The poorly known type species of Lingulella, Lingula davisii MCoy, 1851b, is redefined from new material collected from the type locality and horizon (Upper Cambrian, North Wales). Lingulella is similar to Obolus and to Ungula in its musculature, mantle canals, and pseudointerareas, but has a thinner shell and irregular pits over its internal surface, concentrated in the visceral areas. A dissolution method that can facilitate the study of lingulate brachiopods preserved in clastic lithologies is described, and its wider adoption is recommended in order to reveal diagnostic morphological characters.
