Abstract
The morphology, morphogenesis, and molecular phylogeny of a new ciliate, Aspidisca koreana n. sp., discovered in the eastern coast of South Korea, were investigated. The morphological description is based on the observation of living cells, 4′-6-diamidino-2-phenylindole (DAPI) and silver-stained specimens (e.g., protargol, silver nitrate), and scanning electron micrographs. The new species is characterized by having a small body size (17–25 × 15–18 μm in vivo), a distinct peristomial spur on the posterior portion of left margin, seven frontoventral cirri in “polystyla-arrangement”, and the arrangement of the anterior portion of adoral zone of membranelles, i.e., anteriormost membranelle is distinctly separated from the other three membranelles. The morphogenesis follows the typical pattern of this genus. Phylogenetic analyses, using the 18S rDNA sequence, also support the establishment of a new species.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
