goertzi group

Consiglio (1967) diagnosed this group by the presence of ridges in the medial penial armature ( Fig. 34), but given recent developments it appears that this group is paraphyletic. Both I. bosnica Aubert, 1964 , currently treated as a member of the oxylepis group, and I. citrina sp. n., have these ridges. They also exhibit character states that align them clearly with the rivulorum group. I propose the dissolution of the goertzi group and transfer of I. goertzi Illies, 1952a and I. citrina to the rivulorum group, whereas I. bosnica is assigned to the oxylepis group.
