with head delineated from trunk by means of a constriction; posterior end broadly expanded, often rounded or truncated, or tapered into a medial process. Anterior adhesive tubes (TbA) 2–7 per side, located posterior to buccal cavity in vicinity of neck constriction and often borne on extensible feet; ventrolateral adhesive tubes (TbVL) present, with several to many pairs occurring along pharyngeal and intestinal regions, but may be absent from pharyngeal region; dorsal adhesive tubes (TbD) mostly absent, so far only known from one species; posterior adhesive tubes (TbP) 10–20, rarely fewer, located on lateral and posterior borders of caudal end, and may be separated into groups on either side of midline or may merge almost indistinguishably with TbVL. Cuticle thin, without armament, but often with granular appearance, epidermal glands are mostly absent but exist in two species. Pharyngeal length in adults about one-third total body length; intestine more or less divisible into broad anterior secretory region and narrower posterior absorptive region. An unpaired dorsal ovary is located posterior to U50, eggs mature in a caudal direction, one or few eggs mature at a time; paired testes at both sides of the intestine in the anterior part of the trunk (approximately U25–U50), caudally directed sperm ducts often fuse into a ventral unpaired gonopore; frontal organ present, caudal organ only known in some species. Locomotory cilia cover entire ventral region of head and then extend posteriorly as two longitudinal columns along the neck and trunk; both columns fuse into a narrow field of cilia at the posterior end. Ring-shaped field of sensory cilia on the dorsal side of the head. Stiff sensory cilia evenly spaced along the trunk in lateral and/or dorsolateral rows.
