Trichite features contribute to the revision of the genus Strombidium (Alveolata, Ciliophora, Spirotricha).

ABSTRACT: Strombidium is a species-rich genus of oligotrichid ciliates mainly inhabiting the marine pelagial. In molecular phylogenies, the genus emerged as non-monophyletic, and cladistic analyses suggest that it is largely characterized by plesiomorphies. A reliable split of the genus and the establishment of new genera necessitate, however, support by novel morphological and/or ultrastructural features. In the present study, the arrangement and ultrastructure of trichites are proposed as taxonomically relevant characters. Strombidium biarmatum Agatha et al., 2005 differs in the trichite pattern from the type species Strombidium sulcatum and most congeners. Aside from the trichites inserting anteriorly to the girdle kinety and generating the typical funnel-shaped complex in the posterior cell port
