Medium-sized species, 140–160 µm in total body length. Head five-lobed with two pairs of short, scanty ciliary tufts. Furca forcipate, 19–20 µm long, with reduced proximal part and pointed adhesive tubes. Dorsal surface covered by 4-6 columns of anteriorly rounded and posteriorly indented smooth scales with straight simple spines. Lateral spines on average two to three times as long as the dorsal spines. Posteriormost dorsal and lateral spines, up to 39–40 µm in length, positioned in the posterior trunk region. Posterior to these spines the dorsal trunk is covered by 7 columns of smaller keeled scales. Ventral interciliary area covered by rectangular transverse scale plates with jagged anterior edges. Posteriormost interciliary area covered by small, rounded, triangular, keeled scales with very short simple spines. Pharynx 29–30 µm in length.

Medium-sized species with a stocky tenpin-shaped body, 140–160 µm in total body length. Head five-lobed with scarcely cuticularized cephalion, 13 µm in width, and pleuria. Two pairs of short and scanty sensory ciliary tufts; posterior pair with longer cilia than anterior pair.

Body width 23–28 µm at the head (U08), approximately 20 µm at the neck (U19), 26–30 µm at the trunk (U59) and 15–16 µm at the base of the furca (U83). Head delimited from trunk by neck constriction that gradually widens into the trunk, which reaches its greatest width approximately 2/3 of the way down the length of the body. Furca forcipate, 19–20 µm in length, elongate with pointed adhesive tubes. Proximal parts of furcal branches are naked and reduced. Two pairs of dorsal sensory bristles, anterior pair anchored at U17. Dorsal surface covered by 4–6 columns with 19–21 anteriorly rounded and posteriorly indented smooth scales with straight simple spines. Length of scales and spines increases towards the posterior end. On the head, scales are widely spaced and are a quarter or less of the size of the largest scales of the trunk region. Scales of the trunk region measure 8–12 µm in length and 6–9 µm in width. The dorsal spines are 5–6 µm long at the neck and 15–20 µm long in the trunk region. The lateral spines are on average three to four times as long as the dorsal spines. The posteriormost 4 long, up to 39–40 µm in length, dorsal and lateral simple spines, are situated at U

the posterior trunk region. Posterior to these spines the dorsal trunk is covered by seven columns of smaller keeled scales in 5 rows. Most of them do not carry spines but five more or less median spines and a pair of short parafurcal spines are situated at the posteriormost end of the dorsal trunk. These spines are 8–12 µm long and much shorter than the furcal branches.
