Characters. A. fatidica is a species of small size (body length ♂ 20–25 mm, ♀ 29 mm) (Fig. 7). Stål (1873) described the male from Sierra Leone, and later Karsch (1893) described the female from Togo; it has been recorded by Karsch (1889, 1890, 1893) from Sierra Leone, Barombi Station (Cameroon) and Togo, by Griffini (1908) from Mukonje Farm (Cameroon), and by Chopard (1954) from Mt. Nimba (Ivory Coast and Guinea). This species has a shiny black spot at the base of the tegmina. Fore femora have 3–4 ventral spines, mid femora 2–4 ventral spines and hind femora with a double row of 6–7 yellow ventral spines with a black tip. Male cerci are short and slightly curved; at about middle of the cerci an inner stout, slightly flattened and pointed spine with a black tip is typical; the apex of the cerci is bifid, pointed and apically hairy (Figs 74a, 74b). Styli are present. Ovipositor is short without lateral protuberances.

Distribution. Species with a probably wide distribution in West and Central Africa (records from Sierra Leone, Guinea, Ivory Coast, Togo, Cameroon).
