A New Species

A new species of colonial athecate hydroid, Rhysia fletcheri, is described from Vancouver Island, British Columbia, Canada, and from Friday Harbor, Washington, U.S.A. Its relationship to Rhysia autumnalis Brinckmann from the Mediterranean and Rhysia halecii (Hickson and Gravely) from the Antarctic and Japan is discussed. Rhysia fletcheri differs from Rhysia autumnalis and Rhysia halecii in the gastrozooid having distinctive cnidocyst clusters on its hypostome and few, thick tentacles. Most of its female gonozooids have no tentacles. Colonies of R. fletcheri are without dactylozooids. The majority of R. fletcheri colonies are found growing on large barnacles or among the hydrorhiza of large thecate hydrozoans. Rhysia fletcheri occurs in relatively sheltered waters of the San Juan Islands and on the exposed rocky coast of southern Vancouver Island.

A New Species

Several species of solitary entoprocts of the genera Loxosoma and Loxosomella occur on maldanid polychaetes or in their tubes (Nielsen 1964). New species turn up almost every time maldanids from new localities are studied, and the species described below has been the subject of a study of spiral cleavage (Merkel et al. 2012). This paper describes a new species of Loxosomella from tubes of the maldanid polychaete Axiothella rubrocincta (Johnson, 1901) from False Bay, San Juan Island, WA, USA.

A New Species

Silicified material from the Early Caradoc part of the Las Aguaditas Formation in San Juan Province, Argentina, includes a nearly complete growth series for a new species of the tropidocoryphid Stenoblepharum Owens, 1973. Cladistic analysis of Stenoblepharum species indicates that S. astinii new species is most closely allied to the Early Caradoc S. strasburgense (Cooper, 1953) from Virginia. Chinese species of Stenoblepharum are sister group to a Baltic/Laurentian clade. A single adult-like protaspid stage occurs in the life cycle of S. astinii, closely resembling the protaspis of Decoroproetus. It is preceded by a non-adult-like first protaspid instar that appears to be characteristic of Proetoidea in general but contrasts markedly with the early larval stages of other taxa in Proetida.

Pitcairnia anarosae, known until now from the municipality of San Juan Colorado, Oaxaca, Mexico, is described and illustrated. The new species is compared with P. singularis, from which differs by the plant height (19–40 vs 15–25 cm) the number of leaves (5–8 vs 3–4), and the morphology, color (red vs white) and length of flowers.

A New Species

The largest known member of the mammalian order Multituberculata is the taeniolabidid Taeniolabis, which is known from Puercan (early Paleocene) localities in northern New Mexico, Utah, Montana, and southern Saskatchewan. A locality in the Ludlow Formation of southeastern Montana has produced remains of a new species, T. lamberti n. sp., which is based on a well-preserved dentary with teeth. Isolated teeth from the Tullock Formation of northeastern Montana are referred to T. lamberti n. sp. and Taeniolabis sp.Taeniolabis triserialis, known exclusively from the San Juan Basin, New Mexico, is shown to be a junior synonym of T. taoensis. Taeniolabis sulcatus, the type species of the genus, is recognized as a nomen dubium and is synonymized with T. taoensis based on general morphology and occurrence in the same stratigraphic unit and collecting area (lower part of the Nacimiento Formation, San Juan Basin, New Mexico). The name T. taoensis is retained for this taxon in the interest of nomenclatorial stability. These synonymies limit to one the number of species of Taeniolabis recognized in the San Juan Basin, New Mexico. It is proposed that T. taoensis be designated the new type species of the genus Taeniolabis.

A New Species

The Rhinella granulosa species group was taxonomically reviewed by Gallardo (1965) and most recently by Narvaes and Rodrigues (2009). This last review recognized twelve species (Rhinella granulosa, R. pygmaea, R. bergi, R. major, R. mirandaribeiroi, R. azarai, R. nattereri, R. fernandezae, R. dorbignyi, R. merianae, R. humboldti, R. centralis) distributed along the open habitats of South America and Panama (Narvaes & Rodrigues, 2009). Recently, a new species (R. bernardoi) was described from San Juan province, in Argentina (Sanabria et al., 2010). Both revisions and the description paper were based on morphological and morphometric characteristics. Despite the relevance of acoustic parameters in anuran taxonomy, the advertisement call of only one species of the R. granulosa group has been formally described. Köhler et al. (1997) described the vocalization of Rhinella major from Bolivia, considered at that moment as the subspecies Bufo granulosus mini. Herein we describe the advertisement call of Rhinella granulosa, a species occurring in the Caatinga domain of northeastern Brazil according to Narvaes and Rodriguez (2009).

A New Species

A new species of Hymenomonas Stein, Hymenomonas lacuna sp.nov. from San Juan Island, Washington, U.S.A. is described using light and electron microscope techniques. The cells normally occur in non-motile clumps growing on the sides of the culture vessel. Each cell has a body covering composed of a single layer of coccoliths of unusual construction and several layers of circular unmineralized rimless scales. Occasional small elliptical scales are sometimes found.The general cytology of the cells is discussed with special attention paid to the unusual pyrenoid and the role of the Golgi body in scale and coccolith production.The relationship of this species to H. roseola Stein is discussed.
