“…According to this detailed revision, Family Urostyloidea includes about 34 valid genera and 154 valid species. In recent years, several new species were added to this family, which suggested that the diversity of this family of ciliates was under-estimated (e.g., Chen et al, 2011Chen et al, , 2013Fan et al, 2015Fan et al, , 2016Foissner and Stoeck, 2008;Hu et al, 2015;Jo et al, 2015;Jung et al, 2011Jung et al, , 2015Luo et al, 2015;Lv et al, 2015;Paiva et al, 2016;Shao et al, 2008a, b;Wang et al, 2011).…”

The morphology and phylogeny of two hypotrichous ciliates, Metaurostylopsis parastruederkypkeae n. sp. and Neourostylopsis flavicana (Wang et al., 2011) Chen et al., 2013 were investigated based on morphology, infraciliature and the small subunit (SSU) ribosomal RNA gene (rRNA) sequence. The new species, M. parastruederkypkeae n. sp. was identified according to its characteristics: body shape ellipsoidal, size about (165-200) × (45-60) µm in vivo, cell color reddish; two types of cortical granules including wheat grain-like and yellow-greenish larger ones along the marginal cirri rows and dorsal kineties and dot-like and reddish smaller ones, grouped around marginal cirri on ventral side and arranged in short lines on dorsal side; 26-41 adoral membranelles; three frontal and one parabuccal, five to seven frontoterminal, one buccal, and three to six transverse cirri; seven to thirteen midventral pairs; five to nine unpaired ventral cirri, five to seven left and three to five right marginal rows; and three complete dorsal kineties. Phylogenetic analysis based on SSU rDNA sequences showed that both Metaurostylopsis and Neourostylopsis are monophyletic. As the internal relationship between and within both genera are not clear, further studies on the species in these two genera are necessary. The key characteristics of all known twelve Metaurostylopsis-Apourostylopsis-Neourostylopsis species complex were updated.

Two new urostylid species, Holostichides heterotypicus n. sp. and Holosticha muuiensis n. sp., were discovered in South Korea. Morphological and phylogenetic analyses were carried out to confirm that these species are new to science. Holostichides heterotypicus is mainly characterized by the following combination of features: 110-205 μm long in vivo; 5-10 frontoterminal cirri; 6-8 midventral pairs with 2-3 midventral cirral rows; cortical granules present; four bipolar dorsal kineties; and 6-9 caudal cirri. Ontogenetic features of H. heterotypicus are similar to those of H. typicus. Phylogenetic analyses revealed that H. heterotypicus was distantly separated from bakuellid genera Apobakuella, Bakuella, Metaurostylopsis, and Neobakuella. This result is supported by the following features: transverse cirri (present in the other four bakuellids vs. absent in Holostichides) and caudal cirri (absent in the other four bakuellids vs. present in Holostichides). Holosticha muuiensis n. sp. is mainly distinguished from its congeners by the following combination of features: 100-185 long in vivo; shortened undulating membrane; cortical granules lacking; contractile vacuole absent; 51-66 adoral zone of membranelles; 42-60 macronuclear nodules; and five bipolar dorsal kineties. In the phylogenetic tree, Holosticha muuiensis n. sp. clustered with a Holosticha group (containing Holosticha diademata, Holosticha foissneri, and Holosticha heterofoissneri).

“…FOR a long time, a high degree of morphological variation and adaptation and diverse morphogenetic characteristics has brought great challenges to the taxonomy of hypotrichous ciliates. However, many new inventories have been achieved from some under-sampled or insufficiently investigated biotopes in the last decade (e.g., Chen et al 2015a;Fan et al 2014a,b;Foissner and Stoeck 2008;Foissner et al 2010;Gupta et al 2006;Heber et al 2014;Hu and Kusuoka 2015;Jung et al 2014Jung et al , 2015Kim et al 2014;Kumar et al 2014Kumar et al , 2015K€ uppers 2014;Lu et al 2014;Luo et al 2015;Paiva and Silva-Neto 2009;Singh and Kamra 2015). Moreover, some recent phylogenetic analyses have led to a better understanding of systematics and evolutionary relationships (e.g., Bourland 2015;Chen et al 2014Chen et al , 2015bFan et al 2015;Huang et al 2014;Lv et al 2015;Spakova et al 2014;Wang et al 2015;Yi and Song 2011;Zhao et al 2015).…”

The morphology and partial morphogenesis of two freshwater hypotrichous ciliates, Deviata brasiliensis Siqueira-Castro et al., 2009 and Deviata rositae Küppers et al., 2007, isolated from southern China, were investigated using live observation and protargol staining. Our populations resemble the original ones in terms of their live characters and ciliary patterns. The main determinable morphogenetic features of D. brasiliensis basically correspond with those of the type population. However, the origin of anlage V for either proter or opisthe is ambiguous: whether anlage V for the proter originates from parental frontoventral row 2 (the same as in the original population) or parental frontoventral row 3 (the same as in Deviata abbrevescens) or even de novo is not clear; the anlage V for the opisthe is possibly derived from frontoventral row 3 and further migrates to frontoventral row 2, like that in D. abbrevescens. In addition, the SSU rRNA gene was first sequenced for both species. Molecular phylogenetic analyses suggest that the genus Deviata is non-monophyletic and has a close relationship with Perisincirra paucicirrata.
