Females: bulb of esca with large, oblong, internally silvery, distal prolongation (as long as diameter of bulb) with a terminal cluster of about 7 branched filaments inside a circle of 7 shorter filaments; one each side of bulb at base of distal prolongation a small, distally-fringed lobe; posterior appendage of esca compressed with fringed edge. Barbel with undivided and slightly tapering branches, length of each about 12% SL; at base of a similar, but somewhat distinct, shorter, distal prolongation of the stem, each of these three filamentous endings bearing a few internal photophores. Pointed frontal spines present. Males: pointed sphenotic spines, and a distinct, but weak concentration of subdermal pigment on caudal peduncle (Ref. 42949). |
