Werner, 1929; Villiers, 1956) Hulselmans new and Roman precise (1969, 1980), & Verheyen (1970), and Hughes (1983) reported the species from Burkina Faso, Togo, and Ghana, respectively Recent fieldwork revealed the presence of Dorr's Racer Trape in & Benin, Guinea, and southern Mauritania (Chippaux, 1999;
