Diagnosis

Body size 30-70 x 1-1.8 mm. Segment number 70-130. Easily identified by the annular clitellum covering XIII-XX and marked ventrally by two longitudinal grooves connecting the prostate pores (in XVII, XIX) and male pores (in XVIII) of each side (Fig. 2). A gizzard occurs in VII, and the calciferous glands appear as paired sausage-shaped diverticula originating posteriorly in IX. Paired spermathecae in VIII and IX, opening in the anterior intersegment below chaetal line c. The thin tubular prostates, when fully distended, occupy 3-7 segments.
