Trabecula is a genus of very small sea snails, marine gastropod molluscs or micromolluscs in the family Pyramidellidae, the pyrams and their allies, and the subfamily Chrysallidinae, a large taxon of minute marine gastropods with an intorted protoconch.

Taxonomy

Dall & Bartsch (1904: 10) misinterpreted this genus and described it with “intercostal spaces crossed by equally spaced, raised spiral threads, sculpture reticulated”, despite that Monterosato (1884) wrote that there is no apparent spiral sculpture. This may explain why Dall & Bartsch (1909) described a new genus Salassiella with a type species extremely similar to that of Trabecula

General description

The whorls of the teleoconch are rounded, and longitudinally lamellose. The aperture is semicircular, with an exterior rib. There is no apparent spiral sculpture. The apex is retrorse. The columella lacks a fold or tooth.
