P. Y. Parkhaev and Y. Demidenko 2010 | "Hollow, asymmetric, pyramidal sclerites. Sclerites curved, forming right and left handed varieties. Sclerites merge each other by lateral sides, forming group of sclerites with common base, arranged in one or two rows. Cross-section of base of sclerite group is oval or quadrangular. Transition between base and sclerite blade gradual. Sclerites usually flattened, gradually narrowing towards distal end. Distal end of sclerite blind, rounded or pointed." |
