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.
洞穴拟裸虫是一种新的原生动物，从乌干达野生东部黑猩猩（Pan troglodytes schweinfurthii）的粪便中分离而来。这个新物种的身体呈球形，有一个额叶，一个长长的前庭，一个位于身体背面的后肛，一个卵形的大核，一个位于后肛附近的伸缩泡，以及身体左侧的一个大凹面。口纤毛不可伸缩，由三个纤毛带组成：一个围绕前庭开口的口前带，一个在额叶基部横向延伸的背-口前带，一个在前庭中纵向延伸的前庭带，呈螺旋状排列在前庭表面。两个不可伸缩的体纤毛带构成了身体表面的拱形结构：一个短的背纤毛带在额叶基部横向延伸，一个宽的 C 形左纤毛带在左侧凹面。由于不可伸缩的口纤毛中有三个纤毛带，本属可能是 Blepharocorythidae 科的成员，但大的左侧凹面和 C 形左纤毛带是独特的，这种结构从未在其他 Blepharocorythidae 中描述过。
