Taxonomy edit

Pseudotolithus was first proposed as a genus in 1863 by the Dutch physician, herpetologist and ichthyologist Pieter Bleeker when he described the new species P. brachygnathus, P. epipercus and P. typus.[2] P. typus was designated as the type species by virtue of being named typus.[1] Ethelwynn Trewavas placed the eastern Atlantic Afrotropical sciaenids, Pseudotolithus and Pteroscion, in the tribe Pseudotolithini.[3] Other workers have placed this tribe in the subfamily Pseudotolithinae alongside the tribe Miracorvini, Miracorvina and Pentheroscion.[4] However, the 5th edition of Fishes of the World does not recognise tribes or subfamilies within the Sciaenidae which it places in the order Acanthuriformes.[5]

Etymology edit

Pseudotolithus prefixes Otolithus with pseudo meaning "false" due to Bleeker's perceived false resemblance between these fishes and those of that genus.[6]

Species edit

Pseudotolithus has the following valid species classified within it:[7]

Characteristics edit

Pseudotolithus croakers have a carrot-shaped swim bladder running the whole length of the body cavity with a pair of long tube-like appendages growing out of its front. These appendages branch into as many as 32 tubules. They do not have any barbels on the chin.[3] The largest species in the genus is the law croaker (P. senegallus) which has a maximum published total length of 230 cm (91 in) while the smallest is the bobo croaker (P. elongatus) at 47 cm (19 in).[7]

Distribution edit

Pseudotolithus croakers are found in the Western Atlantic Ocean from Morocco in the north to Angola in the south.[8]
