Rapalai, Boikhutso Lerato, 2024, An annotated checklist of molluscs recorded from Botswana, Indago: Investigating nature and humanity in Africa (Oxford, England) 41 (10), pp. 15-44 : 24-25

Common name: Pond snails 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).
