Classification Pleijel (1991), in a work in which he catalogued all phyllodocids, placed Mysta and Hypereteone as synonyms of Eteone because in the morphological data analyzed there was a "polytomy with Eteone, Hypereteone and Mysta which could not be resolved in any trees due to lack of characters separating these genera". The characters of this group are: "presence of four antennae, a nuchal papilla, two pairs of tentacular cirri on the first visible segment (segment 2), and the absence of tentacular or dorsal cirri on segment 3." Earlier Wilson(1988) had distinguished Mysta from Eteone on the proboscis papillae patterns. The Mysta proboscis has 2 lateral longitudinal rows of foliose papillae and a dorsal band of very small denticulate papillae, whereas Eteone lacked longitudinal papillae rows. Without comment Kato, Pleijel & Mawatare (2001) retreated from Pleijel's earlier synonymy of Mysta, listed the Mysta species they considered valid, and named a new Mysta species. There appears to have been no change in the valid status of Mysta since then. [details]
Diagnosis Original diagnosis by Malmgren (1865: 100-101): "Corpus lineare antice posticeque paullum attenuatum, subdepressum. Lobus cephalicus e basi lata angustatus. Tentacula 4 brevia, subulata, in apice truncato lobi cephalici affixa, bina utrinque alter super alterum. Oculi duo conspicui, mediocres. Cirri tentaculares duo inaequales, subulati, in segmento primo affixi. Proboscis exserta, longa, subcylindrica, antrorsum incrassata, versus apicem papillis numerosis, ovato-fusiformibus brevibus, utrinque in ordine longitudinali dispositis, ornata. Setae capillares compositae, articulo terminali longe attenuato leviter curvato, margine concavo subtilissime denticulato. Appendix superior mediocris lamellaeformis, subverticalis, extrorsum porrecta. Appendix inferior compressa ovalis. Pars setigera pedis apice rotundato leviter inciso. Cirri duo anales." [details]
Etymology Not stated, uncertain. Maybe from the Latin word mysta or mystes, derived from the Greek and meaning in ancient and Late Latin 'one initiated in mysteries, or secret doctrines'. [details]
