Specimen labels

The vast majority of the material examined was extracted from leaf litter samples, though occasional samples from rotten wood have been recorded. Unlike Phrynoponera gabonensis and Phrynoponera sveni, bequaerti has not been found in termitaries. (Bolton and Fisher 2008)

Identification

Almost as common and widespread as Phrynoponera gabonensis and by far the smallest species in the genus, bequaerti is easily recognised by its size, lack of clypeal teeth and short, broad funicular segments. (Bolton and Fisher 2008)

Description

Worker

Bolton and Fisher (2008) - (previously undescribed). TL 5.0-5.7, HL 1.16-1.25, HW, 1.13-1.23, CI 96-101, SL 0.90-0.97, SI 75-81, PW 0.90-1.02, WL 1.66-1.90, maximum diameter of eye 0.28-0.32, OI 24–27 (20 measured).

Mandible smooth with scattered pits, usually with 4 teeth but very rarely with 3 or 5. Median portion of clypeus with anterior margin transverse to very shallowly concave, without a tooth-like cuticular prominence on each side. Cephalic dorsum finely and densely reticulate-rugose, the bases of the reticulae punctate. Funicular segments 2-7 distinctly broader than long. Dorsum of mesosoma reticulate-rugose. Petiolar spines curve far back over the first gastral tergite; median spine at least three-quarters the length of the outer pair; intermediate spines much shorter and usually much more slender, often reduced and needle-like by comparison with the others. Gastral tergites 1-2 longitudinally costulae upon a reticulate-punctate ground sculpture; often with some anastomoses between the costulae. Colour varies considerably. In darkest forms the head and body are almost entirely black, with only the mandibles and legs reddish brown to red. From this there is a gradual increase in the amount of blackish red to dull red on most areas of the body until in the lightest colour forms the entire head is reddish, the legs are red and even the mesosoma, petiole and parts of the gaster are suffused with red.

Type Material

Bolton and Fisher (2008) - Holotype queen, DEMOCRATIC REPUBLIC OF CONGO: N’Gayu (= Ngayu), stomach Bufo superciliaris (H.O. Lang) (American Museum of Natural History) [examined].
