Data extracted for each article, author, institution, new species and specimen involved

Article
ZR ID number	Number attributed by the Zoological Record	ZR
Title		ZR
Abstract		ZR
Internet link	Internet link to the pdf article on the Zootaxa website	ZT
Number of pages	n = (ending page - beginning page) + 1	ZR + H
Delay of publication	Number of days between acceptance and publication	ZT + H
Category of document	Monograph; article	ZT
Category of work	We distinguished six categories of works. additional data: addition of sounds, karyotypes, redescriptions, chorology, phylogenies to the knowledge of a taxon, without new taxon description; checklists or catalogue of species/types; regional fauna: taxonomic revision at regional scale; taxonomic revision: each taxon or types reviewed, or at least 3 different kinds of analyses done (e.g. morphological studies plus distribution plus karyotype of a taxon); taxonomic work on isolated taxa: single or multiple descriptions of new taxa, new descriptions plus new records of the taxon; theoretical works: biographies or nomenclatural changes only, or theoretical work on taxonomy and nomenclature	H
Authorship presentation	Whether authorship is in alphabetical order or not. Names beginning by "De", "Van", are considered at letters "D" or "V".	H
Phylum delimitation	Phylum as provided by ZR indexation	ZR
Taxon delimitation	The most inclusive taxon treated in the article	H
Level of work	Level of the most inclusive taxon treated in the article. Species level: any level up to and including species level; genus level: any level from species level up to and including genus level; family level: any level from genus level up to and including family level; above family level: any level above family level	H
Geographic delimitation	The most single inclusive area treated in the article. We used political boundaries of studied areas instead of biogeographical ones, in order to study the relationship between laboratories and studied areas	H
Level of geographic delimitation	We used four levels of area: locality level, regional level, country level, major area level. We used other when the study involves more than one major area. Oceans and seas were treated as regions and affiliated to a country or a continent when specified in the article

Kind of specimen	Holotype, Syntype, Neotype, Paratype, Other specimen	H
Place of collect	Collecting locality as stated in the paper, with GPS coordinates if available. Localities were distinguished through their names or through their GPS coordinates. Each locality was referred to a country and a realm whenever possible. The geographical delimitations used are the same as for the publications	H
Institution of conservation	Institution where specimen(s) is/are kept	H
Year of collect		H

Sex	For holotypes only. Male; Female; Hermaphrodite; Unknown when the information is lacking. Because many authors do not indicate the sex when they use juveniles, we also added the category Juvenile	H
