Etymology The genus name was derived from Greek εχίνος echinos, hedgehog, and Greek deres, neck, a common suffix of cyclorhagid genera, and referred to the spiny scalids of the introvert, which Dujardin (1851) regarded as neck (Higgins 1971). Echinoderes represents the first described genus of the Kinorhyncha. [details]
