Holotype radial plate GIUS 4−564 Mrz./487/4 from the Late Givetian of Marzysz II/W/2; inner, outer, lateral and proximal view.

Diagnoza

High radial plate with a deep distal incision and lacking radial channel. Proximal processes thin and connected with each other by a thin lamella up to two-thirds of their height. Sclerites in shape of thin, commonly elliptical plates, irregularly perforated.

Porównanie

Most commonly the pores of sclerites are irregularly arranged, which precludes their classification into Eocaudiniinae subfamily.
