9. Aspatharia subreniformis (G.B. Sowerby II, 1867) View in CoL

Distribution and year: Thamalakane River, Maun [ANSP185375] 1984 ( Graf & Cummings 2023); Boro River, Okavango Delta 1973 ( Appleton 1979); Okavango Delta 2019 ( GBIF 2023 b); Okavango River,

3 km NW of Shakawe [NCSM35214] 2005 ( GBIF 2023 b); Savuti River in Chobe National Park 1984 ( GBIF 2023 b).

Geographic range: Angola, Botswana, Malawi, Mozambique, Namibia, Zambia, Zimbabwe.

Habitat: Freshwater.

Notes: The molluscs prefer mud sediments in slow flowing waters in major river systems across Southern Africa ( Van Damme 2018 a). It appears that Aspatharia spp. specimens from the Cunene and Okavango regions have inaccurately been identified as Aspatharia pfeifferiana ( Graf & Cummings 2006; Van Damme 2018 a). Here, all specimen records for A. pfeifferiana from Botswana have been included under A. subreniformis .

Type locality: Lake Nyassa, East Africa ( Sowerby II 1867) .

Sources: Appleton (1979: 164, as Aspatharia (Aspatharia) pfeifferiana ); Graf & Cummings (2006: 178; 2023); Appleton & Curtis (2007: 50, as A. (A.) pfeifferiana ); GBIF (2023 b).

Conservation status: Least Concern.
