COMMENTS: Chromosomal data were reported by Gautun et al. (1985) for the sample from Burkina Faso . Rosevear (1969) included angelus in this species, but Sicard et al. (1988) discussed its possible specific status. The form nigeriae was provisionally considered valid by Rosevear (1969) but was referred to a subspecies of T. gracilis by Robbins (1974) .
