Genus Iteaphila Zetterstedt, 1838

Figs 4B , 6B, 6E, 6H , 8C

Diagnosis

The synapomorphies of this genus and Anthepiscopus are the loss of epipharyngal blades and the tergite 10 fused with the cercus in females. Both males and females possess a straight labrum, in contrast to Hormopeza spp., where only males possess a straight labrum. Further similarities with species in Anthepiscopus are the setose scape, the loss of costal bristle and the recurved CuA in the wings (except for ‘ Iteaphila setosa -group’ for the latter two characters). The species in the genus are distinguished from those of Anthepiscopus by having a branched R 4+5.
