Abstract: | The juveniles of Kyphosus vaigiensis (Quoy and Gaimard 1825), collected from the Indian Ocean and Japanese waters, are described with some ontogenetic morphological changes based on
six specimens having 14 dorsal and 13 anal fin soft rays, 56–62 scales in a longitudinal row along the midbody, and 30–32
gill-rakers on the first gill-arch. The juveniles of K. vaigiensis smaller than ca. 42 mm in standard length (SL) have the proximal parts of the dorsal and anal fin soft-rayed portions covered
with small scales, and the single outer row of the upper jaw teeth consisting of incisor-like and conically pointed teeth,
the former with polycuspid tips differing from the specimens greater than ca. 68 mm SL. The holotype of Cantharus lineolatus Valenciennes 1830, 41.5 mm SL, was included here in the juveniles as K. vaigiensis. Therefore, K. vaigiensis is recognized as a senior synonym of C. lineolatus. |
