ABSTRACT
Collecting reef-fish specimens using a manned submersible diving to 300 m off Curaçao, southern Caribbean, is resulting in the discovery of numerous new fish species. The new Liopropoma sea bass described here differs from other western Atlantic members of the genus in having VIII, 13 dorsal-fin rays; a moderately indented dorsal-fin margin; a yellow-orange stripe along the entire upper lip; a series of approximately 13 white, chevron-shaped markings on the ventral portion of the trunk; and a reddish-black blotch on the tip of the lower caudal-fin lobe. The new species, with predominantly yellow body and fins, closely resembles the other two "golden basses" found together with it at Curaçao: L. aberrans and L. olneyi. It also shares morphological features with the other western Atlantic liopropomin genus, Bathyanthias. Preliminary phylogenetic data suggest that western Atlantic liopropomins, including Bathyanthias, are monophyletic with respect to Indo-Pacific Liopropoma, and that Bathyanthias is nested within Liopropoma, indicating a need for further study of the generic limits of Liopropoma. The phylogenetic data also suggest that western Atlantic liopropomins comprise three monophyletic clades that have overlapping depth distributions but different depth maxima (3-135 m, 30-150 m, 133-411 m). The new species has the deepest depth range (182-241 m) of any known western Atlantic Liopropoma species. Both allopatric and depth-mediated ecological speciation may have contributed to the evolution of western Atlantic Liopropomini.

Mentions: A combination of morphological and genetic differences supports the recognition of Liopropoma santi as a valid new species of Liopropoma. Liopropoma santi inhabits depths of 182-241 m off Curaçao, making it the deepest known Liopropoma species in the western Atlantic (Fig. 7). The shallower portion of its depth range overlaps the deeper portion of the depth range of Liopropoma olneyi (133–193 m), but with the exception of Robins’ (1967) specimen of Liopropoma aberrans from the Bahamas (229 m), no other western Atlantic Liopropoma species occur within the depth range of Liopropoma santi. A preliminary phylogeny of western Atlantic Liopropoma based on parsimony analysis of the COI data is shown in Figure 8. In that phylogeny, the three species that inhabit depths of 3–135 m (Liopropoma rubre, Liopropoma carmabi, and Liopropoma mowbrayi) form a monophyletic group that is sister to a clade comprising two species that inhabit depths of 30–150 m (Liopropoma eukrines and Liopropoma aberrans from Curaçao). Those clades combined are sister to a clade comprising the deepest western Atlantic Liopropoma (Liopropoma olneyi and Liopropoma santi, 133–241 m) plus two species of the genus Bathyanthias (Bathyanthias mexicanus[Schultz 1958] and a putative new species from Panama) that were collected at 143–259 m. Two additional species of Bathyanthias, Bathyanthias atlanticus [Schultz 1958] and Bathyanthias cubensis (not available for inclusion in the molecular phylogenetic analysis), are known from 82–411 m, and the depth range of non-Curacao Liopropoma aberrans (also not available for inclusion in the phylogenetic analysis) is 89–230 m (Robins 1967, Ocean Biogeographic Information System [OBIS] - http://www.iobis.org/, Fishnet 2 - http://www.fishnet2.net/).

ABSTRACT
Collecting reef-fish specimens using a manned submersible diving to 300 m off Curaçao, southern Caribbean, is resulting in the discovery of numerous new fish species. The new Liopropoma sea bass described here differs from other western Atlantic members of the genus in having VIII, 13 dorsal-fin rays; a moderately indented dorsal-fin margin; a yellow-orange stripe along the entire upper lip; a series of approximately 13 white, chevron-shaped markings on the ventral portion of the trunk; and a reddish-black blotch on the tip of the lower caudal-fin lobe. The new species, with predominantly yellow body and fins, closely resembles the other two "golden basses" found together with it at Curaçao: L. aberrans and L. olneyi. It also shares morphological features with the other western Atlantic liopropomin genus, Bathyanthias. Preliminary phylogenetic data suggest that western Atlantic liopropomins, including Bathyanthias, are monophyletic with respect to Indo-Pacific Liopropoma, and that Bathyanthias is nested within Liopropoma, indicating a need for further study of the generic limits of Liopropoma. The phylogenetic data also suggest that western Atlantic liopropomins comprise three monophyletic clades that have overlapping depth distributions but different depth maxima (3-135 m, 30-150 m, 133-411 m). The new species has the deepest depth range (182-241 m) of any known western Atlantic Liopropoma species. Both allopatric and depth-mediated ecological speciation may have contributed to the evolution of western Atlantic Liopropomini.
