Mexichromis

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]

Distribution

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.
