Opis

Diagnosis. - All the elements in the apparatus ornamented only with a delicate longitudinal striation (ke- sp) or almost smooth (ne-hi).

Remarks.-The present meaning was given to the genus by LOFGREN(1978) who identified several chronospecies in the Baltic materials. Originally Dzik erroneously attributed to this genus also ne and hi elements (they are not diagnostic at the generic level) which actually belong to Walliserodus, a more
advanced member of the family.
