Common Name

Yellowbar Basslet

Year Described

Gilmore, 1997

Identification

Dorsal Fin: XII, 9
Anal Fin: III, 8
Pelvic Fin: I, 5
Pectoral Fin: 15
Caudal Rays: 19 (segmented)
Gill Rakers: 3-4 upper, 11-12 lower; 14-16 total
Vertebrae: 10 precaudal, 15 caudal; 25 total
Lateral Scale Rows: 21-25

Body stout with pointed snout. Lateral line absent. Preopercular margin smooth. Pelvic fin extends well past anal fin origin when depressed. Outer procurrent caudal rays thickened (3 ventrally and dorsally). Caudal fin emarginate.

Color

Body tan to straw yellow, with 8-12 darker brown bars on the body that do not extend onto fins. Center of scales are lighter in color. The first band is partial above the upper gill opening, and the darker bands are slightly narrower than the interspaces. The head is plain except for a dark band through the eye edged in white. A pale line runs from the snout to the dorsal fin on the nape, becoming broken on the snout. There is a black ocellus (with white border) on the rear dorsal fin. Dorsal, anal, and caudal fins pale to brilliant blue with yellow spots and wide blue borders. Pelvic fins blue with darker speckles.

Size

Maximum size to 50mm.

Habitat

Deep rock ledges from 200-300m.

Range

Scattered records in the Caribbean Sea: Bahamas, Cuba, Belize and Curacao.

Other Notes

Recent living specimens from Curacao differ slightly from the original description in having fewer brown bars, an obvious eye-band, and brilliant blue on the fins. Genetic data shows deep divergence between two lineages identified as Lipogramma robinsi, and at least one undescribed species exists (Baldwin et al., 2016).
