title: Apotrachelocerca arenicola (Kahl, 1933) n. g., comb. n. (Protozoa, Ciliophora, Trachelocercidae): morphology and phylogeny.
abstract: During faunistic study on psammophilic ciliates along the coast of Qingdao, China, a population of Trachelocerca arenicola Kahl, 1933 was found and then investigated using silver staining and gene sequencing methods. The results indicated that it represented a new genus Apotrachelocerca characterized by uninterrupted circumoral kineties composed of two rows of dikinetids and no brosse or ciliary tuft in the oral cavity. This new genus should be assigned to the family Prototrachelocercidae Foissner, 1996. Based on the small subunit rRNA gene sequence, phylogenetic trees revealed that Apotrachelocerca arenicola occupied a basal position to other trachelocercids.
