is likely due to contraction during preservation. The peristomial rings are more obvious in specimens where the pre-setiger region appears shortened, likely due to contraction. The presence of a mid-dorsal groove on the anterior thoracic segments is difficult to observe and may be an artifact of preservation. The pigmentation present along most of the body in preservative is either reddish or brown; this pigment is faded in some specimens or entirely absent. In most specimens, the dorsal tentacles and branchiae are missing, but when present, they are often short, not elongate. In the largest specimens, the swollen middle section is also longer and encompasses more segments. In general, the prostomium is short, not elongate as in
