Pseudotolithus


Pseudotolithus is a genus of marine ray-finned fish belonging to the family Sciaenidae, the drums or croakers. The species in this genus are found in the Eastern Atlantic Ocean.

Taxonomy

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. P. typus was designated as the type species by virtue of being named typus. Ethelwynn Trewavas placed the eastern Atlantic Afrotropical sciaenids, Pseudotolithus and Pteroscion, in the tribe Pseudotolithini. Other workers have placed this tribe in the subfamily Pseudotolithinae alongside the tribe Miracorvini, Miracorvina and Pentheroscion. 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.

Etymology

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

Species

Pseudotolithus has the following valid species classified within it:Pseudotolithus brachygnathus Bleeker, 1863Pseudotolithus elongatus Pseudotolithus epipercus Pseudotolithus moorii Pseudotolithus senegalensis Pseudotolithus senegallus

Characteristics

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. The largest species in the genus is the law croaker which has a maximum published total length of while the smallest is the bobo croaker at.

Distribution

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