. 3 times longer than wide; surface sculpture complex, comprising numerous variably shaped patches of fine tubercles each encircled by a smooth, very narrow margin, the patches set in a coarser tuberculate/punctate groundmass, a little finer apically; costal margin distinctly convex; basal cell short and broad, not extending to midpoint of PCu; R evenly convex, parallel with costal margin, the basal R cell therefore of about equal width for entire length; two
