Sparse, unbranched, and relatively long, hair-like test processes mainly on the proximal (ventral) half of the body, are less crowded on the sides, and the almost whole anterior half of the body, including a wide area between and around the siphons, is bare. The test and the test processes are almost smooth or have sparse sediment attached. Apertures are widely separated on the upper surface.

Body musculature consists of an external layer of regularly spaced bands of circular muscles around the whole body (especially crowded around the siphons) and an internal layer of longitudinal muscles radiating from the siphons. Fifteen short, flattened, simple branchial tentacles arise from the margin of the short branchial velum. The prepharyngeal band of two lamellae makes deep undulations (associated with the branchial folds as in

). The dorsal lamina is represented by at least 10 long triangular languets. The branchial sac has four folds on the left, and (apparently) five on the right. A group of the most dorsal vessels on the right may constitute one fold or two. The formula for the anterior part of the branchial sac is: (6)(10)(12)(4)(6)DL(11)(8)(10)(12). The middle longitudinal vessels on each fold do not reach the bottom of the branchial sac and the number of longitudinal vessels significantly decreases toward the posterior end of the branchial sac. Only transverse stigmata are present, the stigmata under the branchial folds are longer than the stigmata on the sides of the folds (as in

Two or three large, lobed testis follicles are between the ovary and the body wall, their rounded lobes projecting slightly from the sides and posterior end of the ovary. The male duct runs along the mesial surface of the ovary from the posterior testis follicles terminates near the almost sessile oviductal opening. One or two lateral branches join it along its length. The gut forms a wide, closed loop. A long oesophagus is clearly demarcated from the short cylindrical stomach. The stomach has five or six deep longitudinal folds but a gastric caecum was not detected. The anal border is smooth. Endocarps are not present.</paragraph>
