“…The access to ciliate diversity and biogeography is a challenge tasks because they are diminute organisms, difficult to identify (Finlay and Fenchel, 1999), there is a lack of experienced specialists (Foissner, 2006) and a number of species stay encysted for most of their life cycles (Foissner, 2004). In Brazil, significant works were performed with this emphasis such as conducted in Rio Grande do Sul (Safi et al, 2014), Paraná (Pauleto et al, 2009;Buosi et al, 2011;Velho et al, 2005Velho et al, , 2013, São Paulo (Bagantini et al, 2013;Regali-Seleghim et al, 2011), Pará (Castro et al, 2014), Minas Gerais (Dias et al, 2008(Dias et al, , 2010 and Rio de Janeiro (Paiva and Silva-Neto, 2004a, b) states. Inventory studies constitute the first step for development of applied biotechnological usage of ciliates.…”

“…In Brazil, the first work on ciliates from freshwater environments were carried out by Cunha in the early twentieth century (Cunha, 1913;Faria and Cunha, 1917;Cunha and Fonseca, 1918) with few recent studies on inventory of these micro-organisms in inland waters (Paiva and Silva-Neto, 2004a, b;Dias, 2007;Dias et al, 2008;Regali-Seleghim et al, 2011;Safi et al, 2014;Sartini, 2012;Mendonça, 2012;Castro et al, 2014;Kuhner et al, 2016). Cotterill et al (2008) estimated that there are about 40,000 species of free-living ciliates, where only 4,500 species (~ 11%) have been described so far.…”

“…Ciliates in the class Oligohymenophorea de Puytorac et al, 1974 usually demonstrate global distribution (Kahl 1931, Dragesco and Dragesco-Kernéis 1986, Foissner et al 1994, Lynn 2008) and exhibit great biological and morphological diversity (Thompson and Kaneshiro 1968, de Puytorac et al 1974, Kaneshiro and Holz 1976, Foissner 1995, Song and Wilbert 2000, Lynn and Small 2002, Lynn and Strüder-Kypke 2005, Jankowski 2007, de Castro et al 2014.…”

Abstract. The morphology and phylogeny of two poorly known species, Uronema nigricans (Müller, 1786) Florentin, 1901 and Lembadion lucens (Maskell, 1887) Kahl, 1931, were respectively collected from a eutrophic freshwater river in Shenzhen and an oligotrophic lake in Zhanjiang (both in southern China) and investigated using standard taxonomic methods. The sampled population of Uronema nigricans was characterized by a cell size of 30-40 μm × 12-20 μm in vivo, an elongated elliptical outline with a prominent apical plate, and 13-15 somatic kineties. The sampled population of Lembadion lucens was characterized by a cell size of 45-80 μm × 20-50 μm in vivo, 25-35 somatic kineties, five or six caudal kinetosomes with cilia about 20 μm in length, and a single right-positioned contractile vacuole. The small subunit ribosomal RNA gene (SSU rDNA) of these species was sequenced and compared with those of their congeners to reveal nucleotide differences. The phylogenetic trees showed that the Shenzhen population of Uronema nigricans clusters with two other sequences under the name of "Uronema nigricans" (which are possibly misidentified) and then groups with Uronemita sinensis (Pan et al., 2013) Liu et al., 2016 with full support. Phylogenetic analyses indicated that genus Lembadion is monophyletic with full support provided by both Bayesian inference and maximum likelihood algorithms. Based on analyses of morphological and sequence data, Uronemita sinensis may represent a new genus between Uronema and Uronemita.

“…Ciliates in the subclass Scuticociliatia, commonly found in ecosystems worldwide, exhibit a great biological diversity and play important roles in marine ecosystems (Thompson & Kaneshiro 1968;Foissner & Wilbert 1981;Cawthorn et al 1996;Lynn & Strüder-Kypke 2005;Fan et al 2011aFan et al , b, 2014Pan et al 2013a, b;Castro et al 2014;Foissner et al 2014;Zhan et al 2014). Many of them are common pathogens of fishes and invertebrates and can cause severe disease or even death in economically important aquaculture animals (Pérez-Uz & Song 1995;Song & Wilbert 2002;Fan et al 2009Mallo et al 2014;Ofelio et al 2014).…”

Generally, “ophrys- related” scuticociliates belong to a specialised group of ciliated protozoa that may act as commensals or pathogens of fishes and crustaceans. In the present study, four “ophrys- taxa” scuticociliates, i.e., Paramesanophrys typica gen. et sp. nov., Mesanophrys carcini (Grolière & Léglise, 1977) Small & Lynn in Aescht, 2001, Metanophrys sinensis Song & Wilbert, 2000, and Metanophrys similis Song et al., 2002, were collected from Chinese coastal waters or mariculture ponds and investigated. Paramesanophrys gen. nov. is assigned to the family Orchitophryidae and differs from its other genera mainly by the position of the paroral membrane relative to membranelle 1–3, i.e., the membrane extends anteriorly to the posterior end of membranelle 3. The type species P. typica gen. et sp. nov., is defined by an elongated body with the posterior end depressed where the caudal cilium is located; 20 or 21 somatic kineties; double-rowed membranelle 1 with eight to ten basal bodies in each kinety; irregularly multi-rowed membranelle 2 and membranelle 3; scutica comprising c. seven or eight kinetosome pairs; a single macronuclear nodule; and marine habitat. The redescription of the three previously known species can be summarized as follows: 1) improved diagnosis is provided for Metanophrys sinensis Song & Wilbert, 2000 based on the original description and the present study; 2) some population-dependent characteristics of our new Mesanophrys carcini isolate are presented; 3) Metanophrys similis, collected from the South China Sea, resembles the original Qingdao population.
