Dorsal and anal fins yellowish red. One paler darkish, vertical band from occiput to base of pectoral fin.” Katayama (1984:138) mentioned that this species occurs on the Kyushu-Palau Ridge and in the Hawaiian Islands, that its body is reddish -yellow, and that it reaches 150 mm SL. Masuda et al. (1984, plate 124, figures G & H) published color photographs of a 130-mm male and a 120-mm female.

Senou (2002:733) provided a brief account that includes diagnostic data and the following comments on bathymetric and geographic ranges: “From 300 to 500m depth. Kyushu-Palau Ridge; Hawaiian Isls.”

The other (BPBM 19651, 122 mm SL) has a very pale pink wash over head and body; fins with much white; considerable dull reddish pigment on many interradial membranes of dorsal fin; distal ends of both lobes of caudal fin dull reddish.

that he examined in preparing the original description “have the pelvic fin well produced (with the medial branch of the first pelvic soft ray reaching anterior part of base of anal fin or beyond), whereas in the other specimens... the pelvic fin, although usually produced, falls short of the anal fin.” He tried to determine the sex of several individuals, but, because of the relatively small size of the specimens, was only partly successful. Nevertheless, he suggested that the well-produced pelvic fin is a male characteristic -as it is in

). Tameka (1982:372) observed that: “First soft ray of pelvic fin elongated in male, reaching backward beyond base of anal fin or to caudal fin. Pelvic fin of female not elongated.” In the specimens reported by Anderson (1970), the pelvic fin varies in length from ca. 22->54% SL. In 16 of the additional specimens (79-141 mm SL) examined, the pelvic fin is appreciably elongated, ranging in length from ca. 42->80 % SL. Based on gross examination of the gonads, two of those specimens (120 & 128 mm SL) are males.

caught off Lombok, Indonesia, are appreciably larger than those reported in the original description (120 & 128 mm SL vs. ca. 42- 86 mm SL). In a number of morphometric characters (e.g., depth of body) those two Lombok specimens exhibit ranges that do not overlap or overlap only slightly with the ranges of the other material studied. Comparisons of the ranges for those characters for shallowbodied vs. deep-bodied morphs are presented in Table 7. The two large specimens collected off Lombok are males, based on gross examination of gonads and lengths of pelvic fins and caudal-fin lobes (see above). We attribute the differences seen in Table 7 to allometric growth and sexual dimorphism.
