Concavus is a genus of barnacles. [4]
As of 2021 [update], WoRMS recognizes the following two species: [4]
The genus was circumscribed by William A. Newman in 1982. His original list of subgenera and species for the genus was the following: [3]
Newman noted there were multiple fossil taxa in this genus, but didn't classify any except for the type species †C. concavus. [3]
In 1992, Victor A. Zullo revised the genus. He created a new subfamily, Concavinae, with Tamiosoma Conrad, 1856 (the senior synonym of Menesiniella according to Zullo [b]), Arossia and Concavus among its genera. With his revision, Concavus only consists of the two species C. concavus and C. crassostricola. [1]
This genus is known in the fossil records from the Oligocene to the Quaternary (age range: from 28.4 to 0.012 million years ago). Fossils are found in the marine strata of United States, Italy, Mexico, Morocco, Algeria, France, Haiti, Madagascar, Panama, Colombia and Slovenia. [7]
