Diagnoza

Symmetrical elements (tr) of the apparatus with flat external side and with only five keels.

Porównanie

Costate elements of W. nakholmensis differ from those of related species by having fewer longitudinal keels. The elements of the anteriormost two pairs (ne-hi) are morphologically transitional between those of W. costatus and W. ethingtoni in that they have wide ned but not alate
bases . NOWLAN (1981) was the first who properly recognized the apparatus of the species (and genus)
and included in his reconstruction the smooth element types shared also by species of Scalpellodus .
