Etymology Zelinka (1928, pp. 273-274): "Ich benenne sie zum Gedenken Ggreeffs, der unter den Beobachtern der Echinoderen sich durch feine und relativ verläßliche Beobachtung auszeichnete, als Centropsis greeffii." = I name [the larva] in memory of Greeff, who stands out among the observers of echinoders [= kinorhynchs] by fine and relatively reliable observations, as Centropsis greeffii. - The name Greeff was Latinized to Greeffius with its genetive case Greeffii. [details]Spelling The species name E. greeffii represents the genitive case of the Latinized name Greeffi derived from the person's name Greeff. This is in accordance with ICZN (Articles 31.1.2. and 31.1.3.). The name E. greeffii has been used consistently ever since, so this original writing with -ii has to be preserved (ICZN, Article 33.4. Use of -i for -ii and vice versa, and other alternative spellings, in subsequent spellings of species-group names.). [details]
