Prognathodes carlhubbsi (Nablant, 1995)


Southern Scythe butterflyfish,     Southern Scythe-marked butterflyfish



Body a strongly compressed oval disc; mouth small, at end of a short, pointed, tubular snout that is 1/3-1/2 head length; cheek bone free and smooth; teeth long and slender; dorsal fin XIII, 19-20, triangular shape, 3rd  or 4th  spine longest, with notch between spiny and soft parts; anal rays III,14-16, 2nd  anal spine very long, much longer than 3rd; rear edges of dorsal and anal fins vertical; tail edge straight to rounded; lateral line in a high arch, incomplete (ends under dorsal fin), with 37-49 scales; scales rough, covering head and body, a low scaly sheath on base of dorsal fin.



Yellow with prominent black scythe-like marking on side, also a blackish diagonal band from snout to dorsal fin origin.


Size: grows to 13 cm.

Habitat: rocky reefs.

Depth range 12-270 m.


The Galapagos Islands, Cocos and Malpelo.


    Very similar to P. falcifer, which is found in the northern part of our region. P falcifer and P carlhubbsi differ as follows: 1. dark band along the snout is  black in  P. carlhubbsi and pale grey in  P. falcifer.2. the black scythe mark reaches the base of the dorsal fin spines in  P. carlhubbsi  but ends well under those spines in  P. falcifer.

3. the upper back and base of the dorsal fin are grayish in P. carlhubbsi and yellow in P. falcifer. Because the differences between P. carlhubbsi and P. falcifer are quite small a genetic study of their relationship could help clear up doubts about the validity of P. carlhubbsi.
