Characters
Females are short and moderately deep, with a branched hyoid barbel. Head has short, blunt frontal spines over eyes and well-developed sphenotic spines behind eyes. Teeth in jaws are strong, with longest 10% to 15% of SL, and in two or three series. Hyoid barbel is divided near base into three unpaired main branches and two bifurcated main branches, and ranges from 85% to 115% of SL. Anterior main branch has proximal pair of side branches. Anterior bifurcated branches bear series of side branches. Intermediary main branch is bifurcated and bifurcations are of nearly equal length. Posterior branch is simple. Each of three main unpaired branches has single series of simple side branches. All branches have one or several photophores near tip but lack filaments. Preoperculum is angular and has strong horizontal spine. Pectoral fin has 14 to 19 rays. Illicium is on snout and is short, 20% to 30% of SL. Illicial pterygiophore is concealed or slightly protruding. Esca is large and has single distal appendage of about 10% of SL, with short side branches. Second dorsal fin has 3 rays, anal fin has 3 rays, and caudal fin has 9 rays. Free-living males have short, blunt sphenotic spines that do not penetrate skin. Upper denticular bone has three to six denticles, and lower denticular bone has single median denticle and four to seven lateral denticles on each side.
