The rare, enigmatic brachiopodVolborthia recurva (Kutorga) is redescribed based on new, well preserved collections from the Lower Ordovician (lower Llanvirn; Oeland Series; Kunda Stage) of Ingria (St. Petersburg district); it is also recorded for the first time from Sweden, where it occurs in the Kunda Stage on the Island of Oland.V. recurva has usually been classified questionably within the order Paterinida, but the shell structure, micro-ornamentation, muscle scars, and presence of a lingulid-type pedicle groove now indicate that it is an aberrant member of the lingulid family Elkaniidae; it is the only known lingulid with a high conical dorsal valve characterised by mixoperipheral growth.
