Strombidium inclinatum n. sp. and a Reassessment of Strombidium sulcatum Claparède and Lachmann (Ciliophora)

Abstract

Strombidium sulcatum is the type species for the genus Strombidium and has been repeatedly referred to over the last 130 yr. However, there are several taxonomic problems associated with it. We discuss why the original description of S. sulcatum lacks resolution to describe a single species. We conclude that: (1) the description of S. sulcatum sensu Fauré‐Fremiet, 1912 be used to diagnose the species; (2) there are ambiguities in several redescriptions of S. sulcatum; and (3) S. sulcatum sensu Lynn et al., 1988 is Strombidium emergens (Leegaard, 1915) Kahl, 1932. From this analysis we present a description for Strombidium inclinatum n. sp. (previously S. sulcatum sensu Fenchel and Jonsson, 1988). Copyright © 1990, Wiley Blackwell. All rights reserved
