Diagnosis
ReferenceDiagnosis
E. D. Gill 1951Convexi-concave rafinesquid brachiopods with valves geniculated anteriorly and laterally, the dorsal valve being the more strongly geniculated. Ventral valve with tongue on anterior margin, and dorsal valve with accommodating recess. Ornamentation radially multistriate with concentric wrinkles on both the posterior and the geniculated parts of the valves. Ventral valve with high, smooth palintrope, while that of the dorsal valve is linear. Ventral and dorsal muscle fields of leptaenid type, with associated marginal ridges. Large bilobed cardinal process. The new genus is readily recognized by the presence of the tongue (die Zunge of the German literature).
