Nomenclatural emendations of the family-group names Cylindrolepadinae, Stomatolepadinae, Chelolepadinae, Cryptolepadinae, and Tubicinellinae of Ross & Frick, 2007 — including current definitions of family-groups within the Coronuloidea (Cirripedia: Balanomorpha) Author Ross, Arnold Author Frick, Michael G. text Zootaxa 2011 3106 60 66 journal article 45935 10.5281/zenodo.201378 d3f93af5-fa4d-48f0-bf79-015d575bc62d 1175-5326 201378 Family Coronulidae Leach, 1817 (nom. transl. Newman & Ross, 1976 [ex Coronulidae Pilsbry, 1916 : 268 (synonymy) pro Coronulidea (sic) Leach, 1817 : 68]) Type genus. Coronula Lamarck, 1802 : 464 ; by original designation of Leach (1817: 68) . Diagnosis. Wall six-plated (R-CL1-CL2-C), relatively thick, mono-lamellar, or bi-lamellar when T-shaped flanges and longitudinal canals present; parietes without mid-rib; opercular plates reduced, tergum vestigial or absent, or tergum and scutum absent; apertural hood present. Remarks. Leach (1817) included Tubicinella , Coronula and Chelonibia when he proposed this family, but did not specify the type genus. Since Coronula was the nominal genus upon which the family-group was based, it becomes, ipso facto , the type by original designation. Chelonibia has since been relegated to the Chelonibiidae . The Coronulidae is now recognized as including four subfamilies, the Coronulinae Leach, 1817 , Cryptolepadinae subfam ., nov . Tubicinellinae subfam. nov. and Xenobalaninae Gruvel, 1905 .
