| ABSTRACT The genus Bostryx Troschel, 1847 is endemic to South America, extending from Ecuador to Chile and Argentina. The southernmost Argentinian species of the genus that inhabit San Luis, San Juan and Mendoza provinces, specially the pre-Andes, Andes and Sierras Pampeanas mountain ranges, were examined. This is the first time the anatomy of Bostryx pastorei (Holmberg, 1912), Bostryx reedi (Parodiz, 1947) and Bostryx strobeli (Parodiz, 1956) has been described.Bostryx cordillerae (Strobel, 1874) is re-described regarding shell and anatomy due to new morphological data. The main differences among the species examined are based on shell characters. The distribution ofBostryx mendozanus (Strobel, 1874) and Bostryx cuyanus (Pfeiffer, 1867), other species... |

| RESUMEN. El género neotropical Psectrascelis Solier (Pimeliinae: Nycteliini) comprende 75 especies que se distribuyen desde el sur de Perú hasta el sur de Argentina y Chile. En este aporte se revisan las cuatro especies de Psectrascelis que habitan en el noroeste de la provincia de Mendoza (Argentina), en los cordones montañosos de la Precordillera y Cordillera de los Andes: P. deplanata (Lacordaire, 1830), P. vestita (Lacordaire, 1830), P. mamillonea (Lacordaire, 1830) y P. semistrigosa Fairmaire, 1903. Se proveen redescripciones con nuevos caracteres morfológicos, fotografías de adultos y de los pronotos, e ilustraciones de genitalia masculinos. Se consigna la distribución geográfica y rangos altitudinales para cada especie, estableciendo las provincias... |

| The La Laja Formation lies exposed almost continuously along the western margin of two hill ranges, i.e., the Sierra Chica de Zonda and Sierra de Villicum. This limestone unit bears a remarkable fauna of Cambrian trilobites. In this work we analyse the Delamaran trilobite fauna from the upper part of the El Estero Member and the lower third of the Soldano Member of the La Laja Formation. Taxa described are Glossopleura walcotti Poulsen, Glossopleura lodensis (Clark), Fieldaspis sp., and Prozacanthoides zondaensis n. sp. The Poliella denticulata, Mexicella mexicana?, and Glossopleura walcotti Zones are documented; these had been previously included in a hiatus. Trilobites-based correlations are established between the La Laja Formation and olistoliths of... |

| La quebrada San Isidro es una localidad clásica para el estudio del Ordovícico en la Precordillera de Mendoza. Las formaciones Estancia San Isidro y Empozada incluyen rocas alóctonas del Cámbrico y Ordovícico en una matriz pelítica ordovícica. Los graptolitos, conodontes y trilobites son abundantes en estas unidades. En este trabajo se describe una graptofauna del Darriwiliano tardío procedente de la facies de pelitas verde-grisáceas de la Formación Estancia San Isidro, expuesta en la margen norte de la quebrada San Isidro. Estos graptolitos refieren a la Zona de Pterograptus elegans o, probablemente, de Hustedograptus teretiusculus. La graptofauna está integrada principalmente por diplográptidos, dominando el género Archiclimacograptus Mitchell y, en... |

| A brachiopod fauna dominated by Hindella crassa (J. de C. Sowerby), and also including an indeterminate pseudolinguloid, Leangella (Leangella) america sp. nov., Eoplectodonta (Eoplectodonta) duplicata (J. de C. Sowerby), Fardenia sp., Glyptorthis vidari (Baarli)., Dolerorthis plicata (J. de C. Sowerby), an indeterminate giraldiellid, Dalmanella sp., and Stegerhynchus pusillum (J. de C. Sowerby), is described from the La Chilca Formation exposed at Mogotes Azules, San Juan Province, Argentina. The age of the fauna is Early Silurian (Llandovery: Rhuddanian) and it is compared with other Rhuddanian brachiopod faunas both from Gondwana and elsewhere. The brachiopod faunas of Gondwana, despite their relatively low diversity, had much in common with those from... |

| A detailed study is carried out on the taxonomy of the bryozoan fauna from the upper levels of the San Juan Formation (Darriwilian) in the Talacasto and Cerro Viejo sections, Argentinean Precordillera. Three bryozoan genera are described and two new species are erected: Lamottopora multispinosa sp. nov., Aostipora sanjuanensis sp. nov., and Phylloporinidae sp. indet. The paleoecological significance of the bryozoan fauna is discussed. The ramose bryozoans Lamottopora and Aostipora dominate in the Talacasto section. Some colonies probably lived attached directly to the substrate, while others occur attached to the surface of the abundant sponge fauna in the section. The majority of bryozoans at the Cerro Viejo section occur as epibionts, with bases attached... |
