“…Jung et al. () speculated that Holostichides is not monophyletic and can be classified into three types based on the patterns of undulating membranes, frontoterminal cirri and pharynx. However, the molecular data of H. chardezi and H. dumonti were unavailable to prove the assumption.…”

“…Established by Foissner () and assigned to the family Bakuellidae, Holostichides can be separated from other urostyloids by having the following features: three distinct frontal cirri, midventral rows present, transverse and pretransverse cirri lacking, one left and one right marginal row, caudal cirri present and four to six dorsal kineties. To date, five species have been reported: H. chardezi Foissner, (type species); H. dumonti Foissner, ; H. heterotypicus Kim et al., ; H. terrae Jung et al., ; and H. typicus (Song and Wilbert, ) Eigner, 1994. However, morphogenetic data is available for H. chardezi (partly known), H. heterotypicus and H. typicus, and gene sequences of small subunit rDNA (SSU rDNA) are available for only H. heterotypicus and H. terrae (Jung et al.…”

Morphogenesis of the soil hypotrich ciliate, Holostichides chardezi Foissner, 1987, collected from southeastern China, was investigated using the protargol staining method. The main morphogenetic events follow a similar process with that of its congeners. Phylogenetic analyses based on the SSU rDNA sequence data indicate that Holostichides is nonmonophyletic; H. chardezi, the type species of Holostichides, clusters with H. heterotypicus, while H. terrae is distinctly separate from these species. H. terrae can be distinguished from H. chardezi (type species of Holostichides) and H. heterotypicus by undulating membranes relatively long and distinctly curved (vs. relatively short and straight), pharynx with (vs. without) rod‐shaped structure, and two (vs. more than two) frontoterminal cirri. Therefore, a new genus, Anteholostichides nov. gen., has been proposed for H. terrae. Further, the diagnosis of the genus Holostichides is improved.
