A. angustipennis is a small species (body length ♂ 21 mm). Chopard (1954) described the male from Guinea (Yanlé). Naskrecki (2009) recorded it from Ghana. Tegmina are broad (ratio length/width: 4.3, Chopard 1954), fore femora are clearly longer than pronotum (10 vs. 5.5 mm) ( Fig. 4 ). Fore femora have 5 ventral spines, mid femora 4 and hind femora 7 ventral spines on both sides. Male cerci are stout, up- and in-curved, with a blunt apex with a ridge armed with 1 spinule and a hooked spine; before the apex a robust lateral spine is present ( Figs 72a, 72b ).
