背面の脊椎 (合計) : 13 - 14; 背鰭 (合計) : 11 - 13; 肛門の骨: 3; 臀鰭: 9 - 12. Diagnosis: A very small slender species with a wide mouth with broad lips bearing numerous teeth (Ref. 118638). Mature males have dark-edged dorsal and anal fins, iridescent blue-white spots on flanks, white lips, and a spotted caudal fin edged in pink; male breeding dress shows geographic variation, with some populations having yellow bellies and throats, while others are white (Ref. 118638).
