A single shell of M. unidentata was collected in the Parque Estadual Caverna do Diabo, southern São Paulo state, Brazil. Moreover, material of both species deposited at the Museum of Zoology of University of São Paulo were observed. These two seem to have allopatric distributions, and not overlapping. Mirinaba planidens occurs in the mountain ranges shared by São Paulo, Rio de Janeiro, and Minas Gerais in southeastern Brazil, whereas M. unidentata occurs in the chain of mountains in southern São Paulo and southern Brazil. The regions where these species occur are approximately 500 km distant from each other. Due to the similarity of the shells and their distributions, it is tempting to think about these species as examples of divergence by allopatric speciation.","PeriodicalId":50220,"journal":{"name":"Journal of Conchology","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2024-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141801134","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This population is located more than 450 km south of the previously known localities in Germany, and the species’ status as indigenous to France is therefore discussed. A review of palaeontological data show that the species has been recorded in eastern France during cold periods of the Middle and Lower Pleistocene. Furthermore, Lake Cerin is a small lake of glacial origin, located at an altitude of 766 m a.s.l., with little impact from human activities and inhabited by numerous threatened and protected boreo-alpine species. We postulate that this population indicates a wider past distribution, especially in the south, although we cannot exclude the hypothesis of a more recent introduction (natural or anthropic). We propose that G. riparius should be treated as a species native to France, as defined by the International Union for the Conservation of Nature, and targeted by a conservation and knowledge programme.","PeriodicalId":50220,"journal":{"name":"Journal of Conchology","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2024-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141818868","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We also expect that it will serve as a springboard, garnering more interest and enabling a new wave of studies on this fauna, which has one the highest extinction rates of all animal groups while being essential ecosystem functioning and also includes species of importance to public health and agriculture. We list all species of terrestrial gastropods that occur in the country, with information regarding synonymized names and fossils. We also propose a few nomenclatural acts to address some pending issues of easy resolution. A total of 748 species of terrestrial gastropods are known in Brazil, including 33 exotic species that have been introduced to Brazil. A total of 48 families are present, the majority of which belong to Stylommatophora; only six families represent the Neritimorpha, Caenogastropoda and Systellommatophora. The most speciose families are Bulimulidae, Strophocheilidae, Cyclodontinidae, Streptaxidae, and Simpulopsidae.

Analysis of the distribution of Vorticella aggregates on planispiral shells shows that the epibionts occur largely in the pseudo-cavities formed by the apex and umbilicus and mainly along the suture. This is the first case of ciliated epibionts on gastropods associated with temporary freshwater habitats inhabited by drought-adapted fauna.
