The genus "Corbicula" includes 16 species described to date. By 1802 William Kirby had introduced the New Latin term "corbicula" into English. Additionally, the fringed hair of its hind legs forms the corbicula, or pollen basket. Brazilian habitats have been found to have support the largest abundances of invasive "Corbicula" spp. This species is distinct from, but often confused with, the rather similar species "Corbicula fluminea". The fauna has an interglacial aspect, and includes Corbicula fluminalis and Pisidium clessini. The second edition, 1777, refers to the corbicula simply as the "basket". The names themselves are similar in the literature (e.g. by being called ""Corbicula fluminata""). The freshwater clam "Corbicula australis" (little basket shell) is found in rivers in the ACT. Elachista corbicula is a moth of the family Elachistidae that is found in Australia. The best known is "Corbicula fluminea", an invasive species in many areas of the world. "Corbicula" is a diminutive of "corbis", a basket or pannier.
