Three new Troglodytella and a new Gorilloflasca ciliates (Entodiniomorphida) from mountain gorillas (Gorilla beringei beringei) in Rwanda.

Four new species, Troglodytella gracilis, T. virunga, T. dolium, and Gorilloflasca longior were described from the mountain gorillas in Rwanda.

Infraciliature of Opisthotrichum janus, Epidinium ecaudatum, and Ophryoscolex purkynjei (Ciliophora, Entodiniomorphida).

We described the infraciliature of Opisthotrichum janus, Epidinium ecaudatum, and Ophryoscolex purkynjei, belonging to the family Ophryoscolecidae, from pyridinated silver carbonate impregnated specimens. The adoral polybrachykinety is C-shaped in Opi. janus, whereas it is spiral-shaped in Epi.

Gorilloflasca africana n.g., n.sp., (Entodiniomorphida) from wild habituated Virunga mountain gorillas (Gorilla beringei beringei) in Rwanda.

A new entodiniomorphid ciliate species, Gorilloflasca africana n. g., n.

Prototapirella ciliates from wild habituated Virunga mountain gorillas (Gorilla beringei beringei) in Rwanda with the descriptions of two new species.

The morphology of Prototapirella fosseyi n. sp., P.

Bozasella gracilis n. sp. (Ciliophora, Entodiniomorphida) from Asian elephant and phylogenetic analysis of entodiniomorphids and vestibuliferids.

Bozasella gracilis n. sp. in the order Entodiniomorphida was found in fecal samples of an Asian elephant kept in a zoo.

Intestinal ciliated protozoa of the Asian elephant Elephas maximus Linnaeus, 1758 with the description of Triplumaria izmirae n. sp.

Species composition and distribution of intestinal ciliates excreted in the feces of three Asian elephants living in Sasalı National Park, Izmir, Turkey, were investigated. Seven ciliate genera consisting of 36 species were identified. This is the first report on intestinal ciliates in elephants living in Turkey; one new species, T.

Infraciliature of eight Triplumaria species (Ciliophora, Entodiniomorphida) from Asian elephants with the description of six new species.

Intestinal ciliates excreted in the feces of Asian elephants were surveyed. Fourteen species in the order Entodiniomorphida were detected. Nine Triplumaria species in the family Cycloposthiidae were found.

Redescription of Triplumaria selenica (Ciliophora, Entodiniomorphida) and its phylogenetic position based on the infraciliary bands and 18SSU rRNA gene sequence.

Triplumaria selenicaLatteur, Tuffrau and Wespes, 1970 was redescribed from pyridinated silver carbonate-impregnated specimens. Triplumaria selenica has a slit of the vestibular opening extending posteriorly along the left side of the vestibulum. The wide C-shaped adoral polybrachykinety extends along the ventral side of the vestibular opening.

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.

New entodiniomorphid ciliates from the intestine of the wild African white rhinoceros belong to a new family, the Gilchristidae.

Gilchristia artemis n.g., n.

Infraciliature and morphogenesis in three rumen Diplodinium ciliates, Diplodinium polygonale, Diplodinium leche, and Diplodinium nanum, observed by light microscopy.

Infraciliature and morphogenesis of three rumen ophryoscolecid ciliates, Diplodinium polygonale Dogiel, 1925, Diplodinium leche Imai et al., 1992, and Diplodinium nanum Imai, 1988, are described from pyridinated silver carbonate-impregnated specimens. These three species have two polybrachykineties in the buccal area and a polybrachykinety in the dorsal ciliary zone.
