Short description
Khóa để định loại | Hình thái học | Sinh trắc học
Tia mềm vây hậu môn: 147 - 165; Động vật có xương sống: 77 - 79. This species is distinguished from its congeners by the following characters: presence of a flat posterior dorsal surface of the basihyal (vs. ridge); with 12 or fewer teeth on pharyngobranchial (vs. 14); a small body cavity usually with less than 14 pre-caudal vertebrae present (vs. 14); without a crown of thorny projections present at border of parietals and supraoccipital (vs. present in patriciae, orthos) (shared with duccis, orinoco, rex, raptor, schotti, sima); with a deep caudal peduncle, 27-42% HL (vs. 15-21% HL) (Ref. 126780).
