Aporodoris
Aporodoris is a genus of sea slugs, dorid nudibranch, shell-less marine gastropod molluscs in the family Discorididae.
Taxonomic status
Valdés & Gosliner the valid name of the clade it belongs to, knowing that millegrana is the type species of the genus name Aporodoris von lhering 1886, by original designation. Bergh re-allocated millegrana to Archidoris and then to Thordisa with no explanation. Von lhering created a new generic name for millegrana, Aporodoris. The genus name Aporodoris was then used to describe several new species: Aporodoris rubra Bergh, 1905; Aporodoris risbeci Marcus and Marcus, 1967; and Aporodoris merria Burn, 1973. Thompson and Brown decided to re-allocate millegrana to Discodoris. Then, more recently, Valdes and Gosliner rightly argued that Aporodoris von lhering, 1886, and Taringa Marcus, 1955, are two synonyms, and that millegrana belongs to Taringa species.The next question is: Which name should we use for that clade, Taringa or Aporodoris? The older name, Aporodoris, should have priority over the younger name, Taringa. Valdes and Gosliner argued that in this case, however, the ICZN Article 23.9 applies and that the younger name should be regarded as valid. However, Article 23.9 actually does not apply here. According to Article 23.9, prevailing usage can be maintained only if two conditions are met, one of which is that the senior synonym must not have been used as a valid name after 1899. Although Valdes and Gosliner thought that Aporodoris had not been used as a valid name since 1899, three new species names were created in Aporodoris since 1899, and several authors used the binomial Aporodoris millegrana as valid. Therefore Aporodoris is a valid name, regardless of whether Taringa has been widely used or not.
In addition, but not noted by Dayrat, the combination Aporodoris millegrana was treated as the valid combination for this species between 1910 and 1981 in listings of the British molluscan fauna
However, according to of the International Code of Zoological Nomenclature, this action stands and Taringa should be used as the valid name until such time as the Commission rules otherwise.
