ABSTRACT
The relationships of the mainly free living, obligately anaerobic ciliated protists belonging to order Metopida continue to be clarified and now comprise three families Metopidae, Tropidoatractidae, and Apometopidae. The most species-rich genus of the Metopidae, Metopus has undergone considerable subdivision into new genera in recent years as more taxa are characterized by modern morphologic and molecular methods. The genus, Castula, was established to accommodate setae-bearing species previously assigned to Metopus C. setosa and C. fusca, and one new species, C. flexibilis. Another new species, C. specialis, has been added since. Here we redescribe another species previously included in Metopus, using morphologic and molecular methods, and transfer it to Castula as C. strelkowi n. comb. (original combination Metopus strelkowi). We also reassess the monotypic genus, Pileometopus, which nests within the strongly supported Castula clade in 18S rRNA gene trees and conclude that it represents a morphologically divergent species of Castula.
