Features

Diagnosis. A subspecies of Banjos banjos distinguished from other subspecies by the following combination of characters: least interorbital width 5.8–8.1 (mean 6.8) % of SL; first dorsal-fin spine length 4.5–8.0 (6.1) % of SL; second dorsal-fin spine length 11.2–18.3 (14.0) % of SL; eighth dorsal-fin spine length 9.5–18.7 (12.5) % of SL.

Colour

Head and body silvery white to grey or brown, darker dorsally; small specimen with several indistinct dark stripes on side of body and small black blotch on caudal-fin base; frontal portion of head blackish; lips whitish; eye dull yellow. Dorsal-fin spines and associated membrane pale brown (membrane with broad central translucent area in small specimens); soft dorsal-fin rays with brownish tinge, associated membrane translucent with a white dorsal margin and large black rounded blotch anterodorsally, subequal to orbit in size. Anal fin membrane translucent, anterior portion brown, with narrow white distal margin. Pectoral fin tinged with pale brown; lunate or semicircle dark blotch on base. Pelvic-fin soft rays and membrane black. Caudal fin semi-translucent with broad brown to black band posteriorly in large specimens (5 dark blotches in small specimens), with narrow white distal margin.

Etymology

The subspecific name brevispinis is derived from the Latin word meaning 'short-spine', alluding to the subspecies possessing relatively short dorsal-fin spines, compared with B. b. banjos.
