Pajaud (1966: 70) established the new genus name Danella to accommodate the new brachiopod species D. fragilis from the Late Cretaceous of France. The name is still in use ( IRMNG, 2021). However, Gray (1869: 124) had introduced an identical genus name in the Cnidaria, currently considered a subjective synonym of Sinularia May, 1898: 101 (WoRMS, 2021) . Regardless of the current rank of Danella Gray , it remains a senior homonym of Danella Pajaud and the latter name needs to be replaced, lacking available synonyms (ICZN, 1999, Arts. 60.1, 60.2). We propose Thecidanella Ceccolini & Cianferoni nom. nov.

Etymology. The new name refers to the order to which the genus is assigned, adding the prefix Theci- (the first part of the word Thecideida ) to the original name. Feminine gender.
