Latin American Journal of Aquatic Research, vol. 40, núm. 4, noviembre, 2012, pp. 929-935 Pontificia Universidad Católica de Valparaíso Valparaiso, Chile Available in: http://www.redalyc.org/articulo.oa?id=175025197023 Abstract The family Planorbidae in Chile is represented by the genus Biomphalaria Preston, 1910, consisting of seven species distributed from Isluga to Puelo River. Of these species, only Biomphalaria peregrina widely distributed in the neotropical and Biomphalaria aymara from Isluga are recognized based on the morphology of the reproductive system and radula, characters that were used in the following study to differentiate Biomphalaria cristiani as a new species of this group and first record of the family in Chilean Patagonia, extending its current distribution range. The characters for the diagnosis of B. cristiani are: truncated vestigial vaginal pouch, lack of development of the penis retractor muscles, penis sheath shorter than the prepuce, oviduct longer than the spermiduct and vas deferens thinner and longer than the penis sheath, similar size to the prepuce. The type locality of B. cristiani nov. sp. is Laguna Cisnes (47°7'10.02"S; 72°27'40.65"W), Aysén region.

Aquatic Snails
Aquatic snails - Aquatic gastropods Abundance: Unknown Status: NSSU NatureServe: G5 SNR Population Status: Unknown Limiting Factor: Unknown Comment: None Introduction Aquatic snails and limpets or class Gastropoda are soft bodied molluscs with a spiral, coiled disk-shaped (snails), or cone-shaped shell (limpets). Aquatic snails and limpets are composed of a muscular foot, head, visceral mass (contains organs), and a mantle (secretes shell). Shell length or width varies between 0.2 and 7 cm (0.1 to 2.8 inches). About 526 species of aquatic snails and limpets are known across North America (Brown and Lydeard 2010). According to NatureServe (2009), 54% of the snails and limpets in North America are considered critically imperiled or imperiled (G1/T1 or G2/T2). Aquatic snails and limpets are typically scrapers, eating algae, microbes, fungi, and detritus off of solid substrate such as rocks, logs, or macrophytes (Smith 2001). Freshwater snails and limpets tend to lay eggs in spring. Most snails and limpets lay eggs on substrate, but the families Viviparidae and Thiaridae are live-bearers. The families Physidae, Lymnaeidae, Planorbidae, Ancylidae, Valvatidae, Acroloxidae, and Lancidae are hermaphroditic, but females and males are separate in all other families of freshwater gastropods. Most snails and limpets live 9 to 15 months; however, some species can have 2 to 3 generation in one year especially in warmer climates and others may live up to 4 years. In Wyoming, 50 species and subspecies of freshwater snails and limpets are known (Beetle 1989)(NatureServe 2009). Of these gastropods, 16% are considered critically imperiled or imperiled (G1/T1 or G2/T2).

Snails hatched in May–June and kept in pairs usually started reproducing 42–114 days after hatch- ing, at the shell width of 3.0–5.2 mm and 3.75–5.1 whorls. Some of them continued reproduction next spring. Snails hatched in July-August and kept in pairs produced their first cocoons next year. In the year of hatching the snails produced their last cocoons till October, next year – usually till August. During their lifetime snails kept in pairs produced a maximum of 122 cocoons with a total of 511 eggs (per snail), and the number of eggs per cocoon ranged from 0 to 9. Snails kept in isolation produced a maximum of 10 cocoons (most without eggs, the remaining ones with eggs devoid of oocytes). The life span was 68–776 days (mean 423).

Gillett-Kaufam2 Introduction Distribution The marsh rams-horn, Helisoma (Planorbella) trivolvis The marsh rams-horn is native to North America, with its (Say), is a species of air-breathing freshwater aquatic snail habitat ranging from northern arctic Canada and Alaska that is native to Florida. It belongs to the family Planorbi- to Florida. This species has also been discovered in parts dae, commonly known as the ramshorn snail, which comes of Mexico, Peru and Ecuador. This species of snail is often from the shape of its shell. seen breathing air or grazing on plants on or near the surface of the water (Baker 1945). The marsh rams-horn can be also be found in the bottom of swamps, lakes, rivers, and ponds. Description The marsh rams-horn is characterized by its sinistral (left-turning) flat coil shell. The color of the shell ranges from light to dark brown with the body of the snail similar in color. The visible portion of the body of the snail consists of a head, a foot and a pair of tentacles. The snail uses its singular foot for movement via muscle contraction. This Figure 1.

MALACOLOGIA, 2006, 49(1): 189−208 FRESHWATER GASTROPODA FROM ARGENTINA: SPECIES RICHNESS, DISTRIBUTION PATTERNS, AND AN EVALUATION OF ENDANGERED SPECIES Alejandra Rumi1*, Diego E. Gutiérrez Gregoric1, Verónica Núñez1, Inés I. César2, M. Andrea Roche3, Mónica P. Tassara3, Stella M. Martín2 & M. Fernanda López Armengol1 ABSTRACT Few studies have dealt with the geographic distribution of freshwater snails in Argentina. The objectives of this study were to: (1) determine species and family richness and diver- sity patterns; (2) verify if species richness behaves according to Rapoport’s rule; (3) iden- tify and classify species according to their distributions; and (4) identify endangered spe- cies. A grid was applied to a map of Argentina, with each of 340 squares (SUs) represent- ing 10,000 km2. A database of 3,376 records was analyzed. Of the 101 species belonging to ten families recorded in Argentina, four are introduced and 40 are endemic to Argentina. The Lithoglyphidae have the highest number of species (22). The highest species rich- ness/SU was recorded in the Brazilic subregion at Salto Grande (32 species) on Uruguay River, and parts of the Río de la Plata (31). In this subregion the species richness values increase from west to east. The highest richness in the Chilean-Patagonian subregion was detected at San Carlos de Bariloche, Río Negro province (9), and the Chilinidae contained the largest number of species. In Argentina, the north-south decline species pattern could be explained through Rapoport’s rule. In Patagonia, the species richness gradients do not show significant west-east trends. Most of the native species of freshwater molluscs of restricted distribution can be considered endangered (about 45 species) but need further study.

Cytologia 44: 385-389, 1979 The Chromosomes of Biomphalaria tenagophila (Gastropoda-Basommatophora-Planorbidae) R. O. Giacomozzi, Rita Riva and O. R. Vidal Laboratorio de Citogenetica, Facultad de Ciencias Exactas y Naturales, 1428 Buenos Aires, Argentina ReceivedSeptember 8, 1977 The subfamilies Bulininae and Biomphalariinae are of medical importance being potential intermediate hosts of human and herbivore schistosomiasis. South America is inhabited by the subfamilie Biomphalariinae. Biomphalaria glabrata (=Australorbis glabratus) is the principal host of Schis tosoma mansoni in Brazil. In Argentina there are no cases of schistosomiasis as yet although Biomphalaria tenagophila, of extensive distribution in this country, has proved to be also host (Rey 1956). Previously eight papers were devoted to the cytogenetics of the subfamily Biomphalariinae (Rangel 1951, Fraga and Goncalves 1956, Burch 1960 a, b, 1965, Natarajan et al. 1965, Narang 1974, Raghunathan 1976) but, excepting in the papers of Narang (1974) and Raghunathan (1976),karyotypes have not been shown. The aim of this research is to report the study of the meiotic and mitotic chromosomes of three populations of Biomphalaria tenagophila. Materials and methods Twenty nine specimens of Biomphalaria tenagophila (Spix 1827) were analyzed. The animals studied were colleted from the Botanical Garden of Buenos Aires and San Miguel de Tucuman in Argentina, and from Carrasco in Uruguay. Ident ification was made on the basis of the shell characteristics according to the descrip tion and figures presented by Paranse and Deslandes (1955). Chromosome preparations were made from ovotestis of adult animals and total body of young animals. The method applied was as follows: the material was placed in distilled water for hypotonic treatment for 20-30 min.
