AbstractIncluded in this 2017 edition of the Lentin and Williams Index are all fossil dinoflagellate taxa at and below generic rank known to the authors as of 31st July 2016. The Index now has 667 generic and 4,464 specific 'correct' names, and includes in total 9,910 taxonomic entries in its main part (exclusive of appendices), as well as over 2,400 references. There are 728 entirely new taxonomic entries and 1,471 modified entries. Validly published and legitimate names are listed, as well as those that are effectively published, but are not valid or are illegitimate. Information on synonymies, nomenclatural types, nomenclatural status, history, and geologic age is also provided. The age cited for each taxon of species or infraspecific rank is, unless otherwise specified, that attributed to it in the protologue. It is not intended to be a full or up-to-date statement of the range of the species, and users are advised to consult the literature for potentially more detailed and precise information. Proposals include 5 new names (Bohaidina arenula, Bohaidina enodis, Parabohaidina arenata, Parabohaidina bulla and Parabohaidina runcinatus), all necessary because of the inadvertent creation of homonyms in the literature. Also proposed are two new combinations (Danea spinosa and Nyktericysta spinosa), made necessary by generic synonymys. Taxa at some time included in non-dinoflagellate or extant dinoflagellate genera are listed in two appendices. Appendix A lists all non-dinoflagellate genera that at some time have included species or infraspecific taxa now or previously considered dinoflagellates; it also includes genera listed in the main text of previous editions of the Index but not (now) considered dinoflagellates. Appendix B includes extant dinoflagellate genera based on motile types to which cyst taxa have been assigned. This edition of the Index is a digital publication and is released in parallel with a new version of the DINOFLAJ database, DINOFLAJ3 (
