. Body wall without outer papilla-like or branchial formations. Segment number 23–39 or more. Asexual reproduction by architomy. No eyes, no proboscis, no intestinal dilatation. Coelomocytes present. Dorsal bundles of chaetae from II, with one, rarely two, hair and one, rarely two, simple-pointed or bifid, or trifid needle chaetae. Bifid and trifid needles mostly in anterior segments, simple-pointed chaetae mostly in posterior segments; in IV always peculiar, enlarged simplepointed needle chaetae. Ventral chaetae from II, commonly 3–5 per bundle, bifid. Anterior and subsequent ventral chaetae are similar in shape and size, with upper teeth somewhat longer than the lower in the first 4–7 segments, the teeth approximately equal in length in the 3–5 following segments, and the upper teeth a little shorter than the lower afterwards.

Bifid and trifid needle chaetae mainly in the anterior part of the body, within the first 7–17 segments, excluding IV, which normally bears enlarged simple-pointed needles. In single cases bifid needles in more posterior bundles. Trifid needles less common than bifid needles, absent in anterior segments. As previously noted, bifid and trifid needles may alternate with the regular simple-pointed needles in different segments. In some individuals bifid and/or trifid needles absent.

Anterior and subsequent ventral chaetae alike, bifid, moderately s-shaped, more curved towards the posterior end of the body, 47–72 μm in length and 1.8–3.1 μm in width, with a feebly marked, slightly distal (anteriorly) or slightly proximal (posteriorly) nodulus (
