Synonyms

Besides the fact specimens have been collected from forests, nothing is known about the biology of Axinidris hypoclinoides.

Identification

Snelling (2007) - Antennal scape shaft without erect hairs and pronotum with 1 pair of long erect hairs and each propodeal spine with 1 long erect hair; head (excluding clypeus) with 2 pairs of erect hairs; medial propodeal carina absent; first tergum with 2 long erect hairs; gena shiny and finely imbricate; head and body yellow.

The presence of a single pair of relatively long erect hairs on the pronotal disc and a single such hair at the apex of each propodeal spine is an unusual feature shared only with Axinidris bidens, a larger and darker species. Both species are present in the Kakamega forest of Kenya, but A. bidens is encountered much more frequently.

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

Shattuck (1991) - (as parvus) Worker measurements (n=2). OOD 0.22, EL 0.13-0.17, HL 0.53-0.61, EW 0.06-0.09, HW 0.45-0.52, CNW 0.05, CND 0.03-0.04, SL 0.38-0.42, AL 0.72-0.76, PpW 0.21-0.24, SW 0.14, CI 0.85-0.86, eNI 0.65-0.74, REL 0.29-0.32, ScI 0.81-0.83, SpI 1.49-1.52.

Small (HW <0.53); area between propodeal spines smooth, without a medial carina; pronotum with 2 elongate, erect hairs; each propodeal spine bearing a single distinct, erect hair; head and alitrunk reddish yellow, contrasting with darker yellowish red gaster.

Head weakly coriarious dorsally, smooth laterally and ventrally; pilosity limited to one pair of erect hairs on the frontal lobes and one pair on the clypeus. Erect and suberect hairs absent from antennal scapes. Pronotum smooth; mesonotum and propodeum imbricate (weaker on anterior and lateral niesonotum). Pronotum with one pair of elongate hairs dorsally. Propodeal spiracles with the posterior surface only slightly depressed below the level of the anterior surface. Medial propodeal carina absent. Propodeal spines reduced to lateral angles partly connected by a carina, each bearing an elongate, erect setae, and with the area between them slightly concave. Erect hairs present on all gastric tergites. Head and alitrunk reddish yellow, gaster yellowish red, legs, petiole, antennae and mandibles yellow.
