“…Although L. fulica has small genetic variability where it was introduced, as in South America [63], its generalist behavior allows the species to occupy a wide distribution. On the other hand, Megalobulimus species occur in more restricted geographical distributions [25,35,36,64,65] and have more specific habits [31][32][33][34]63,66], which makes their niche breadth more specialized.…”

“…It is endemic to South America, with some introductions to the Caribbean Islands [25,28,29]. They are nocturnal, burying themselves in the litter during the day, or during periods of hibernation or aestivation [25,30,31]. Megalobulimus activity is very seasonal [32,33], occurring in low densities [34], and they also have low reproductive potential, with an annual production of up to nine eggs [33].…”

Climate change and invasive species are critical factors affecting native land snail diversity. In South America, the introduced Giant African Snail (Lissachatina fulica) has spread significantly in recent decades into the habitat of the threatened native giant snails of the genus Megalobulimus. We applied species distribution modeling (SDM), using the maximum entropy method (Maxent) and environmental niche analysis, to understand the ecological relationships between these species in a climate change scenario. We compiled a dataset of occurrences of L. fulica and 10 Megalobulimus species in South America and predicted the distribution of the species in current and future scenarios (2040–2060). We found that L. fulica has a broader environmental niche and potential distribution than the South American Megalobulimus species. The distribution of six Megalobulimus species will have their suitable areas decreased, whereas the distribution of the invasive species L. fulica will not change significantly in the near future. A correlation between the spread of L. fulica and the decline of native Megalobulimus species in South America was found due to habitat alteration from climate change, but this relationship does not seem to be related to a robust competitive interaction between the invasive and native species.

“…Megalobulimus spp. are herbivores and typically occur in low densities, living in forest litter and soil and being active in the night or immediately after rain (oliveiRa et al 1984, Fontenelle & miRanda 2017, miRanda et al 2015, 2020, miRanda & coRReia 2021. Their large size inevitably meant that they would be used for human consumption, both for the first peoples of South America, as well as by later migrants (e.g., maRtenS 1876, valduga 1985, aRauJo et al 2012, RamíRez et al 2012.…”

A new species of Megalobulimus from the early Holocene of southeastern Brazil (Gastropoda: Strophocheilidae)

A new species of megasnail, Megalobulimus diluvianus sp. nov., is herein described based on subfossil material from limestone caves in the area of Lagoa Santa, Minas Gerais state, southeastern Brazil. The specimens come from a context of archaeological strata of early Holocene age. Considering the morphological features of the shell, the new species seems closely allied to the so-called “Megalobulimus bronni complex”, whose representatives inhabit the tropical to subtropical Atlantic plateau of southeastern Brazil. Megalobulimus diluvianus sp. nov. is considered to be presently extinct (substituted by M. oblongus in the stratigraphical record).
