Small worms without a proboscis. Dorsal pharyngeal pad present. All chaetae simple-pointed. No lateral blood vessels in posterior segments. First pair of nephridia pre-clitellar, on 6/7. A single testicular segment, with testes paired in VIII or IX, ovaries paired in IX or X. Male pores one pair, behind ventral chaetae in VIII or IX; spermathecal pores one pair, behind ventral chaetae in the first post-atrial segment. Atria elongate and tubular to petiolate; male pores either on short porophores or on penes formed by extrusion of elongated lining cells from a muscular penial structure. A single pair of male funnels on the posterior septum of the atrial segment; one posteriorly-directed vas deferens per atrium; vasa deferentia do not penetrate posterior septum. Female pores on chaetal lines at posterior septum of first post-atrial segment. Spermathecal ducts narrow-elongate; ducts may terminate in vestibules; spermathecal ampullae globular to ovate with large, vacuolated cells entally.
