Strasser (1971a) described two subspecies of ausugi, viz., fimbriatus and gentianae. Considering
the gonopod conformations of the two latter forms, both of which differ significantly from S. ausugi
comb. nov. and are instead much more similar to S. illyricus comb. nov., S. maximus comb. nov.,
S. montellensis comb. nov., and S. rotundatus comb. et stat. nov., it becomes obvious that
Strasser (1971a) treated the modified mouthparts as a taxonomic feature of primary importance, being
unaware of the adaptive nature of such modifications, as revealed later by Enghoff (1985). Thus we
here elevate fimbriatus and gentianae to the species level and describe both of them in detail below.
