AI Article Synopsis
- The study examines the morphology, particularly the ciliary patterns, of two cyrtophorid ciliates, Aegyria apoliva sp. nov. and Trithigmostoma cucullulus, found in coastal and estuarine waters of China.
- Aegyria apoliva sp. nov. is detailed with specific morphological features including size, pigmentation, and structures like somatic kineties and contractile vacuoles, while Trithigmostoma cucullulus aligns with earlier findings and only receives a brief description.
- Phylogenetic analysis using small-subunit rRNA gene sequences confirms the classification of Aegyria apoliva as a new species and supports the grouping of both genera.
Article Abstract
The morphology, including the ciliary pattern, of two cyrtophorid ciliates, namely Aegyria apoliva sp. nov. and Trithigmostoma cucullulus (Müller, 1786) Jankowski, 1967, were investigated. They were isolated from coastal water off Qingdao and from an estuarine habitat in south China, respectively. Aegyria apoliva sp. nov. is characterized as following: body size 100-120 × 50-70 μm in vivo with dark pigment spot on anterior left part of cell; 48-69 somatic kineties; one preoral and four or five circumoral kineties; 9-13 transpodial segments; 26-40 nematodesmal rods; 6-10 contractile vacuoles. The Guangzhou population of Trithigmostoma cucullulus corresponds well with previously described populations, therefore only a brief morphological description is presented. Phylogenetic analysis based on small-subunit rRNA gene sequences data supports the establishment of the new species as well as the monophyly of both genera.
