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

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.
