Burnupia Explained

Burnupia is a genus of small freshwater snails or limpets, aquatic gastropod mollusks that are traditionally placed in the family Planorbidae.

However, according to the molecular markers (COI, 18S rRNA), the genus Burnupia differs from ancylids and from Planorboidea.^[1]

Distribution

This genus is generally confined to Africa and Brazil.^{[2] [1] [3]}

Species

The number of species in the genus Burnupia is highly uncertain and there are 21 specific names recognized.^{[2] [4]} Also in 2011 IUCN Red List there are recognized 21 species: 19 of them are Data Deficient, and Burnupia crassistriata and Burnupia stuhlmanni with Near Threatened status.^[5] There are probably "only few" species of Burnupia.^[2]

Species in the genus Burnupia include:

• Burnupia alta Pilsbry & Bequaert, 1927^[2]
• Burnupia brunnea Walker, 1924^[2]
• Burnupia caffra (Krauss, 1848) - type species^[2]

Ecology

Burnupia live in well-oxygenated freshwater habitats.^[2]
