Description:
This organism possesses a moderately elongated body with slight lateral compression and a prominent dorsal gibbous shape. The relatively large head is obliquely oriented towards the front and is separated from the abdomen by a distinct neck. The abdomen gradually widens for about two-thirds of its length before rounding at the posterior end. Its protective lorica consists of well-defined plates, with lateral clefts that narrow towards the front and widen towards the rear. The small, conical foot is accompanied by a short tail near the midpoint. The toes are exceptionally long, either straight or slightly curved and slender. Their basal portion is broad, tapering rapidly into nearly parallel-sided, slightly narrowing main segments, terminating in conical tips, representing about one-third of the organism’s total length.The corona, a ciliary feeding apparatus, is oblique and convex without protruding lips. A notably large mastax, equipped with typical trophi, grinds food effectively. The inner ventral edges of the rami bear comblike, denticulate lamellae near the apex. The fulcrum provides sturdy support, especially at the posterior end, while the manubria take on a strong crutched shape. The unci, resembling hook-like structures, each possess a single tooth. Gastric glands are relatively small. The elongated, sack-like ganglion contains nerve cells, and no retrocerebral organ is present. An eyespot is positioned at the front, comprising a spherical capsule, with the anterior half being transparent and the posterior half filled with pigment granules.
