The replacement name Sertularia laxa introduced by Allman (in legend of his pl. 26) for Sertularia exigua, is also threatened by Sertularia laxa Lamarck, 1816 [now recognized as a junior synonym of Thyroscyphus fruticosus (Esper, 1797) (Bedot, 1901: 471)]. According to Art. 57.2 of the ICZN (1999 edition), the junior primary homonyms are permanently invalid. So are the junior secondary homonyms under the rule of Art. 57.3.
