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).
