Measurements. Males. Body length: 26.8±1.1; pronotum length: 6.2±0.2; pronotum height: 6.0±0.1; hind femur: 22.0±1.6; tegmina: 36.8±2.1 (syntype: 38.2); tegmina width: 9.8±0.2 (syntype: 11.4); tegmina length/width: 3.4–4.0 (syntype: 3.3); tegmina width/pronotum length: 1.4–1.7. Female (syntype). Body length: 30.5; pronotum length: 6.5; hind femur: 22.0; tegmina: 35.5; tegmina width: 12.0; tegmina length/width: 3.0; tegmina width/ pronotum length: 1.8.

Chopard (1954) described both sexes from Guinea. Later, Ragge & Roy (1971) recorded it from Sierra Leone, and Naskrecki (2009) from Ghana.

A. brevipes is a small species (body length ♂ 25–28 mm, ♀ 30.5 mm), related to A. angustipennis , but with broader tegmina and shorter legs [fore femora slightly longer than pronotum: 8 vs. 7 mm according to Chopard (1954), 7.5–7.8 vs. 6.0– 6.5 in the here investigated specimens] ( Fig. 4 ). The anterior part of the pronotum is narrow and the general aspect from above is very narrow. Tegmina have a black marking at their base and the metanotum is darkened. The stridulatory file is very short (ca. 1.5 mm) and consists of ca. 80 evenly spaced teeth ( Fig. 51 ). Fore femora have 6–7 ventral spines on inner margin, mid femora 0–2 on inner and 3–6 on the outer margin, the hind femora 5–6 small ventral spines on the inner and outer sides. Male cerci have an inner spine about midway, are apically rounded and the tips are shaped like a flat blade ( Fig. 75 ). Styli present.

Distribution. West Africa (records from Guinea, Sierra Leone, Ghana and Ivory Coast).
