Sulabanus pendolensis species group

Definition of the species group. This group of species is characterized by the stout, robust phallus which is not emarginate at the apex (Figs. 27–38, compare with Figs. 39–50). When phallus is widest in the middle of its length (e. g. Figs. 31, 35, 41, 43), the ratio between widest part at midlength of the phallus and the narrowest part in the apical half of the phallic length does not exceed 1.8. Altogether, nine species are classified in this group: Sulabanus pendolensis, S. lalui, S. rufomarginatus, S. brunneus, S. dumongabonensis, S. lineatus, S. katarinae, S. gracilis, and S. ambangensis .
