| contents | Morpho-molecular taxonomy and systematics of Suctoria (Ciliophora, Phyllopharyngea), with descriptions of four species from wetland habitats in China. Ma, Mingzhen Wang, Yiwen Song, Wen Ma, Honggang Wang, Ya Al-Rasheid, Khaled A S Song, Weibo Warren, Alan Wang, Zhe Li, Lifang Chen, Xiangrui China Phylogeny Wetlands Ciliophora Species Specificity DNA, Protozoan DNA, Ribosomal RNA, Ribosomal, 18S The subclass Suctoria is considered one of the most distinctive groups among ciliates due to the absence of cilia in the trophont stage. Biological control using suctorians may promote sustainable aquaculture while mitigating risks associated with pesticide use and drug residues. In this study, four species from wetland habitats in China were investigated using morphological and molecular methods. These species include one new species, Metacineta perimystacina n. sp., and three poorly known species: Spelaeophrya polypoides, Trichophrya epistylidis, and Discophrya robusta. Metacineta perimystacina is distinguished by a stalk comprising about 70% of the total body length and by six slits on the lorica. Small subunit rDNA sequences were obtained for all four species to determine their systematic positions. Phylogenetic analyses indicate that the orders Exogenida and Endogenida are polyphyletic, and they further suggest that the semicircumvaginative reproductive mode may represent a transitional state between the exogenous and endogenous types. Spelaeophrya polypoides exhibits a distinctive mode of budding known as vermigemmy, characterized by the lateral production of a vermiform, unciliated swarmer. Its distinct phylogenetic position highlights the uniqueness of this lineage and suggests that it may represent a new order. Finally, some species may show substrate/host specificity, providing new insights into ecological management and pathogen control. |
