Abstract
Sciadonus alphacrucis Melo, Gomes, M & oslash;ller & Nielsen, 2022 is a rare deep-sea species, previously known from only two specimens collected off S & atilde;o Paulo State, southeastern Brazil, in the western South Atlantic. Herein, we report a new specimen of S. alphacrucis collected on the continental slope off Santa Catarina State, southern Brazil, thereby extending its known distribution by 420 km. Additionally, we provide the new meristic and morphometric data, the molecular identification using sequences of the cytochrome c oxidase subunit I (COI), an updated distribution map, and a discussion of troglomorphic traits.
