Morphology | Morphometrics
This species is characterized by the following: dorsal coloration when fresh strongly ornamented, mottled yellowish brown; side of the head with black spots; nasal barbel with 2 simple lobes; postspiracular lobes are poorly developed, distance across preorbital group 1.2-1.4 times interspace between preorbital group and postspiracular lobe (PO/PO-PS1), 12-14 times base length of anterior postspiracular lobe (PO/PS1); base of anterior postspiracular lobe 9-12 in its distance from postorbital group (PO- PS1/PS1), 5-6 in its distance from posterior postspiracular lobe (PS1-PS2/PS1); above eye is a weak tubercle; back without wart-like tubercles; dorsal fins low, raked, not upright; first dorsal-fin origin over mid pelvic-fin base; interdorsal space 0.3-0.4 times the anal-fin base length; anal-fin inner margin 1.1-1.2 times the anal-fin posterior margin; 18-20 teeth in upper jaw, medial row at symphysis of upper jaw absent; 47-52 monospondylous centra; 145-150 total vertebral centra (Ref. 74934).
Collected from the inner continental shelf off southwestern Australia (Ref. 74934).
