The body of metamorphosed females is relatively short and oval to globular, the length and depth of the head about 50% SL. The sphenotics, epiotics, posttemporals, preopercles, anterodorsal margins of the frontals, heads of the palatines, symphysis of the lower jaw, all with well-developed spines. The posteroventral margin of the articulars is notched to form a pair of short spines. The positions, numbers, and relative length of the spines of the head is somewhat variable: the left posttemporal bears only a single spine in one known specimen; in all specimens examined, the 5 or 6 preopercular spines include a dorsal and ventral pair, while the position of one or two median spines varies in relation to that of the pairs. The nostrils are set on low papilla. The lateral-line organs are stalked and unpigmented. The escal bulb is unpigmented and globular or slightly oval in shape, nearly sessile on the blunt tip of the pterygiophore of the illicium. The diameter of the escal bulb is 3.5–4.5% SL. Escal filaments and appendages are absent. The inner wall of the spherical photophore is black except for a relatively narrow distal transparent field. The teeth are slender, recurved, depressi
