Etymology Not stated, but probably from Greek mythology. Nicon was a member of the Telchines (or Telkhines), said to be the original inhabitants of the Island of Rhodes, and according to some sources were the descendents of Thalassa and Pontus, being described as marine beings by Eusthathius. Their mythology is confused, but they appear to have been considered as mostly male entities. See https://pantheon.org/articles/t/telchines.html. Kinberg (1865) created a masculine adjectival name for what became the type species (pictus), another masculine adjectival name (tahitanus), and a feminine adjectival name (maculata from the feminine noun 'macula' meaning spot), plus another three names which were nouns in apposition.

Taxonomy de León-González & Trovant (2013) state: "Some important characteristics were not included by Pettibone (1971) because at that time she recognized N. maculata as the only member of the genus." This statement is incorrect, because Nicon aestuariensis also remained valid and is in Pettibone's genus key. Five other nominal species could not be assigned elsewhere by Pettibone (as indeterminable or doubtfully in Nicon), so their status was uncertain. One of these was Nicon abyssalis, subsequently regarded as valid by de León-González & Trovant (2013:73). Also N. ehlersi and N. benhami were recognisable from types or descriptions as subjective synonyms of N. maculata. Another, Nicon pictus, designated type of the genus by Hartman (1948:57) as first reviser) was deemed indeterminable by Pettibone (1971:49, but this opinion does not alter its type species status (see Type Designation note).

Diagnosis Original diagnosis by Kinberg (1865: 178): ''Papillae pharyngis desideratae, partes laterales segmentorum aequales; branchiae triangulares; setae verutae acutae et falcigerae.'' [details]Etymology Not stated, but probably from Greek mythology. Nicon was a member of the Telchines (or Telkhines), said to be the original inhabitants of the Island of Rhodes, and according to some sources were the descendents of Thalassa and Pontus, being described as marine beings by Eusthathius. Their mythology is confused, but they appear to have been considered as mostly male entities. See https://pantheon.org/articles/t/telchines.html. Kinberg (1865) created a masculine adjectival name for what became the type species (pictus), another masculine adjectival name (tahitanus), and a feminine adjectival name (maculata from the feminine noun 'macula' meaning spot), plus another three names which were nouns in apposition. [details]
Grammatical gender Ambiguous but probably masculine. Some modern-times taxonomists have adopted the gender of feminine as stated by Pettibone (1971: 7), possibly because Nicon maculata was given a feminine suffix by Kinberg. However, if the name came from Nicon as one of the Telchines in Greek Mythology, then the genus should more probably be masculine, as Telchines were apparently male entities (although also a family of beings). Kinberg also named Nicon pictus (masculine) and Nicon tahitanus (assumed masculine). Kinberg's namings created uncertainty. Nicon salinus Hernández-Alcántara & Dávila-Jiménez, 2025 is the latest new name, with the genus regarded as masculine and Nicon maculata Kinberg changed to N. maculatus without commentary on the issue. [details]
Taxonomy de León-González & Trovant (2013) state: "Some important characteristics were not included by Pettibone (1971) because at that time she recognized N. maculata as the only member of the genus." This statement is incorrect, because Nicon aestuariensis also remained valid and is in Pettibone's genus key. Five other nominal species could not be assigned elsewhere by Pettibone (as indeterminable or doubtfully in Nicon), so their status was uncertain. One of these was Nicon abyssalis, subsequently regarded as valid by de León-González & Trovant (2013:73). Also N. ehlersi and N. benhami were recognisable from types or descriptions as subjective synonyms of N. maculata. Another, Nicon pictus, designated type of the genus by Hartman (1948:57) as first reviser) was deemed indeterminable by Pettibone (1971:49, but this opinion does not alter its type species status (see Type Designation note). [details]
Type designation Contrary to the usages of Pettibone (1971), Hutchings & Reid (1990:73) and de León-González & Trovant (2013), Nicon maculata is not the type of Nicon. Nicon pictus remains the Nicon type, regardless of whether it can still be defined now from re-examination of its syntype material. Kinberg (1866:178) included six new species in Nicon, of which N. pictus from Brazil was first mentioned, but did not name a type. Hartman (1948 & 1958) duly designated N. pictus as type species (because it was first in page priority), and described the four syntypes. Pettibone (1971:7) supplanted that nominal species as type in favour of N. maculata, but later authors cannot change prior acts in such a way because of the obvious need to maintain nomenclatural stability. This late second designation is thus invalid under the ICZN Code (Art 69.1 "... no later designation [subsequent to first author to designate] is valid"). [details]
