Autapomorphies of Ironopsis/g1. (1) In larva long dense hairs of anterior margin of head shield [see Epeorus/fg2 (2)] are directed not anteriorly as in other Epeorus/fg2, but medially-dorsally, pressed to the head and one to another (Kluge 2004: Fig.65:I). (2) Penis lacks latero-dorsal spines [see Pentamerotarsata (5)]. Non-unique apomorphy: these spines independently disappear in some other Radulapalpata, including some Epeorus/fg4. Character of Ironopsis/g1 of unclear phylogenetic status. (3) On tergalius I anterior widening [see Iron/g1 (1)] is always widened distally (the same in some Iron/g2). |
