Etymology: Opistognathus: Greek, opisthe = behind + Greek, gnathos = jaw (Ref. 45335); to the very elongate upper jaw of the type species of the genus, Opistognathus nigromarginatus (Ref. 128653)adelus: Name from the Greek 'adelos' meaning dim or obscure; refers to the uncertain phylogenetic relationships of this jawfish.

Korte beschrijving Determinatiesleutels | Morfologie | Morfometrie

Dorsale stekels (totaal) : 6; Dorsale zachte stralen (totaal) : 13 - 14; Anale stekels: 3; Anale zachte stralen: 13 - 14; Wervels: 27 - 28. This species is distinguished by the following set of characters: upper jaw is broadly rounded with a large oval-shaped supramaxilla, and maxilla with a flexible lamina posteriorly, extending 1.0-1.2 eye diameters behind posterior margin of orbit; D XI,13-14; dark blotch on posterior angle of jaws, including inner lining of maxilla and adjacent membranes; no ocellus or large dark blotches on dorsal fin; no vomerine teeth (Ref. 85161). Expanded diagnostics: infraorbitals relatively robust, 2nd and 3rd infraorbitals with large sensory canal openings, 3rd infraorbital with no suborbital shelf; A III, 13-14; vertebrae 10+17-18; scale rows in horizontal series about 40-41; gill raker 9+15-16 in adults (except 6+14 in two juveniles, 21.0-23.0 mm SL); posterior angle of jaws and adjacent membranes with a dark blotch that is visible externally; spinous dorsal fin with no anterior ocellus or dark blotches; pelvic and anal fins are dark, the latter with pale margin (Ref.128653).
