“…Here, it is also recorded from the Corrientes Province (Argentina). The record for Santa Fe Province (Miquel & Parent, 1996) was erroneous (Salvador, 2021); the image of the specimen does not resemble G. iheringi but to an indeterminate species of Gastrocopta. Mentions of G. iheringi from Peru (Ramírez et al, 2003) and Venezuela (Thompson & López, 1996) need to be confirmed.…”

The species of Gastrocopta here described share the angular lamella united with the parietal lamella at the inner end of the former, giving the shape of a "Y". We describe two new species inhabiting the central and northern part of Argentina, and we report G. iheringi (Suter, 1900), which has the same structural feature, for the first time in the country. Present species of Gastrocopta live in Argentine temperate and tropical areas, but previous records indicate that the most ancient fossil record with such a characteristic anguloparietal lamella is from the Early Miocene of Santa Cruz Province (southern Patagonia).

The catalogued collection of South American terrestrial gastropods, including the Caribbean ABC islands and Trinidad & Tobago, of the Auckland War Memorial Museum (AM), New Zealand, is discussed here. In total, 264 specimen lots from South America were found in the AM collection, including eight type lots. Twelve of the specimens represent new geographic distribution data, including the first known precise locality for the species Bostryx luridus (L. Pfeiffer, 1863) and potentially for Drymaeus cf. waldoschmidti Parodiz, 1962 as well. The specimens of Lopesianus crenulatus Weyrauch, 1967 allowed for the revision of the monospecific genus Lopesianus Weyrauch, 1958, which is herein considered valid in the family Simpulopsidae.

The genus Radiodiscus includes minute terrestrial snails occurring throughout the American continent. We assessed the conservation status of eight poorly known Chilean Radiodiscus species using the International Union for Conservation of Nature (IUCN) and NatureServe categories and criteria. Under the IUCN guidelines the species were assessed using the Criterion B of geographic range, which considers the extent of occurrence (EOO) and area of occupancy (AOO) as subcriteria. For NatureServe we used these two parameters plus the number of occurrences, ecological viability, and threats. Considering species rarity and possible sampling bias, we also used ecological niche modeling to determine climate and environmental tolerances and predict potential species distributions analyzing bioclimatic and geographical layers. Radiodiscus australis, R. coarctatus and R. quillajicola were listed as Critically Endangered by IUCN and NatureServe standards; R. coppingeri, R. flammulatus, R. magellanicus and R. villarricensis as Endangered by both methods; while R. riochicoensis as Endangered by IUCN standards and Vulnerable by NatureServe standards. Niche modeling results indicated that Radiodiscus species respond to different environmental conditions and that the predicted distribution areas contain suitable habitats beyond the current ranges, which may be helpful for future management plans. Nature-based sport tourism, forestry activities, urbanization, roads, pollution, mining, forest fires, livestock, volcanism, tsunamis, soil erosion and introduced species are among the major threats affecting these snails. Based on the low number of occurrences and the threats identified, the most at-risk species are R. coarctatus and R. quillajicola (one record), R. australis (two records) and R. villarricensis (three records); the latter two lacking occurrences within protected areas. Compiling our findings, we propose a list of actions to preserve Chilean Radiodiscus species.
