Monograph; article

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

Whether authorship is in alphabetical order or not. Names beginning by "De", "Van", are considered at letters "D" or "V".

Phylum as provided by ZR indexation

The most inclusive taxon treated in the article

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

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

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

Authors

List of the articles written by the author in Zootaxa

Institution of the author for the paper concerned. The ZR provides the address of the first co-author; the other ones were added from the paper itself. Whenever the author is affiliated to several institutions, this information was retained

Some email addresses were provided by the ZR; others were found in the article

Amateur, Doctoral student, Established taxonomist researcher, Established non-taxonomist researcher, Master student, Postdoctoral, Retired researcher, Technician

Country of birth

Master (four or five years of faculty), PhD (or equivalent), Other, No degree

Institutions

The names of all institutions were checked to suppress duplicates

Five categories of institutions were recognized: Museum, University, Institute, Private, Other institution

The affiliation of a country to a major area followed the CIA World Factbook data [34]

Some institutions are subordinate to others, which may (or may not) appear in the address given by the author(s). For each of them, the following information was checked using their web sites:

1: whether the institution is autonomous

2: whether it is subordinate to another institution

3: whether it is subordinate to two other institutions

Name of the superordinate institution if relevant

New species

List of the specimens involved

Whether allotypes are designated or not

Whether numerous developmental stages are involved or not

Parsimony, Bayesian/maximum likelihood, Distance, Combined methods

Morpho-anatomical, Molecular, Bio-acoustic, Karyological, Other

Specimens used to describe a new species

Number of specimens of each type for each new species

Holotype, Syntype, Neotype, Paratype, Other specimen

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

Institution where specimen(s) is/are kept

For holotypes only

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
