Abstract

ABSTRACT. Troglocorys cava n. g., n. sp. is described from the feces of wild eastern chimpanzee, Pan troglodytes schweinfurthii, in Uganda. This new species has a spherical body with a frontal lobe, a long vestibulum, a cytoproct located at the posterior dorsal side of the body, an ovoid macronucleus, a contractile vacuole near the cytoproct, and a large concavity on the left surface of the body. Buccal ciliature is non-retractable and consists of three ciliary zones: an adoral zone surrounding the vestibular opening, a dorso-adoral zone extending transversely at the basis of the frontal lobe, and a vestibular zone longitudinally extending in a gently spiral curve to line the surface of the vestibulum. Two non-retractable somatic ciliary zones comprise arches over the body surface: a short dorsal ciliary arch extending transversely at the basis of the frontal lobe and a wide C-shaped left ciliary arch in the left concavity. Because of the presence of three ciliary zones in the non-retractable buccal ciliature, the present genus might be a member of the family Blepharocorythidae, but the large left concavity and the C-shaped left ciliary arch are unique, such structures have never been described from other blepharocorythids.
