An annotated checklist of Planorbinae (Heterobranchia, Hygrophila, Planorbidae) from northwestern Argentina

Abstract

The family Planorbidae comprises freshwater gastropods with planispiral, spiral and limpet-shaped shells. Subfamily Planorbinae sensu stricto, has a richness of almost 300 species, with some of the main genera being Biomphalaria Preston, 1910 and Drepanotrema Fischer & Crosse, 1880. Some Biomphalaria species are of concern to human health as they are intermediate hosts of blood flukes in Latin America. In Argentina, the family Planorbidae is represented by 15 species in four genera. In Northern Argentina (NOA region), records of the family are scarce, and most of them are a result of occasional collecting. We provide an updated checklist of Planorbinae in NOA resulting from fieldwork, material in malacological collections, and data in the literature. Nine species occur in the area: four species of Biomphalaria and five of Drepanotrema. Among Biomphalaria species, we recorded Biomphalaria straminea (Dunker, 1848), which is considered a natural host of the blood fluke Schistostoma mansoni Sambon, 1907, for first time in Salta province; the known geographic distribution of B. straminea is extended in the country.

“…The WHO has reported that approximately 770 million people are at risk of schistosomiasis, and it is spread over more than 78 countries in Africa, Asia, and Latin America, especially in poor communities (WHO 2022 ). Biomphalaria , Lanistes , Planorbarius , Neotricula , Oncomelania , Robertsiella , and Melanoides species of snails are responsible for acting as intermediate hosts for these blood flukes (Ovando and Marchi 2021 ; Saito 2022 ). The infective stage is either schistosomula or cercarial penetration on the skin (Anderson and Enabulele 2021 ; Li et al 2021 ; Limpanont et al 2020 ).…”

“…These parasitic diseases are major public health problems affecting over 15 million in the trans-national region of the Mekong River basin in Asian countries: Cambodia, Yunnan Province and Guangxi Zhuang of China, Lao, Myanmar, Thailand, and Vietnam (Sripa et al 2021 ). Snails of the Bithyniidae family have a major role in the transmission cycle as the first intermediate host, while fish act as the secondary/paratenic host (Charoensuk et al 2022 ; Ovando and Marchi 2021 ). There should be proper selection, handling, and treatment of food of aquatic origin before consumption, as consumption of undercooked fish is the main route of infection in humans.…”
