Chrysallida maoria is a species of small marine gastropod mollusk belonging to the family Pyramidellidae. The species was formally described in 1940 by the New Zealand malacologist Arthur William Baden Powell. In contemporary taxonomic databases, such as the World Register of Marine Species (WoRMS), the species is often classified under the genus Linopyrga, making Chrysallida maoria a secondary synonym for Linopyrga maoria.
The species is endemic to the marine waters of New Zealand. Like other members of the family Pyramidellidae, Chrysallida maoria is a micromollusk, characterized by its minute shell size. The Pyramidellidae family is known for its ectoparasitic behavior; these snails typically lack a radula and instead possess a long, retractable proboscis equipped with a piercing stylet. This anatomical feature allows them to feed on the body fluids of various hosts, including other mollusks and polychaete worms.
The shell of Chrysallida maoria generally follows the family's typical morphology, often featuring a turreted or conical shape with distinct sculptural elements, though specific visual descriptions are primarily limited to specialized malacological literature. Accurate information regarding the species' precise depth distribution, specific host preferences, and reproductive biology is not confirmed.
