Distribution. Senegal, Guinea, Ivory Coast, Burkina Faso, Ghana, Bénin, Niger, Nigeria, Cameroon (Giglio-Tos 1913; Gillon & Roy 1968; Prost & Roy 1986; Roy 1962b, 1967, 1969, 1971b, 1975, 1978).

Remarks. Widely distributed across the Sudan savanna belt. Amorphoscelines are bark runners feeding mainly on ants (Roy 1963; Schwarz 2018). The enlarged and partially blackened last segments of the cerci (Fig. 40) are used for displaying during snake-like bending movements of the posterior half of the abdomen, a behavior analogous to the foreleg waving or “boxing” of other mantodeans.
