Description
Summary:A new species of Lipogramma is described from submersible collections at 122–165 m depth off the coast of Roatan, Honduras, in the western Caribbean. The new species is distinguished from all other species in the genus by its bright blue coloration on the head, nape, and dorsal portion of the trunk beneath the spinous dorsal fin, a prominent round black blotch below the origin of the spinous dorsal fin, and a high number of gill rakers. A molecular phylogeny based on mitochondrial and nuclear genes shows that the new species belongs to a clade containing L. levinsoni, L. regia, and L. anabantoides. At Roatan, submersible observations of this and other Lipogramma species indicate clear, interspecific habitat partitioning by depth and substrate.
