| Abstract | The 'Lentin & Williams Index', of which the first version was published in 1973, was intended to keep those involved in fossil dinoflagellate research abreast of the burgeoning taxonomic literature. An
additional role has been to 'tidy up' nomenclatural issues that have been left unresolved in publications. The printed Index has moved to an online database, DINOFLAJ, a new version of which is projected for 2016. Although since 2012 the
International Code of Nomenclature makes allowance for nomenclatural novelties to be proposed online, these digital sources need to be in PDF format in a recognised online publication. As DINOFLAJ3 will arguably not meet formal rules
of
nomenclature, this brief communication is intended to formalise nomenclatural changes that are needed before the database is released. Thus, the following names are herein validated: Alterbidinium compactum, Alterbidinium nuculum, Alterbidinium
ummiliforme, Alterbidinium pentangulare, Alterbidinium prominense, Alterbidinium pseudocirculum, Alterbidinium saltanovae, Alterbidinium simplex; and Palaecysta palmula subspecies ankamotraensis. Also proposed herein are the following new
combinations: Amphorulacysta delicata, Amphorulacysta? dodekovae, Amphorulacysta? expirata, Amphorulacysta metaelliptica, Amphorulacysta? monteilii; Bonetocardiella peregrinaensis; Cordosphaeridium gracile forma areolatum; Cribroperidinium graemei
subspecies trabeculosum; Dinopterygium asteriforme; Nyktericysta granorugosa, Nyktericysta pentaradiata; Palaecysta complicata, Palaecysta palmula, Palaecysta silyba; and Pithonella melloi. |
| Summary | (Plain Language Summary, not published)
Fossil dinoflagellates are a primary tool for determining ages and palaeoenvironments in Mesozoic-Cenozoic strata and thus a key to unravelling the
history of sedimentary basins and petroleum systems. To ensure effective use these fossils, a standard and consistent understanding of genus and species definitions (taxonomy) is critical. The Lentin and Williams Index is an internationally
acclaimed publication that has maintained such a standard over the years, and is now migrated to an online database known as DINOFLAJ, the third edition of which we will have ready to put online in early 2016. To keep the taxonomy up-to-date,
nomenclatural changes are required, but under the international rules of nomenclature, such changes are not valid if made in a database online. Hence we need to propose these changes in a conventional publication, and then we can use the new names
in DINOFLAJ. |
