Diagnosis
ReferenceDiagnosis
P. Y. Parkhaev and Y. Demidenko 2010"Hollow elongated asymmetrical sclerites of three distinct morphotypes, i.e., palmate, cultrate, and siculate types. Each sclerite composed of distinct base and blade, which is several times longer than base. Base usually bent towards lower side of sclerite, forming variable angle with blade. Base usually bears foramen, which often repeat shape of cross-section of sclerite base. Sclerites bent to different extent. Upper surface of sclerite usually convex, bears longitudinal (rarely transversal) ribs and carinae, sometimes ornamented by tubercles. Lower surface flattened or concave, smooth or with transversal striation."
