A new entodiniomorphid ciliate species, Gorilloflasca africana n. g., n. sp. was described from the Virunga mountain gorillas, Gorilla beringei beringei, in Rwanda. It is characterized by a flask-shaped body, a long tubular vestibulum, a round frontal lobe, a large posterior cavity, an ellipsoidal or peanut-shaped macronucleus and a single contractile vacuole. G. africana has the adoral and the vestibular ciliary zones in the buccal area. The adoral ciliary zone is non-retractable, encircling the vestibular opening. The vestibular ciliary zone extends posteriorly in the vestibulum. The somatic ciliary zones are the cavity ciliary zone in the posterior cavity along the ventral side of its opening and two longitudinal ciliary zones on the dorsal body surface. The buccal infraciliary bands of G. africana are a C-shaped adoral polybrachykinety, a stick-shaped vestibular kinety band, and paralabial kineties. The anterior region of the vestibular kinety band is composed of short kineties whereas, kineties in the remaining region are longitudinal. The somatic infraciliary bands are a cavity polybrachykinety and two longitudinal polybrachykineties. Gorilloflasca is a member of the family Blepharocorythidae based on the non-retractable adoral ciliary zone, the frontal lobe, the large posterior cavity and the vestibular longitudinal kineties.
一种新的内毛目纤毛虫物种，非洲大猩猩吸管虫（Gorilloflasca africana），新属，新种，是从卢旺达的维龙加山地大猩猩（Gorilla beringei beringei）体内发现并描述的。它的特征是身体呈烧瓶状，有一个长管状前庭，一个圆形额叶，一个大的后腔，一个椭圆形或花生形的大核以及一个单一的伸缩泡。非洲大猩猩吸管虫在口区有口侧和前庭纤毛区。口侧纤毛区不可缩回，环绕前庭开口。前庭纤毛区在前庭向后延伸。体纤毛区是后腔沿其开口腹侧的腔纤毛区以及背体表上的两条纵向纤毛区。非洲大猩猩吸管虫的口区下纤毛带是一个C形口侧多短列毛、一条棒状前庭动列带和唇旁动列。前庭动列带的前部由短动列组成，而其余区域的动列是纵向的。体下纤毛带是一个腔多短列毛和两条纵向多短列毛。基于不可缩回的口侧纤毛区、额叶、大的后腔和前庭纵向动列，大猩猩吸管虫是Blepharocorythidae科的成员。
