Mexichromis is a genus of colourful sea slugs, dorid nudibranchs, shell-less marine gastropod mollusks in the family Chromodorididae. [2] [3] [4] [5] [6] [7] Current synonymy follows a revision of Chromodorididae which used molecular phylogeny. [8]
A genus is a taxonomic rank used in the biological classification of living and fossil organisms, as well as viruses, in biology. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus.
Sea slug is a common name for some marine invertebrates with varying levels of resemblance to terrestrial slugs. Most creatures known as sea slugs are actually gastropods, i.e. they are sea snails that over evolutionary time have either completely lost their shells, or have seemingly lost their shells due to having a greatly reduced or internal shell. The name "sea slug" is most often applied to nudibranchs, as well as to a paraphyletic set of other marine gastropods without obvious shells.
Nudibranchs are a group of soft-bodied, marine gastropod molluscs which shed their shells after their larval stage. They are noted for their often extraordinary colours and striking forms, and they have been given colourful nicknames to match, such as "clown", "marigold", "splendid", "dancer", and "dragon". Currently, about 3,000 valid species of nudibranchs are known.
The genus Mexichromis is represented in the Eastern Pacific by five species, Mexichromis antonii , Mexichromis amalguae , Mexichromis porterae , Mexichromis tica and Mexichromis tura . In the central Indo-Pacific region there are three groups of species, Mexichromis festiva , Mexichromis katalexis , Mexichromis macropus , Mexichromis mariei and Mexichromis multituberculata , all with compact bodies and large dorsal tubercles, Mexichromis aurora and Mexichromis trilineata which were formerly placed in the genus Pectenodoris because of their radula morphology, plus Mexichromis lemniscata , Mexichromis pusilla , Mexichromis albofimbria , Mexichromis circumflava and Mexichromis similaris with long, narrow bodies, which were formerly placed in the genus Durvilledoris .

The Chromodorididae, or chromodorids, are a taxonomic family of colourful, sea slugs; dorid nudibranchs, marine gastropod mollusks in the superfamily Doridoidea. “Chromodorid nudibranchs are among the most gorgeously coloured of all animals.” The over 360 described species are primarily found in tropical and subtropical waters, as members of coral reef communities, specifically associated with their sponge prey. The chromodorids are the most speciose family of opisthobranchs. They range in size from <10mm to over 30 cm, although most species are approximately 15–30 mm in size.
Chromodoris is a genus of very colourful sea slugs or dorid nudibranchs, marine gastropod molluscs, and the type genus of in the family Chromodorididae. Within the Chromodoris genus, there are currently 101 classified species. Species within Chromodoris are commonly found in tropical and subtropical waters, living as members of reef communities and preying primarily on sponges. A molecular phylogeny of the family Chromodorididae resulted in this genus being restricted to a smaller number of species than formerly, most of which have longitudinal black lines on the mantle. Many former members of Chromodoris were transferred to Goniobranchus
Okenia is a genus of colorful sea slugs, specifically of dorid nudibranchs, marine gastropod mollusks in the family Goniodorididae.
Hypselodoris is a genus of colourful sea slugs or dorid nudibranchs, marine gastropod mollusks in the family Chromodorididae. Modern usage follows a more restricted view of which species belong in this genus so there are numerous genus transfers.
Felimare orsinii is a species of colourful sea slug, a dorid nudibranch in the family Chromodorididae.
Glossodoris is a genus of sea slugs, dorid nudibranchs, shell-less marine gastropod mollusks in the family Chromodorididae.
Durvilledoris was a genus of sea slugs, dorid nudibranchs, shell-less marine gastropod mollusks in the family Chromodorididae. This genus has become a synonym of Mexichromis Bertsch, 1977 Although the type species of this genus was transferred to Mexichromis two species were not reallocated nor mentioned in the text.
