Morphological redescriptions and neotypification of two poorly known tintinnine ciliates (Alveolata, Ciliophora, Tintinnina), with a phylogenetic investigation based on SSU rRNA gene sequences

Abstract

The GenBank accession numbers for the SSU rRNA gene sequences of Codonellopsis mobilis and Tintinnopsis chinglanensis are MK799838 and MK799839, respectively. This article is registered in ZooBank under: urn: lsid: zoobank. org: pub: 9F6D628B-4C3C-4910-820D-C1E2485E6D27. One supplementary table is available with the online version of this article.

Three Redescriptions in Tintinnopsis (Protista ：Ciliophora: Tintinnina) from Coastal Waters of China, with Cytology and Phylogenetic Analyses Based on Ribosomal RNA Genes

“…Thus, the current lorica-based taxonomy does not allow estimating tintinnine diversity accurately, and it does not provide a natural classification. Accordingly, several studies have incorporated more informative characters, namely, cytological and/ or molecular data, in tintinnine systematics (e.g., [27] [36]). Still, cell characters and DNA sequences are only known for about 3% and 10% of the described tintinnine morphospecies, respectively (e.g., [22] [37]), and considerable efforts are needed to increase the availability of these types of information.…”

“…Out of the about 140 Tintinnopsis-like morphospecies [19] [20] [21], about 60 have been recorded in China seas (e.g. [21] [40] [41] [42] [43] [44]), but only a few count with ciliature and/or sequence data [34] [45] [46] [36] [47] [48]. Overall, Tintinnopsis will need subdivision once its type, T. beroidea, and other species are studied with modern methods [22] [38] [39].…”
