Parthenina josae is a minute species of sea snail, a marine gastropod mollusc belonging to the family Pyramidellidae. These snails are known for their small size and often ectoparasitic or commensal lifestyles, typically associated with other marine invertebrates.

Description Parthenina josae is characterized by its very small, white, and often translucent shell. Like other members of the Pyramidellidae family, it possesses a distinctive protoconch (larval shell) that is typically heterostrophic, coiling in a direction opposite to that of the adult shell (teleoconch). The teleoconch is generally conoidal or turreted, and may be smooth or exhibit very fine sculpturing. Distinguishing features, such as the specific shape of the aperture, the presence or absence of a columellar fold, and the overall shell outline, are used by malacologists to differentiate P. josae from other species within its genus.
Distribution and habitat This species is known to occur in the marine waters surrounding the Cape Verde Islands in the eastern Atlantic Ocean. As a member of the Pyramidellidae, P. josae likely inhabits benthic environments, living on or near the seabed, often in close association with specific host organisms from which they derive nutrition.
Taxonomy Parthenina josae was formally described by the researchers A. Peñas and E. Rolán in 2017. The genus Parthenina itself was established by Bucquoy, Dautzenberg & Dollfus in 1884. The Pyramidellidae family is a large and diverse group of micromolluscs, with numerous species being endemic to specific geographical regions, often requiring detailed morphological study for accurate identification.
