COLLADO Departamento de Ciencias Básicas, Facultad de Ciencias, Universidad del Bío-Bío, Avenida Andrés Bello s/n, Casilla 447, Chillán, Chile. Fundación Chile Natura. E-mail: [email protected] In the family Cochliopidae, Heleobia Stimpson, 1865 is the most speciose genus in South America, with about 90 species (Hershler & Thompson 1992; Cazzaniga 2011). A recent molecular and morphological analysis performed in northern Chile (Atacama Desert) showed that the previously undescribed springsnails from Aguada de Chorrillos belong to Heleobia (Collado et al. 2013). In this study I formally describe this new species. Although this paper does not treat morphology in detail, the anatomical characters, in combination with the previously published molecular data provides a strong basis for recognizing this population as a distinct species. Material and methods The snails were collected alive from Aguada de Chorrillos (27°12′32.40″ S; 70°57′03.30″ W), Atacama Desert, northern Chile using a sieve of 0.5 mm mesh width and stored in absolute ethanol. The shells, opercula and penes were photographed and measured using a Motic SMZ–168 Stereo Microscope with a Moticam 2000 integrated digital camera. Type specimens were deposited in the Museo de Zoología de la Universidad de Concepción (MZUC), Concepción, Chile. -

Phylogenetic Relationships Within the North American Hydrobiid Snail Genus Tgonia: Taxonomic and Biogeographic Implications
Phylogenetic Relationships Within the North American Hydrobiid Snail Genus Tgonia: Taxonomic and Biogeographic Implications Robert Hershleri , Hsiu-Ping Liu2, and Margaret Mulvey3 'Department of Invertebrate Zoology, National Museum of Natural History, Smithsonian Institution, Washington, D.C. 20560; 2Department of Biology, Olin Hall, Colgate University Hamilton, NY 13346; 3Savannah River Ecology Laboratory, P.O. Drawer E, Aiken, South Carolina 29802. Introduction The aquatic biota of western North America is of interest from the standpoint of evolutionary biology and biogeography because elements often are profoundly isolated by inhospitable deserts and mountain ranges, live in extremely restricted and/or harsh environments, and present distributional and phylogenetic patterns which have been molded by the extremely complex and dynamic(Cenozoi physical history of the region. Biotic distributions and evolutionary relationships may also provide clues as to early regional drainage relationships for which geological evidence often/has been obscured by subsequent deposition, deformation and erosion. Whereas early regional biogeographic treatments of fishes (e.g., Hubbs and Miller 1948; Hubbs 1974) focused on dispersal opportunities afforded by a highly integrated late Pleistocene "pluvial" drainage, Minckley et al. (1986) accepted great antiquity (Oligocene- Miocene) of this fauna and consequently emphasized the complex role of geological events in effecting vicariance, and the likelihood that fishes have been introduced to and/or transferred within the region by rafting on allochthonous terranes, intra-continental microplates, and other tectonically displaced or extended crustal fragments. The limited phylogenetic data then available for western American fishes demonstrated partial congruence with hypotheses for historical area relationships advanced by these authors, although they emphasized the need for additional Sich studies. -
