Body length 133 µm, body width 31 µm, 20 µm, 38 µm and 9 µm at head, neck, trunk and base of furca respectively. Head with well developed hypopleuria and well delimited from trunk by a constricted neck. Posterior trunk region greatly reduced in width. Furca straight, 14 µm in length, with adhesive tubes pointing slightly outward at their distal ends. Anterior sensory bristles absent, posterior sensory bristles present. Dorsal body surface covered by suboval to round scales, with poorly developed edges, distributed in 16–17 columns with 22–24 scales in each. Dorsal scales absent above anterior part of pharynx, scales on either side of this area are hemi-elliptical and arranged diagonally relative to the longitudinal body axis. Ventral interciliary area naked except in the posterior part where thin, smooth, round, reduced and overlapping scales are present. Pharynx without swellings, 37 µm in length.

is a mid-sized species, 133 µm in total body length. Head appears three-lobed but is weakly five-lobed, shaped as an isosceles trapezoid. Cephalion 14 µm in width, epipleuria barely visible while hypopleuria are large and well developed. Hypostomium present as a smooth kidneyshaped plate just behind the mouth. Two pairs of cephalic ciliary tufts present. The cilia of the posterior tufts are approximately 20 µm in length and those of the anterior tufts 5–8 µm in length. Ocellar granules absent.

Head well delimited from trunk by a constricted neck, which gradually widens into the trunk. The posterior trunk region is drastically reduced in width from 38 µm at U60 to 9 µm at U81, into a tapered furca base. The furca is more or less straight, 14 µm in length. Adhesive tubes 11 µm in length, almost parallel, pointing slightly outward at their distal ends.

The edges of the scales are poorly developed and may be partly fused with the cuticle. The dorsal part of the head above the pharynx and down half the length of the pharynx naked.

The scales situated laterally on either side of the naked portion are hemi-elliptical, half as wide as long and diagonally arranged relative to the longitudinal body axis. The median dorsal scale column is straight while the columns on either side tend to diverge, progressively approaching parallelism with the lateral body outline. Just anterior of the caudal cutting there are two medial keeled scales. The base of the furca also bears two pairs of dorsal keeled scales diagonally arranged relative to the longitudinal body axis, the outer pair being half the size of the inner pair. Two pairs of larger keeled dorsolateral scales are also present on the furca. Ventrolaterally in the anterior portion of the body, the keels form short stout spines. These spines become progressively fused with the scales towards the posterior end. The posterior part of the ventral interciliary area with apparently weakly developed, rounded, smooth, reduced, partially overlapping scales. Ventral ciliation in two separate longitudinal bands not merging on the head.</paragraph>
