Head wider than neck, separated from trunk by an inconspicuous neck constriction. Cephalion, epipleurae, and hypopleurae clearly demarcated. Trunk gradually widens from ca U37 to U60 and then gradually tapers towards furca base at U80. Mouth ventral, with delicate protruding structures, no cuticular teeth. Pharynx without dilatations. Intestine straight, with a marked anterior section. Scales spined, three-lobed, not overlapping, distributed in 10–12 columns, 15 scales per column. Spines with a short lateral denticle. Scales and spines increase gradually in size in a posterior direction. Dorsal surface covered by scales from posterior end of cephalion (ca U3) to furca base (ca U93). Furca base short, lateral margins of furca branches more or less straight, furcal indentation deeply U-shaped, adhesive tubes well-developed, almost parallel. Furca base and branches covered with oval, keeled scales.</paragraph>

). Body height in lateral view is 14.0–15.0 µm at U10, 15.0–15.4 µm at U50, and 16.1–17.0 µm at U60. The head is relatively wide, with a plate-like, rounded cephalion. The neck (ca U12–U27) smoothly continues to the trunk, which is significantly wider than the head, gradually dilates from about U37 to U60 where it reaches the maximum width. Then it gradually tapers towards U80 where curved margins of the furca branches begin to emerge. Dorsal sensory bristles arise from the cuticle in two pairs at U12 and U79 (

SCALES. Almost the entire body is covered by not overlapping three-lobed scales that adhere to the basal cuticle layer along their whole perimeter. Scales are distributed in a minimum of 12 longitudinal rows, with 10 scales in the central row. Their size increases gradually in a posterior direction. Central dorsal and dorsolateral longitudinal rows of scales begin at the level of the anterior edge of the epipleurae (ca U5), while lateral rows start at the posterior end of the hypopleurae (ca U13). Ventral rows are hardly visible due to the thick, elongated dorsal spines (for further explanation, see below) and long locomotory cilia. Three main

VENTRAL CILIARY BANDS AND VENTRAL INTERCILIARY FIELD. Unfortunately, the ventral side could not be observed in detail due to the thickness of the dorsal spines that precluded turning over and squeezing the worms. Moreover, the ventral locomotory cilia also hampered detailed observations of the ventral side. Despite these problems, the following observations could be done. The longitudinal ciliary bands begin at ca U10 and run backward to ca U85. The ciliary bands are accompanied by two ventrolateral rows of small (2.0–2.9 ×1.9–2.2 µm in size), three-lobed scales that start at U13. The interciliary field bears small (1.7–2.6 ×0.9–1.2 µm in size), oval scales without spines or keels (
