A New Species

AbstractFive genera of anthaspidellid and streptosollenid demosponges are described from the Ordovician Lenoir Limestone near Lenoir City, Loudon County, Tennessee, USA including: Rhopalocoelia regularis Raymond and Okulitch, Rugocoelia loudonensis n. sp., Psarodictyum sp. (Anthaspidellidae), Allosacus pedunculatus n. sp., and Zitelella varians Raymond and Okulitch (Streptosolenidae). These findings confirm the major paleobiogeographic picture for Laurentian sponges (i.e., the differential distribution of sponge faunas along both North American margins), because none of these eastern margin species has been reported from western margin faunas. Only one genus typical of the Great Basin fauna, Rugocoelia Johns, 1994, is reported from Tennessee, but as a new species. Possible explanations are discussed for this differential distribution, mainly related to climatic constraints or sedimentary differences, preventing the free distribution of sponge species between Laurentian continental margins.UUID: http://zoobank.org/2b990a4c-7bc8-4eb6-b8a9-fe4ecf7bdbf9

Molecular Characters

Okanagana boweni sp. n. is described from the western margin of the Great Basin of North America. The new species is diagnosed from allopatric O. simulata Davis and sympatric O. utahensis Davis using morphological, bioacoustical, and molecular characters. The distribution of this new species coincides with the Walker Lane region that lies along the border of California and Nevada, USA. Based on geography, bioacoustics, morphology, and molecular phylogenetics, we hypothesize that O. boweni sp. n. is the allopatric sister species of O. simulata.

A New Species

Mangroves create unique ecological environments, furnishing a habitat opportunity for many species. The majority of published information on mangrove sponges comes from the Caribbean while few data are available from Indo-Pacific mangrove sponges. In general, species diversity of sponges in mangroves is lower than adjacent subtidal habitats in both the Caribbean and Indo-Pacific. The aim of this study is to report the first data about sponge species diversity of two mangrove forests from Bangka Island (North Sulawesi, Indonesia) and to describe a new sponge species associated with the mangroves. The survey found 19 species, belonging to 11 families and 15 genera; the samples were collected on mangrove trunks, on the roots or on the surrounding bottom. The majority of the species are typical of coral reef but two of them have been previously found only in lagoons or in mangrove habitats. These new data enlarge our knowledge about Indonesian sponges diversity and suggest the urgency to consider Indonesian mangroves as an important but underestimated element in coral reef ecological dynamics.

A New Species

A new sponge species Coelocarteria agglomerans sp. nov. (Isodictyidae: Mycalina: Poecilosclerida) is described from the reef slopes of Bunaken National Marine Park, North Sulawesi, Indonesia. The new species can be separated from the other two congeneric species: C. singaporensis and C. spatulosa by several characters concerning sponge surface, fistule shape, form and size of the spicules and habitat. In detail it differs from C. singaporensis in the presence of strongyles instead of oxeas as main megascleres and of spines in the shaft of palmate isochelae. It differs from C. spatulosa in the absence of characteristic fistules with spatula shaped hoods and in spicule size, because both categories of strongyles and palmate isochelae are remarkably larger in the latter.

Two species of hubbardiid microwhipscorpions (Schizomida: Hubbardiidae) are recorded from the Brazilian Atlantic Forest. Rowlandius linsduarteae sp. nov. is described and illustrated based on specimens from Mata do Buraquinho forest reserve, João Pessoa, state of Paraíba, northeastern Brazil. This species is apparently related to Rowlandius sul Cokendolpher & Reddell 2000, the only species of the genus known from continental South America, and represents new evidence of a biogeographic relationship between Amazonia and the northeastern Brazilian Atlantic Forest. Stenochrus portoricensis Chamberlin, a widely distributed species, is newly recorded from the states of São Paulo and Bahia, respectively, in southeastern and northeastern Brazil. The latter record refers to several female specimens associated with abandoned arboreal termite nests in a cocoa plantation.

A New Species

AbstractSpecies of the monogenean genus Quadriacanthus mainly infect fish belonging to the Siluriformes, especially the genera Clarias, Heterobranchus or Bagrus, and their host specificity is strict (oioxenous) or narrow (stenoxenous). An examination of the gills of 19 Papyrocranus afer from Lake Ossa, South Cameroon, revealed for the first time the presence of a species of Quadriacanthus from a fish host belonging to the Notopteridae. The morphology and the size of sclerotized parts of haptor and the male and female copulatory complexes suggest that this monogenean is a new species named Quadriacanthus euzeti n. sp. The fish genus Papyrocranus differs taxonomically from the usual fish hosts of Quadriacanthus and hence the presence of a species belonging to this genus on the gills of this host suggests the occurrence of a lateral transfer of Quadriacanthus from species belonging to Clarias or Bagrus which live sympatrically with P. afer in Lake Ossa.

Sixteen sponge species were recorded from Little Letite Passage, an area of highvelocity tidal currents located in the Bay of Fundy near Deer Island, New Brunswick, Canada. Of these 16 species, four species (Myxilla fimbriata, Hymeniacidon heliophila, Hemigellius sp. aff. flagellifer, and Crella rosea) have not previously been recorded from the Bay of Fundy. One new species, Hymedesmia canadensis, is described, based on the presence of a second peculiar chelate microsclere added to the spicule armament.

A New Species

We describe a new species of toad from the Great Basin region of northern Nevada belonging to the Bufo (Anaxyrus) boreas species complex. This cryptic species was detected through genetic analyses of toad populations sampled throughout the Great Basin and the morphological evidence was quantified through extensive sampling of live toads within the region. The new species has the smallest body size in the species complex, and can be further diagnosed from other species in the complex by its large tibial glands and unique coloration. The known distribution of the new species is restricted to an area less than 6 km2 in Dixie Valley, Churchill Co., Nevada. The Great Basin is an arid region where aquatic resources are both rare and widely scattered, making habitat suitable for anuran populations highly vulnerable to anthropogenic change. The habitat occupied by this newly described species is threatened by the incipient installation of geothermal and solar power development projects that require the water that defines its habitat.
