“…Fabreidae is sister to Folliculinidae + Maristentoridae clade, which is consistent with most of previous analyses of heterotrich systematics, however, further morphological and molecular data are needed to support this relationship (Chen et al. , ; Fernandes et al. ; Pan and Stoeck ; Shazib et al.…”

“…The grouping of Folliculinidae with Maristentoridae corresponds well with a combination of morphological and ecological similarities including a highly contractile body, a well-developed oral area with spirally arranged adoral zone of membranelles, a mainly sessile life-style and a marine or brackish habitat. Fabreidae is sister to Folliculinidae + Maristentoridae clade, which is consistent with most of previous analyses of heterotrich systematics, however, further morphological and molecular data are needed to support this relationship (Chen et al 2017(Chen et al , 2018Fernandes et al 2015;Pan and Stoeck 2017;Shazib et al 2014;Yan et al 2016).…”

Ampullofolliculina Hadži, 1951 is a monotypic genus, the only species being A. lageniformis which was first discovered in estuarine habitats in the U.S. and has never been redescribed. In the present study, we investigated the taxonomy and phylogeny of A. lageniformis Hadži, 1951 based on analyses of a population collected from a brackish wetland in Ningbo, China. The main characteristics of this species are as follows: trophont about 450–700 μm long in vivo with two short, rounded peristomial lobes of equal size; lorica flask‐shaped, transparent and smooth with a short, wide neck at the base of which two transparent valves are asymmetrically inserted; cortex with brownish to reddish cortical granules and greenish pigment granules; about 80 somatic kineties evenly arranged; moniliform macronucleus with 4–8 ellipsoidal nodules; swarmer dark green, vermiform in shape, about 200–350 μm long in vivo, with about 60 adoral membranelles and 85 somatic kineties, no mouth nor paroral membrane. Phylogenetic analyses inferred from SSU rDNA sequences show that A. lageniformis is closely related to Folliculina and Eufolliculina which nest within a large clade that comprises five families, i.e. Stentoridae, Blepharismidae, Fabreidae, Maristentoridae, and Folliculinidae.

“…The genus Gruberia was established by Kahl [15] with G. uninucleata as the type species. The morphology of Gruberia is similar to that of Spirostomum in having an elongated, slightly contractile body and a well-developed peristomial region, although the body of Gruberia lacks spiraling or torsion [6,27] Lepsi, 1965, and G. uninucleata Kahl, 1932 [15, 20, 28-32]. In their generic review, Campello-Nunes et al [5] and Chen et al [6] synonymized G. aculeata, G. beninensis and G. calkinsi with G. lanceolata, and considered G. nematodomorpha as a nomen nudum.…”

The morphology of Gruberia is similar to that of Spirostomum in having an elongated, slightly contractile body and a well-developed peristomial region, although the body of Gruberia lacks spiraling or torsion [ 6 , 27 ].

Background Heterotrichous ciliates are common members of microeukaryote communities which play important roles in both the transfer of material and the flow of energy in aquatic food webs. This group has been known for over two centuries due to their large body size and cosmopolitan distribution. Nevertheless, species identification and phylogenetic relationships of heterotrichs remain challenging due to the lack of accurate morphological information and insufficient molecular data. Results The morphology and phylogeny of two heterotrichous ciliates, namely Gruberia foissneri spec. nov. and Linostomella vorticella (Ehrenberg, 1833) Aescht in Foissner et al., 1999, were studied using rigorous methods (living morphology, stained preparations, and small subunit rDNA sequence data). Gruberia foissneri spec. nov. is morphologically very similar to G. uninucleata Kahl, 1932, however, it can be distinguished from the latter by having more ciliary rows (about 32 vs. about 20) and macronuclear shape (sausage-shaped vs. ellipsoid). Based on a combination of previous and present studies, an improved diagnosis of L. vorticella is supplied and several taxonomic anomalies are clarified. In addition, phylogenetic analyses based on SSU rDNA sequence data support the generic assignment of these two species. Conclusions Modern ciliate taxonomy should be performed by means of detailed living observation, stained preparations and molecular information. For those species that have been reported in previous studies, it is necessary to provide as much useful information as possible using state-of-the-art methods in order to resolve taxonomic anomalies.
