Kinorhyncha

Species of suctorian ciliates on different basibionts of Kinorhyncha View in CoL .

Zelinka (1914) described inadvertently the epibiontic Loricophrya tuba on Kinorhyncha from the Gulf of Trieste, because he mentioned the species's name in connection with identifying morphological characters. A more substantial description, the species name of the basibiont of this epibiont, Pycnophyes communis , and the record of Flectacineta livadiana ? followed in his monograph ( Zelinka 1928). Adrianov and Higgins (1996, fig. 23) labelled two epibionts of Pycophyes parasanjuanensis as “ectocommensal suctorians”, but these specimens represented a species of Cothurnia and not a suctorian. Dovgal et al. (2008) reported Limnoricus ponticus from an unidentified Indian species of Pycnophyes . Together with the new species reported in this article, four acinetid species are now known to settle on pycnophyid Kinorhyncha in European and Indian waters.

Trematosoma husselae sp. nov. was here reported from species of Kinorhyncha, but few other species of Trematosoma were known to settle on meiofauna, viz, T. amphiasci , T. bocqueti , and T. pusilla on Coepepoda, and T. rotunda on Nematoda ( Precht 1935; Guilcher 1950; Allgén 1951; Fernandez-Leborans et al. 2012; Chatterjee et al. 2020, 2022).
