Gastropods are a large and diverse taxonomic group, and South America has an impressive diversity of land snails. However, there are no accurate and complete lists or estimates of native species’ richness in South America. The aim of this work is to evaluate the use of iNaturalist in Argentina for terrestrial gastropods and its potential to contrib...

Descripción: Concha globosa, enroscamiento helicoidal dextrógiro (raramente levógiro) de 20-33 mm de longitud y 25-40 mm de diámetro mayor, formada por cuatro a cinco anfractos convexos. Espira corta; ombligo cerrado o ausente; abertura amplia y oblicua 18-20 mm de ancho que puede sellar con epifragma. Labio ligeramente engrosado y reflejado de col...

Bulimulus bonariensis is considered a species of relevance to agribusiness, having been declared a pest with indirect damage because of its negative effects on several crops such as soybeans, chickpeas, and corn in central and northern Argentina. The objective of this work was to analyze the growth pattern of a population born under laboratory cond...

Bulimulus bonariensis , a snail distributed over a large part of Argentina, has generated negative effects on the agribusiness. We accordingly conducted a seasonal sampling during 2018–2019 in order to characterize the gametic cycle and establish the size of this gastropod at gonadal maturity. Three reproductive stages were identified: the mature i...

Stylommatophora Orthalicoidea Bulimulidae Descripción: Caracol terrestre de tamaño mediano, la concha puede medir entre 31 y 37 mm de longitud, está formada por hasta 7 vueltas; la espira es cónica con suturas poco profundas; la abertura ocupa 1/2 de la longitud, es amplia y oblicua; el peristoma (borde externo de la abertura) es simple y en ejempl...

Gastropods of the genus Bulimulus Leach, 1814 have a neotropical native distribution and are considered large in size because they measure between 20.01-40.00mm. The majority of its species were originally described based on their most widely used set of characters, conchological morphology. In some cases, information about the morphology of hard p...

Cecilioides acicula (Müller, 1774), family Ferussaciidae, is native to the Palaearctic region but has been dispersed around the word by human activity. Here, we report the presence of this introduced species in La Plata city, Buenos Aires province, Argentina. This snail is largely subterranean and frequently is found in old graves in association wi...

Heleobia piscium (d'Orbigny, 1835), a member of the Cochliopidae family found only in South America, is distributed from Entre Ríos, Delta del Paraná, and the littoral of the Río de la Plata down as far as to Punta Indio (Buenos Aires), the southernmost limit of the snail's geographical distribution. To date, little information is available regardi...

The species of the genus Drepanotrema, most of them endemic to the Neotropical region, belong to the Planorbidae. Of the nine species of this genus, six are found in Argentina. The present investigation analysed the individual growth of Drepanotrema cimex in Arenalcito pond (34°11’ S, 58°15’ W), Martín García Island Natural Reserve of Multiple Uses...

The present study provides a list of freshwater molluscs species from the Davidson Stream in the Multiple Use Natural Reserve Guillermo Enrique Hudson, Florencio Varela, Buenos Aires, Argentina. In the survey performed in the months of March, April, and September 2009, 505 specimens were captured. Analysis of the taxocenosis of the molluscs of the...

The present work analyzes the population dynamics of Uncancylus concentricus in natural conditions in the northeastern coastal area of the Multiple Use Natural Reserve Isla Martín García (Beach of Basural), Buenos Aires, Argentina. Martín García Island is located in the Upper Río de La Plata, to the south of the mouth of the Uruguay River (34° 11'...
