Head wider than neck, separated from trunk by a distinct neck constriction. Cephalion and epipleurae clearly demarcated, hypopleurae only inconspicuously marked. Trunk widest at ca U50, gradually tapers towards furca base (U80). Mouth ventral, no cuticular teeth. Hypostomium bears two parallel cuticular lamellae. Pharynx without dilatations. Intestine straight, with a marked anterior section. Scales spined, three-lobed, not overlapping, distributed in 14 columns, 12 scales per column. Scales and spines increase gradually in size in a posterior direction. Dorsal surface covered with: (i) small head and anterior neck scales with a small, broadly rounded anterior lobe, equally long posterior lobes, and marked transition between anterior and posterior lobes; (ii) small posterior neck scales with a slightly elongated anterior lobe and an indistinct transition between anterior and posterior lobes; and (iii) comparatively big and triangular trunk scales. Interciliary field covered by (i) small, oval to oblong scales without keels; (ii) a pair of small, oval scales with a keel; (iii) a single distinctly bigger, oblong, and keeled scale; and (iv) a pair of big, very narrowly ovate, and spined scales. Furca branches about as long as adhesive tubes, with lateral margins more or less straight, furcal indentation shallowly U-shaped, adhesive tubes well-developed. Ventral side of furca branches covered with minute, oval to oblong, and keeled scales.</paragraph>

). Body width is ca 18 µm at U10, ca 26 µm at U50, and ca 29 µm at U60. The head is relatively wide, with a plate-like, slightly narrower cephalion. The neck (ca U13–U27) smoothly continues to the trunk, which is distinctly wider than the head, gradually dilates from about U37 to U50 where it reaches the maximum width. Then it gradually tapers towards U80 where the curved margins of the furca branches begin to emerge. Dorsal sensory bristles arise from the cuticle in two pairs at U23 and U60 (

Two pairs of cephalic ciliary tufts emerge laterally between the cephalion and the anterior edge of the epipleurae (ca U3) as well as close to the posterior edge of the epipleurae (U6). The mouth ring is oval, ca 4.6 µm in the largest diameter, located subterminally at U2–U4.

INTERNAL MORPHOLOGY. The pharynx extends from ca U5 to U27, is about 28 µm long and 6.5–8.9 µm wide, sinuous, and has no dilatations. The cerebral ganglion appears as a mass surrounding the pharynx along its whole length. The intestine runs from U27 to U81 and has a separate, well-differentiated anterior section (U28–U31).

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 14 longitudinal rows, with 13 scales in the central dorsal row. Their size increases in a posterior direction. Central dorsal and dorsolateral longitudinal rows of scales begin at ca U5 (behind the posterior edge of the cephalion), while lateral rows start at the posterior end of the epipleurae (ca U13). Ventral rows start at U10 and exhibit a horizontal zonation pattern. Four main
