Redescription of the dasydytid gastrotrich Haltidytes ooëides (Brunson, 1950) based on type material

Abstract

The semi-pelagic gastrotrich species Haltidytes ooëides (Brunson, 1950) is redescribed based on original type material deposited at the Smithsonian National Museum of Natural History. Herein we present a new diagnosis and figures of the species, detailing the insertion position of the lateral spines, misinterpreted in the original description. Furthermore, we reassess the taxonomic key for the genus Haltidytes Remane, 1936 based on our new findings.
