First record of the genus Carminodoris Bergh, 1889 (Gastropoda: Opisthobranchia: Nudibranchia: Doridoidea: Discodorididae) in the Colombian Caribbean

In the Atlantic Ocean there are only two records of Nudibranchs belonging to the genus Carminodoris Bergh, 1889 (Discodorididae). This work describes and illustrates the first record of a Nudibranchs belonging to this genus in the Colombian Caribbean, in a sample collected on Isla San Martin de Pajarales, islas del Rosario, Cartagena, Colombia. The morphological and anatomical attributes of the studied specimen were compared with those reported for the Atlantic (Carminodoris hansrosaorum and C. madibenthos), and for the Pacific (C. nodulosa, C. grandiflora, C. bramale, C. flammea, C. bifurcata, C. armata and C. estrelyado). The studied sample differs from the other species by its size (74 mm), and distinctive morphological patterns (foot, tubercles, branchial plume, mantle, jaw and radular formula). This is the first report of this genus in the southwestern Caribbean and it might be a new species, yet to be confirmed, with additional anatomical and molecular studies.
