Tonicia


Tonicia is a genus of chitons in the subfamily Toniciinae of the family Chitonidae.
The genus was recently restricted to include only 12 New World species, with the more species-rich and exclusively Old World subgenus Lucilina Dall, 1882, being elevated to a separate genus. Of these 12, ten species are found in the eastern Pacific, one in the Magellan province and one in the Caribbean Sea.
However, a study published in 2019 which used molecular systematics to compare the eastern Pacific Tonicia species suggested that there are only 9 extant species in the eastern Pacific.
