The number and setation of notogastral setae of Scapheremaeus are also remarked in the paper.Type specimens are deposited in the Institute of Zoology, the Chinese Academy of Sciences.1 Scapheremaeus retestriatus sp. nov.

Notogaster divided into meddle field and marginal zone, bearing 5 and 10 pairs of setae respectively. Humeral region having a slightly hook like process directed anterolaterally. Middle field of notogaster showing a pattern of reticulation, but marginal zone bearing irregular short ridges.Holotype (W8968,slide),24.
