteriorly, weakly imbricate and superimposed with widely spaced, weak scabriculous sculpturing anteriorly; area posterior to eyes covered with large, widely spaced shallow punctures. Area near the mandibular insertion with a narrow area of strigulate sculpturing. Head with one pair of erect hairs posterior to the eyes and numerous erect hairs anterior to the posterior margin of the frontal lobes. Erect and suberect hairs absent from the antennal scapes. Pronotum smooth with a few widely-spaced erect hairs. Anterior mesonotum weakly imbricate, posterior and lateral mesonotum and entire propodeum punctate. Propodeal spiracles similar to tridens. Medial propodeal carina slightly expanded dorsally, located just anterior of a line drawn between the propodeal spiracles to just anterior of the petiolar insertion. Propodeal spines directed posteriorly, with the outer surfaces fiat, the distal ends narrower than the width of the propodeum, and the area between them fiat. Erect hairs present on gastric tergites 2, 3 and 4. Body colour reddish brown, with the mandibles and scapes slightly lighter, and the tarsi yellow.
