| 内容記述 | Lethrinus longirostris Playfair, 1867, previously regarded as a junior synonym of Lethrinus olivaceus Valenciennes, 1830, is redescribed as a valid species on the basis of 65 specimens (123.5– 697.2 mm standard length: SL) from southern Japan. The two species are similar to each other morphologically in sharing six transverse scale rows above the lateral line, snout length (excluding the lip) 0.6–0.8 times in cheek height, and body depth 2.9–3.5 times in SL. However, L. longirostris can be distinguished from L. olivaceus by having a lower count of the gill rakers on the lower limb at the first gill arch [5–7 (modally 6) vs. 6–9 (8) in L. olivaceus], the sum of the above-mentioned rakers on both sides of the body [11–14 (12) vs. 14–18 (16)], the anterodorsal snout red in specimens over ca. 450 mm SL (vs. orangish yellow), red transverse bands on the snout and interorbital regions (one band anterior to eye, one band above eye) in specimens over ca. 500 mm SL (vs. orangish yellow bands), poorly defined red blotches/ bands on the head below the eye and the upper opercle in specimens over ca. 240 mm SL, red blotches on the upper opercle extending below onto the middle of the opercle with growth (vs. no red blotches on opercle throughout life), and the soft-rayed portion of the dorsal fin dense black in preserved specimens over ca. 440 mm SL (vs. pale gray). Analysis of the mitochondrial cytochrome oxidase I (COI) gene in both species showed them to be separated by 7.7–9.3% p-distance. In addition to L. longi-rostris, the following four nominal species have previously been synonymized with L. olivaceus: viz., Lethrinus rostratus Valenciennes, 1830 (type locality: Java, Indonesia; RMNH D443, holotype, size unknown), Lethrinus waigiensis Valenciennes, 1830 (Waigeo, Indonesia; MNHN 0000-9065, lectotype, 104 mm SL), Lethrinus xanthopterus Valenciennes, 1830 (Caroline Islands; no types known), and Lethrinus rostratus specificus Borodin, 1932 (Bora Bora, Society Islands; VMM 790, 2 syntypes, 400, 496 mm SL). Because coloration of the available type specimens was faded owing to a long-term preservation, the gill raker counts were examined in this study to resolve their taxonomic status. The sum of the gill rakers on the lower limbs at the first gill arches on the both sides of the body of L. rostratus specificus was 16; thus it was regarded as a junior synonym of L. olivaceus. No coloration and gill-raker data were obtained from L. xanthopterus (no types known), L. rostratus (stuffed specimen), and L. waigiensis (right side gill arch was cut from middle and number of rakers on lower limb is thus not available); the three nominal species therefore were herein regarded as nomen dubium. Lethrinus longirostris and L. olivaceus are almost sympatrically distributed in the Indo-Pacific Ocean: L. longirostris is recorded from the Red Sea and Tanzania east to French Poly-nesia, and from Japan south to the Coral Sea; and L. olivaceus is from South Africa east to French Polynesia, and Japan south to Indonesia. | |||||
