From editor or global species database
Type species Schneider (1868) described both Polygordius lacteus and P. purpureus in the same article, so the type could be either. Hartman Catalogue treated P. lacteus as type, probably because of page priority (this is not part of the 4thEd Code) which can be regarded as a subsequent designation. P. purpureus has since been moved to Megadrilus. [details]

Etymology Schneider (1868) states he first identified his worms as belonging to Ramphogordius Rathke, 1843, a nemertean genus (in an earlier work?), but realised they were new and used Polygordius instead. The 'gordius' presumably was derived from their twisting or knotted body contortions. The genus has been treated universally as masculine when given adjectival epithets (excludes nouns with adjectival suffixes). [details]
