Two new entodiniomorphid Triplumaria ciliates from the intestine of the wild African white rhinoceros.
Two new species of Triplumaria in the order Entodiniomorphida, T. alluvia n. sp. and T. grypoclunis n. sp., are described from the large intestine of the wild African white rhinoceros. T. alluvia has three bud-shaped caudalia, one broad skeletal plate with a wavy left dorsal edge, and an axe-shaped tail flap. T. grypoclunis has three short arched caudalia, two broad skeletal plates, and a pointed and ventrally curved tail flap. These two new species have a C-shaped adoral polybrachykinety, a slender perivestibular polybrachykinety, and paralabial kineties in their retractable adoral ciliary zone. In T. alluvia, the perivestibular polybrachykinety is joined to both ends of the adoral polybrachykinety and paralabial kineties along the ventral side of the adoral polybrachykinety, showing the same arrangement as in Cycloposthium species. In T. grypoclunis, the perivestibular polybrachykinety is joined only to the right end of the adoral polybrachykinety and paralabial kineties along the left ventral side of the adoral polybrachykinety, showing an arrangement analogous to the Tripalmaria species.
