with a 203 to 240 μm body length; adhesive tubes 27 to 32 μm long. Pentalobed head with two pairs of sensory ciliary tufts. Cephalion, epi- and hypopleurae present; hypostomium not observed. Strong and short rod-like reinforcements lining the walls of the mouth ring, pharynx with posterior dilation, and a narrow pharyngealintestinal junction. Scales distributed in 12 to 14 columns, with 20 to 26 scales. Pentalobed dorsal scales, increasing in size from neck to trunk and decreasing at the base of the furca. Rounded scales with small spines in the interciliary ventral area, two rows of unilobed oval scales in the ventral region of the furca. Dorsal spines with denticles positioned in the final third of the body; spines increasing in size from neck to trunk, decreasing at the base of the furca; two pairs of long spines without dorsal and ventral denticles at the base of the furca. Spines without denticles in the furcal base greater than the length of the adhesive tubes.

). The scales and spines increase in length along the ventral body, respectively, from 2 μm and 6 μm (U19) to 4 μm and 8 μm (U59).A pair of longitudinal locomotor ciliary bands are present between U5 and U60 (fig. 2E). The ciliary bands converge medially at the base of the furca (U93) (fig. 2E). The length of the locomotor cilia increases from 6 μm around U7, to 7 μm at about U28 and finally to 9 μm at U66 (fig. 2E).

On the other hand, our specimens also have slight morphological variations, mainly related to morphometric features such as body length, head, neck and pharynx length and width (
