Burnupia trapezoidea

27. Burnupia trapezoidea (O. Boettger, 1910) Distribution and year: Matopa Pan, Ngamiland N/A (Connolly 1939). Geographic range: Botswana, Namibia, South Africa. Habitat: Freshwater. Notes: The species occurs in sufficiently oxygenated waterbodies (Kristensen & Appleton 2010). De Kock and Wolmarans (2017) further mention the potential of the molluscs as an indicator of the freshwater ecosystem health. Type locality: “Witkop in British Bechuanaland near the German border”, Limpopo Province, South Africa (Boettger 1910). The type locality of this species seems erroneously attributed to Botswana (see Discussion for suggested correction). Sources: Connolly (1939: 517, as a subfossil); van Bruggen (1966 a: 109); Brown (1994: 177); de Kock & Wolmarans (2017: 260). Conservation status: Data Deficient. The species is possibly facing threat due to habitat loss and degradation (de Kock & Wolmarans 2017).
