Sulabanus utarensis species group

Definition of the species group. The two species that are placed in this group share a characteristic very slen- der phallus with the apical part partly membranous and a very long, slender, rod–shaped internal sac (Figs. 59–62). The high similarity of male genitalia of these species suggest the close relationship of these species. The pronotal carinae form seven areolae, but the middle frontal carina is very strong in the frontal part and very weak posteriorly.
