Biology

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.

Castes

Known only from the worker caste.

Worker

Worker measurements (n=l). OOD 0.34, EL 0.24, HL 0.96, EW 0.13, HW 0.97, CNW 0.05, CND 0.09, SL 0.69, AL 1.10, PpW 0040, SW 0.38, CI 1.02, CNI 1.61, REL 0.24, ScI 0.71, SpIIA6. Head very broad (HW >0.95, CI <1.00); area between propodeal spines concave; gastric dorsum without erect hairs; body colour black.

Head finely punctate and superimposed with fine strigulate sculpturing; area near the mandibular insertion with a narrow area of strigulate SCUlpturing. Head with a few erect hairs between the frontal lobes and on the clypeus. Erect and suberect hairs absent from antennal scapes. Pronotum weakly imbricate dorsally, nearly smooth laterally and lacking erect hairs. Mesonotum and propodeum finely and closely punctate. Propodeal spiracles similar to tridens. Medial propodeal carina expanded posteriorly and limited to the basal face of the propodeum. Propodeal spines projecting postero-Iaterally, with the outer surfaces concave, the distal ends approximately the same width as the maximum propodeal width, and the area between them concqve. Erect hairs absent from gastric tergites. Body colour black; anterior and venter of head, legs and clypeus reddish black; mandibles reddish black posteriorly, yellowish red distally; tarsi dark yellowish red.
