摘要：

This species is distinguished by a combination of the following characters: possession of hooks in all fins of males, teeth not expanded distally, two or three maxillary teeth, 37-39 perforated scales in the lateral series, 25-30 branched anal-fin rays, and anal-fin origin located before a vertical through last dorsal-fin ray insertions.
