, a flexible cell body, and a slightly oblique anterior end that was curved to the left. This new species also had two postperistomial cirri, two contractile vacuoles, and lacked cortical granules. Under dissection microscope, these cells had a green colouration, probably due to ingested algae. On average, this new species had 27 cirri in the left ventral row, 38 cirri in the right ventral row; 50 cirri in the left marginal row; 48 cirri in the right marginal row; 9 transverse cirri, and 11 caudal cirri.

), this feature was checked carefully in 10 additional free living (i.e. not squeezed under a coverslip) individuals. The vacuoles were located along the left margin of body. The anterior vacuole was located behind the middle region of the adoral zone of membranelles (AZM). It was difficult to readily observe it because of the delayed pulsation intervals in relation to the posterior vacuole, which was located at the equatorial region of body. The anterior vacuole diastolis usually occurred after three complete pulsations (systolis and diastolis) of the posterior. Sometimes, both were observed during simultaneous diastolic condition. Both vacuoles had very short, thin and inconspicuous collector ducts that were visible only during systolis. The cytoplasm showed “L” shaped crystals of greenyellowish colouration, which were heavily concentrated at the anterior end of body.

The AZM was conspicuous, occupied 43% of average cell length, and was composed of 62–80 membranelles. The distal region of the AZM was somewhat straight and angular.

All specimens studied had two postperistomial cirri (n = 15). The anterior postperistomial cirrus was sometimes located just below the proximal end of the paroral membrane or across the outer surface of the infundibulum, which made it difficult to distinguish from the cirri in the left ventral cirral row. In contrast, the rear postperistomial cirrus was always located below the infundibulum vertex.

The left marginal row started behind the AZM and extended along the left body margin, bending to the opposite margin at the posterior region and ending past the transverse cirri, after the posterior end of the right marginal row. The right marginal row started at the level of the second cirrus of the right ventral row and extended almost parallel to the longitudinal axis through the right margin. After the equatorial region, it bent slightly inwards, ending near to the rightmost transverse cirrus, above the last two or three cirri of the left marginal row. Both marginal rows did not merge.
