The total number of references in the present volume is 9,770. The references are given to primary sources of the genus-group and species-group names included in the Catalogue, and to works supporting the New Acts and other statements published in the present volume. No bibliographical reference is given to family-group names, these are in Bouchard et al. 2011. Names of all authors, if applicable, are given for each reference. An effort was put forth to unify the spellings of the names. For names that appeared in publications in two or more different orthographies, the one used in the Catalogue is that which was considered to be correct after thorough verification (e.g., the spelling Josef Müller for the author who also published as Giuseppe Müller). In such cases the alternative spelling or initial follows the original one in brackets. The original name is used for authors that subsequently adopted additional names, or honorary epithets (e.g., A. Semenov, and not A. Semenov-Tian-Shanskyi). Initials are given for all authors, even if they are missing in the original publication. Names published in two or more alternative spellings, that seem to be equally correct, are spelled following Schmitt et al. (1998). Citations of non-periodical literature published between 1758 and 1900, and given in the first edition of the Catalogue, were verified and when necessary completed and/or corrected following Bousquet (2016). Other important bibliographical information inducing changes in dates of issues and pagination, or clarifying data were published by Bousquet (2004, 2012), Evenhuis (2002, 2003, 2012), Fery & Hájek (2016), Kerzhner (1984), Poggi (2008) and Wheeler (1912). They are indicated by “DP” in square brackets at the end of respective citations in the chapter References.
Names in Cyrillic are transliterated as for any other Cyrillic text, unless an alternative spelling was preferred by the author, or the alternative name is generally used in the literature. It should be noted that lower case prepositions such as French “de” and German “von” are not given with the author’s name in the list of the taxa.
Titles of papers are given in full, i.e. not abbreviated, with subtitles, as originally published. Text written in Cyrillic is transliterated. Titles in languages using non-Latin or non-Cyrillic characters are translated into English and are presented in square brackets, followed by the indication of the original language in parentheses.
Titles of periodicals are given in full, but without eventual subtitles and in single language if bilingual. Series numbers are given in parentheses, and always precede the boldface volume number. The numbers of separate issues are provided when they are paginated separately, in which case they are in parentheses following the volume number. In other cases they are facultative. Unnumbered pages are indicated in square brackets. If descriptions appeared bilingual, the respective pages are separated by a slash. The titles of some periodicals vary over the years. For these periodicals the titles are given as they appeared for the respective items referred to (e.g., Coleopterologische Rundschau / Koleopterologische Rundschau). Contrarily, the journal Entomologische Blätter had several titles and subtitles during its existence. Since there is no danger of confusion with any other periodical, the journal is cited simply as Entomologische Blätter
The Annales de la Société Entomologique de France is one of the more important periodicals in the field of systematics. The title of its part “Bulletin” changed for more than 60 years, appearing usually as Bulletin des séances, Bulletin trimestriel or Bulletin entomologique. The bimensuel Bulletin des Séances de la Société Entomologique de France appeared as a parallel edition from 1873 to 1894. It remained unknown to most coleopterists, including some of the authors of the present Catalogue series. The work of Evenhuis (2002) and the on-line access to the edition were used to provide corrections in the present volume.
For ease of access, references of the same author and year were placed in order based on the first page number of the paper, with Roman numerals being placed last, with respect to the number of the respective issue. Books were placed first for a given year, unless a page range was cited, in which case the first-page rule was followed. Papers of the same year and with the same first page numbers were placed in order of their last page number. Thus the references are not arranged chronologically within each year.
