Abstract Pinnixion sexdecennia n. gen., n. sp. is described from three pinnotherid hosts: Austinixa gorei (Manning & Felder, 1989), Pinnixa chaetopterana Stimpson, 1860, and Zaops ostreus (Say, 1817). Females of the new species are distinguished from all other entoniscids by possessing two transverse lobes on oostegite 1 and fused oostegites 2–5; males have a pair of lateral expansions on each of the first two pleomeres. The epicaridium larvae of the new species also have a unique elongated, cylindrical terminal process on the pereopod 6 dactylus. Pinnixion sexdecennian. gen., n. sp. exhibited highest prevalence (> 40%) in North Carolina and Florida. Examination of live specimens of P. chaetopterana infested with mature female isopods showed that larvae are liberated via a pore produced in the wall of the host’s branchial chamber. Mature females of P. sexdecennian. gen., n. sp. occupied nearly all available space within the host crab’s hemocoel. Female P. chaetopterana had higher prevalence than males, and intensities of infestations were also greater in females. Evidence from all locations showed that mature parasites do not inhibit breeding or molting in the host. Our report is one of the few studies on the ecology and biology of entoniscids, a cryptic but ecologically important group of parasitic isopods. We also resolve long-standing nomenclatural issues involving Entione Kossmann, 1881 and Entioninae Codreanu, Codreanu & Pike, 1960, the subfamily to which the new genus and species belongs, by synonymizing Grapsion Giard & Bonnier, 1886 with Entione.

A new genus of Clivinini, Psammocoryza Hogan new genus, and its type species P.vanemdeni Hogan new species (type locality Barra de Serinhaem, Pernambuco, Brazil), is described. Diagnostic features are illustrated by line drawings and photographs. Psammocoryza resembles Halocoryza Alluaud and Schizogenius Putzeys but differs by the peculiar macrosculpture of the pronotum, tuberculate profemora and reduced setation of the gonocoxite.

Abstract The Castle Hayne Formation (Middle and Upper Eocene, North Carolina) contains a rich, diverse and well-preserved sponge fauna, equaled among known Tertiary faunas only by the Eocene fauna of Western Australia and the Miocene fauna of Algeria. It includes among Calcarea two genera of lithonines, (3 new species); among Demospongia one hadromerine, two genera of choristids (2 new species), one cephalorhaphiditid (new genus and species), and three genera and species of plinthosellid lithistids (2 new species); and among Hexactinellida four genera of hexactinosan hexactinellids (1 new genus, 1 new subgenus, 2 new species), two genera of lychniscosan hexactinellids (1 new genus, 2 new species), and a new genus and species of lyssacine hexactinellid. Noteworthy are whole fossil specimens of Geodia and Stelletta (Stolleya), two new genera (one of which is extremely abundant) of cup-shaped hexactinellids with radial fins, and the first fossil species of the Recent genus Verrucocoeloidea. Two faunal facies are recognized: a near-shore one dominated by demosponges and an off-shore one dominated by hexactinellids (with lithonine Calcarea), a pattern known from other published Cretaceous and Tertiary faunas. The off-shore facies is dated from associated fossils as late Claibornian (Auversian); the near-shore facies is probably of approximately the same age because of some common species. The prominence of the extinct plinthosellid lithistids and the absence of rhizomorines and megamorines is noteworthy. All the genera have close relatives in the Cretaceous; all but the plinthosellids have living relatives as well, and five genera are still extant. It is noteworthy that this Eocene fauna is richer than any known North American Cretaceous sponge fauna, even though the Cretaceous was elsewhere very sponge-rich.

Twelve brachiopod taxa are described from the Early Devonian (probable early Emsian) Pa Samed Formation of southern Thailand, including the new genus and species Quasiprosserella samedensis (Ambocoeliidae?) and the new species Plectodonta forteyi, Caplinoplia thailandensis, and Clorinda wongwanichi. They are the first undoubted Devonian brachiopods from Thailand. They represent the deeper-water Benthic Assemblages BA4-5, and, although clearly indicative of the Old World Realm, cannot be assigned to a particular biogeographical region. A new undescribed fauna from the contemporary Zebingyi Formation of Burma (Myanmar) is also noted.

Aldebarania arenitea (Astropectinidae; Asteroidea; Echinodermata) is described from the Rocky Point Member of the Maastrichtian (Upper Cretaceous) Peedee Formation of North Carolina. A turbulent, shallow-water environment is suggested by sedimentary features, a diverse marine fauna, and the morphology of Aldebarania. Aldebarania appears to be a partial ecological equivalent of living Astropecten and Luidia; however, phylogenetic relationships within the Astropectinidae are unstudied and the origin of similarities is unknown.

Abstract. A very distinctive new deep-photic coccolithophore is described from the NE Indian Ocean. The new species is trimorphic with: 200–300 body coccoliths bearing low spines attached by narrow stems to a basal narrow-rimmed placolith structure; up to 18 circum-flagellar coccoliths with tall sail-like spines; and up to 22 coccoliths with moderately elevated spines occurring both around the circum-flagellar coccoliths and antapically. These features make the coccolithophore unique and require placement in a new species and genus. The basal structure, however, shows similarities to a recently recognized group of narrow-rimmed placoliths. Hence, the new coccolithophore provides some support for this grouping as a significant addition to our understanding of coccolithophore biodiversity, and potentially an explanation for a set of anomalous molecular genetic results. In addition the new taxon provides further evidence that the deep-photic coccolithophore community is more diverse than has been assumed.

AbstractThe 11 genera of Nearctic Braconini are keyed: two of them, Myosoma Brullé with a wide pantropical range and Alienoclypeus Shenefelt, new genus, are found chiefly in the Chihuahuan desert and shrub fauna of northern Mexico and the southwestern U.S.A. and are recorded as Nearctic for the first time. Four new species are described in Myosoma: eumystax, impexum, longius, and durango. R. D. Shenefelt describes a new genus and species, Alienoclypeus insolitus. The genus Atanycolimorpha Viereck, 1913 is synonymized with Ipobracon Thomson, 1892. The genus Coeloides is revised for the Nearctic Region; 12 species are described and illustrated. Five of these are new: mexicanus, durangensis, sympitys, tsugatorus, and sonora. One species, C. rossicus (Kokujev), is Holarctic, a new subspecies, betulae, is described from Canada. The following are new synonyms: C. rufovariegatus (Provancher) = (dendroctoni Cushman), C. vancouverensis (Dalla Torre) = (brunneri Viereck), C. crocator (Kirby) = (promontorii Dalla Torre).

An exceptionally well-preserved silicified bivalve from the Upper Permian of Texas is described and assigned to a new genus and species,Cassiavellia galtarae, placed in the family Bakevelliidae. The species represents one of the earliest and best characterized unequivocal occurrences of the multivincular ligament in the superfamily Pterioidea. The silicified material provides a wealth of information on the morphology of inadequately known Paleozoic pterioideans, including hitherto undescribed aspects of the larval shell, auricular sulcus, muscle scars, and dental ontogeny. The discovery of the condyle-fossa complex on the anteroventral shell margin, a feature previously undescibed in Bivalvia, raises the question of the homology and taxonomic significance of the problematic subumbonal ridge-like structures in Pterioidea. In life,C. galtaraewas probably an epifaunal right-pleurothetic bivalve, byssally attached to hard or raised flexible substrata. In addition toC. galtarae, another new species,C. nadkevnae, is placed inCassiavellia.

A new genus and species of janiroidean Asellota, Xenosella coxospinosa, is described from the mid-bathyal slope off the coast of south-eastern Australia. Following a comparison of the new species to several families of broadly similar body shape, with emphasis on monotypic Pleurocopidae, a new family, Xenosellidae, is proposed for the new species. In the course of comparing relevant taxa, the current placements of Prethura Kensley in the Santiidae and Salvatiella Müller in the Munnidae are rejected. The two genera are considered to be incertae sedis within the Asellota superfamily Janiroidea pending further studies.
