Book Description
Ten synapomorphies are described that support the proposed sister group relationship of the Eocene Kushlukiidae and the Eocene to Recent Luvaridae as the superfamilial clade Luvaroidea at the node between the siganid and zanclid+acanthurid clades of acanthuroid fishes. The Kushlukiidae previously have been known only on the basis of Kushlukia permira Danilchenko from the Eocene of Turkmenistan, but another species of that age is shown to have been present in India; the latter is not given a new specific name because the two specimens of it are only fragments. In addition to the well known Recent species Luvarus imperialis, three fossil species have been referred to the Luvaridae: Proluvarus necopinatus Danilchenko from the Eocene of Turkmenistan is here recognied as a valid species of Luvarus, with Proluvarus becoming a junior synonym of Luvarus; Eoluvarus bondei Sahni and Choudhary from the Eocene of India is shown to be not a luvarid but, rather, a member of the fossil perciform family Exelliidae, the affinities of which family are poorly understood; Luvarus praeimperialis Arambourg from the Oligocene of Iran is shown to be not a luvarid but, rather, a representative of the new genus Aluvarus of such uncertain affinity that we simply place it incertae sedis among the percomorphs. Among the materials used by Danilchenko in the description of Proluvarus necopinatus only the holotype and the five other largest specimens (about 326-495 mm SL) represent that species. All of the other specimens are smaller than about 215 mm SL and represent two new species of a new genus of luvarid, Avitoluvarus dianae and A. mariannae. Numerous derived features are used to define both the Kushlukiidae and Luvaridae. Within the Luvaridae, the preponderance of derived features is found in Luvarus, whereas Avitoluvarus has only two unequivocal synapomorphies. The Luvaroidea, therefore, are represented by the Eocene Kushlukiidae with one genus and two species (Kushlukia permira and K. sp.) and the Luvaridae with one Eocene genus with two species (Avitoluvarus dianae and A. mariannae) and one genus, Luvarus, with one Eocene species, L. necopinatus, and one Recent species, L. imperialis.

Book Description
Take your knowledge of fishes to the next level Fishes of the World, Fifth Edition is the only modern, phylogenetically based classification of the world’s fishes. The updated text offers new phylogenetic diagrams that clarify the relationships among fish groups, as well as cutting-edge global knowledge that brings this classic reference up to date. With this resource, you can classify orders, families, and genera of fishes, understand the connections among fish groups, organize fishes in their evolutionary context, and imagine new areas of research. To further assist your work, this text provides representative drawings, many of them new, for most families of fishes, allowing you to make visual connections to the information as you read. It also contains many references to the classical as well as the most up-to-date literature on fish relationships, based on both morphology and molecular biology. The study of fishes is one that certainly requires dedication—and access to reliable, accurate information. With more than 30,000 known species of sharks, rays, and bony fishes, both lobe-finned and ray-finned, you will need to master your area of study with the assistance of the best reference materials available. This text will help you bring your knowledge of fishes to the next level. Explore the anatomical characteristics, distribution, common and scientific names, and phylogenetic relationships of fishes Access biological and anatomical information on more than 515 families of living fishes Better appreciate the complexities and controversies behind the modern view of fish relationships Refer to an extensive bibliography, which points you in the direction of additional, valuable, and up-to-date information, much of it published within the last few years Fishes of the World, Fifth Edition is an invaluable resource for professional ichthyologists, aquatic ecologists, marine biologists, fish breeders, aquaculturists, and conservationists.

Book Description
The published works are derived from the Zoological catalogue of Australia database. Taxa in the Australian fauna are divided among volumes to form sets of about 1800-2000 species available names, such that each volume comprises the whole or part of one or more major groups.

Book Description
Four genera of fossil siganid fishes of early Eocene to early Oligocene age are recognized in addition to the single Recent genus. The osteological features of these five genera are described and illustrated. A phylogenetic analysis utilizing PAUP indicates that the genera have the following phyletic sequence convention: Ruffoichthys Sorbini (two species from the middle Eocene of Italy)--Eosiganus, new genus (one new species from the middle Eocene of Russia)--Siganopygaeus Danilchenko (one species from the early Eocene of Turkmenistan)--Protosiganus Whitley (one species from the early Oligocene of Switzerland)--Siganus Forsskål (27 Recent species in the Indo-Pacific).
