Chrysallida is a speciose genus of minute sea snails, pyramidellid gastropod mollusks or micromollusks in the family Pyramidellidae within the tribe Chrysallidini.

The genus Chrysallida Carpenter, 1856 has been used as a catchall, particularly in the European literature following a lead by Winckworth (1932), for most pyramidellids having both axial and spiral sculpture but having otherwise little in common with the Californian type species C. communis (C. B. Adams, 1852).

A statement that this is incorrect was voiced by van Aartsen, Gittenberger & Goud (2000: 21) who nevertheless still used Chrysallida as the genus to include many Eastern Atlantic species, distributed into several subgenera.

This move was continued by Høisæter (2014), Peñas, Rolán & Swinnen (2014) and Giannuzzi-Savelli et al. (2014) who are here followed, but there are still many species remaining unduly under Chrysallida.

[5] Species within the genus Chrysallida are commonly distributed in all oceans from the tropics to the polar regions, the Arctic and the Antarctic.
