More new deep-reef basslets (Teleostei, Grammatidae, ), with updates on the eco-evolutionary relationships within the genus.

Two new basslets are described, and , captured during submersible diving to 300 m depth off Curaçao, southern Caribbean. Superficially resembling in having 11-12 bars of pigment on the trunk, is distinct from in having a stripe of blue-white pigment along the dorsal midline of the head (vs. a cap of yellow pigment), in patterns of pigment on the median fins, and in having 8-10 gill rakers on the lower limb of the first arch (vs. 11-12). is distinct from all congeners in having seven or eight dark bars of pigment on the trunk and broad, irregular, whitish blue markings on the dorsal portion of the head. The new species are genetically distinct from one another and from seven other species for which genetic data are available. A phylogenetic hypothesis derived from mitochondrial and nuclear genes suggests that the new species belong to a clade that also comprises and Collectively those four species are the deepest-living members of the genus, occurring at depths predominantly below 140 m. This study thus provides further evidence of eco-evolutionary correlations between depth and phylogeny in Caribbean reef fishes. Tropical deep reefs are globally underexplored ecosystems, and further investigation of Caribbean deep reefs undoubtedly will provide samples of species for which no genetic material currently exists and reveal more cryptic species diversity in the genus.
