Genus Foa


Summary:

An Indo-Pacific cardinalfish genus with at least 9 species, 3-4 found in Australian waters. The genus is currently under study and is poorly known in Australia.

Originally described by Jordan & Evermann in 1905, Foa is diagnosed by a combination of internal and osteological characters.

Species of Foa have the following colour patterns: body almost uniformly dark brownish to reddish, often variably marked with whitish or brownish spot, without ocellae or ocellae-like spots on the head and body or in the fins; pelvic fins with whitish outer rays, middle rays darkish with narrow margin of inner rays lighter; membranes of the first four dorsal-fin spines variably marked with many narrow whitish marks or with a pale zone bordered by blackish membranes distally and proximally; caudal, soft dorsal and anal fins with pale membranes and fin rays or with short, narrow brownish to reddish marks on the fin rays interrupting pale regions forming radiated bar-like appearances on the caudal fin or stripe-like appearances on the soft dorsal and anal fins (Fraser & Randall 2011).
