Cladistic Analysis of 37 Mediterranean Bogidiellidae (Amphipoda), Including Bogidiella arista, New Species, From Turkey

A new subterranean amphipod species, Bogidiella (Medigidiella) arista, found in the mesopsam mic ground waters of southern Anatolia, Turkey, is described, together with Bogidiella (Bogidiella) calicali Karaman, the latter being recorded for the first time in the eastern Mediterranean. A cladistic analysis of 37 Mediterranean species of the family Bogidiellidae is performed, using 4 species from the Canary Islands as an outgroup. Alternatively, 2 cladistic software packages, PAUP 3.1.1 and HENNIG86, are employed to calculate consensus trees of minimal length. The resulting trees show more or less identical robust clades, characterizing a central, a central-eastern, and an eastern Mediterranean group. Apart from this pattern of major geographical clusters, all species of the subgenus Medigidiella appear as a robust, monophyletic clade as well. This initial attempt to analyze the phylogeny of Mediterranean bogidiellids forms a useful basis for further, extended studies, using either different outgroup taxa or additional morphological data

Crustacean fauna

12 p. : ill. ; 26 cm.Includes bibliographical references (p. 11-12)."The only marine Jurassic decapod fauna in North America is found in the Stockade Beaver Member of the Sundance Formation of Wyoming. The preservation of these crustaceans is only moderately good, permitting, at most, identification to the generic level of these soft-shelled decapod shrimp. The faunal assemblage, composed of Antrimpos sp., Bombur sp., Mecochirus sp., a glypheid, and some unidentifiable anomuran remains, can be compared with Triassic and Jurassic material from European deposits, which form part of the biologic continuum of crustaceans throughout the Lower Mesozoic"--P.

Redescription of Americlus rankini (Woodward, 1868) (Pancrustacea: Cyclida: Americlidae) and interpretation of its systematic placement, morphology, and paleoecology

The best-preserved Scottish species of a cyclidan is reinterpreted, based upon recent advances in cyclidan paleobiology. Americlus rankini (Woodward, 1868) is one of the best-preserved members of this crustacean group, and its morphology suggests that it and related forms exhibited a unique and distinct morphology within Multicrustacea. Paleoecological evidence suggests that the animal was most likely free living, possibly as a scavenger, in a marginal marine environment. Americlus lived in Laurentia during the Middle Mississippian (Visean) to Middle Pennsylvanian (Moscovian)

The systematics of sponges

Review of: Systema Porifera, edited by J. N. A. Hooper and R. W. M. van Soest. Kluwer Academic Publ., Dordrecht, Netherlands, 2002, 1708 pp., ISBN 0-306-47260-0 This seems to be a time for the publication of big compendia. One would have thought that in this age of the internet one would be turning to convenient web-sites to find the latest catalogues of data and information about biodiversity of animal groups. Indeed, such do exist, and many of them are remarkably detailed and informative. Nevertheless, there has been a steady stream lately of traditional hardcopy volumes presenting systematic and taxonomic overviews of various groups of animals. This handsome two-volume set is amongst the latest example of these kinds of books to appear
