|---|---|---|
| G. Marramà and G. Carnevale 2017 | Holosteine paralepidid with very elon- gated body and fineness ratio of 15.0–16.0; head is of about five to six times SL; upper jaw terminating below the ventral margin of the orbit; prominent, non- ossified and horizontally directed projection forming the anterior tip of the lower jaw; articular–quad- rate joint located below the posterior margin of the orbit; eight branchiostegal rays; small recurved teeth on premaxilla; large, thin and pointed teeth on pal- ate and lower jaw without corrugate pattern or ser- rate margins; epineurals and epipleurals extending throughout the vertebral column, being thicker and more ossified in the caudal region; most epineurals bifid or trifid proximally; 106–112 vertebrae of which about 30% are caudal; dorsal fin with 18–20 rays; about 19–22 anal-fin rays; about 10–12 pelvic-fin rays; caudal fin with 19–20 principal rays and about 10–12 dorsal and ventral procurrent rays; five or six autog- enous hypurals, of which the first two appear to be partially fused; proximal ends of the epaxial caudal- fin rays that extensively overlap the associated hypurals; bony fulcral scales just in front of the upper and ventral caudal-fin lobes; body completely naked, with a broad, uniform, mid-dorsal brown-pigmented band along the back. |
