Hister circularis Lewis, 1889

This species together with H. barkeri Desbordes constitutes a very distinct group of African species which may be characterized by presence of a triangular frontal fovea ( Fig. 8), by very slightly rounded mesosternal margin, by doubly margined prosternal lobe ( Fig. 11) and by curious shape of the male genitalia ( Figs. 12-15). In consideration of these features it is highly probable that the creation of a new genus is needed but a resolving of this problem requires additional studies.
