P. Y. Parkhaev and Y. Demidenko 2010"Hollow asymmetrically bent or circinate sclerites with sharp lateral margins. Sclerites narrowing distally. Upper convex side of sclerite bears one or two longitudinal oblique ribs and transversal striation. Lower side well delineated by sharp margins, concave or flattened, it bears faint transversal striation. Cross-section triangular, trapezoid or polygonal in proximal part, changes its shape along sclerite length. Distal end blind, rounded or pointed."
