Specimen Labels

This species remains known only from the two type specimens from roadside vegetation in an unspecified locality in Nigeria, but assumed to be the Gambari Experiment Station (Shattuck, 1991).

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.

Description

Worker

(n=2). OOD 0.26-0.28, EL 0.22, HL 0.83-0.86, EW 0.12-0.13, HW 0.75-0.76, CNW 0.05-0.06, CND 0.07-0.08, SL 0.68-0.69, AL 1.01, PpW 0.37-0.38, SW 0.24-0.25, CI 0.88-0.91, CNI 1.28-1.31, REL 0.29, ScI 0.91, SpI 1.29-1.34.

Antennal scapes without erect or suberect hairs; pronotum with c. 6 erect hairs; outer surface of propodeal spines flat; CNI <lAO.

Head smooth to weakly coriarious with widely spaced shallow punctures and weakly developed scabriculous sculpturing posteriorly and laterally (absent from vertex and area ventral of eye); area near the mandibular insertion with a narrow area of strigulate sculpturing. Numerous erect hairs on the dorsal surface of the head from the occipital border to the anterior clypeal margin. Erect and suberect hairs absent from antennal scapes (occasionally 1 or 2 hairs present). Entire pronotum and antero-dorsal surface of mesonotum smooth, remaining mesonotum and entire propodeum finely punctate. Pronotum with c. 6 erect hairs. Propodeal spiracles as in tridens. Medial propodeal carina slightly expanded dorsally, and located posterior of a line drawn between the propodeal spiracles to just anterior of the petiolar insertion. Propodeal spines directed posteriorly with the outer surfaces flat, the distal ends narrower than the maximum width of the propodeum, and the area between them nearly flat. Erect hairs present on gastric tergites 2, 3 and 4. Body colour dark reddish brown to reddish black with the propodeum and gaster darker; petiole, antennae and mandibles yellowish red; tarsi reddish yellow.

Type Material

Holotype worker and one worker paratype from NIGERIA (specific locality not given, probably Gambari Experiment Station) (E. Taylor) (The Natural History Museum).
