Type locality. Near Tricase Port, Lecce, Italy, 39.8829° N, 18.4055° E, ~ 70 m depth, occurring within zooidal and other cavities of host bryozoans.
Key features. Inception of ringed erect tubes is direct. The creeping portion of the colony is non-tubular, comprising smooth-walled expansions lacking zigzag sutures, within bryozoan zooids; the free pectocaulus is not adherent to the inner-wall of the creeping tube. Septa separating individual zooids were not found. Colonies extend only a few millimetres. Erect tubes with fusellar collars project up to 0.67 mm from bryozoan orifices and holes in dead bryozoan zooids. Fusellus height is 37±11 μm.
Comment. Like R. compacta, colonies of R. recondita are highly distinctive, as well as substratum-limited, and unlikely to be confused with any other species.
