Biometric and meristic data as in Table
13. General description as for genus. Head depressed and
broad, body moderately compressed; head width 55–60%
HL. Interorbital space flat. Eye diameter 10–15% HL.
Premaxillary tooth band not exposed when mouth is closed.
Dorsal profi le rising evenly but not steeply from tip of snout
to origin of dorsal fi n, then sloping gently ventrally from
there to end of caudal peduncle. Ventral profi le horizontal
to origin of anal fi n, then sloping dorsally to end of caudal
peduncle. Adipose-fi n base short, approximately as long as
anal-fi n base; maximum height 5.0–7.2% SL (2.3–3.2 times
in length of adipose-fi n base). Adipose-fi n origin separated
from base of last dorsal-fi n ray by distance of 7.7–10.9% SL.
Dorsal spine stout, with 6–10 serrations along posterior edge.
Anteriormost branch of each dorsal-fi n ray longer than other
branches, imparting jagged distal margin to fi n; membranes
broad, imparting rounded appearance. Adpressed dorsal fi n
(excluding fi lamentous extensions of rays) reaching beyond
adipose-fin origin; filamentous extensions not reaching
beyond middle of adipose-fi n base. Pectoral spine stout,
with 13–18 large serrations along posterior edge. Anal fi n
rounded, origin slightly posterior to adipose origin. Caudal
fi n forked; upper and lower lobes rounded. Maxillary barbels
reaching barbels reaching at least vertical through base of
last anal-fi n ray (221–265% HL). Maximum recorded size
420 mm SL
