Frans Janssens, Department of Biology, University of Antwerp, Antwerp, B-2020, Belgium

Abstract

A provisional edition of the checklist of Collembola (Hexapoda) from Belgium based on a literature survey is provided. The list includes the references to the original and several subsequent quotations for all 210 species from our country and a link to their distribution maps on a 10*10 km UTM grid. Missing maps will be provided as soon as possible.

Samenvatting

Preamble

This article is a translation and a revision of
Janssens, F. 1996. Nomina Collembola Belgica. Antwerpse Vereniging voor Entomologie, Entomo-Info, Jaargang 7, 1996, nr 3, p.79-90.
Since this first edition, 87 new species have been added to the list.

Contineously being revised.

100 years of Belgian Springtails research

This provisional edition is based on a literature survey and does not yet take into account all our own observations.
The following publications give a short overview of the history of 100 year of Belgian Collembola research : The current provisional list contains 210 species.

Systematic species list

A provisional edition of the checklist of Collembola (Hexapoda) from Belgium based on a literature survey is provided. The list includes the references to the original and several subsequent quotations for all 210 species from our country and a link to their distribution maps on a 10*10 km UTM grid. The checklist is a systematic list of valid taxon names with reference to the original authority, followed by the revision authority, if applicable. Each name follows the original orthography and mentions the original genus. The valid taxon names are ordered phylogenetically up to the rank of genus. The species valid names are ordered alphabethically within each genus. However, the references to the unidentified species are listed first. In each species, the references to the quotations are ordered chronologically, according to the traditional presentation of zoological catalogs (i.e. the name in this original spelling and combination; the cases of original invalid use of homonyms or incorrect spellings are indicated respectively by nec and sic). Synonyms, homonyms (cf. 'nec'), incorrect spellings (cf. 'sic') are ordered chronologically for each species. Whenever the original publication was verified, the page reference is mentioned following the publication date. (cf. 'yyyy:pp'; e.g. '1902:8'). In case the genus was not explicitly mentioned in the referenced publication, it is indicated by '...'. Publication dates are not always mentioned in such case.

A preliminary distribution map is provided for each species. The maps record the presence of all species in a 10 x 10 km UTM grid. Records published before 1950 are indicated with open white circle symbols, records published after 1950 are indicated with solid black circle symbols.
The maps are produced with the mapping module of the modular software package Inventar 1.3, intended to keep track of data collected by nature monitoring projects and data of collections of natural objects. Inventar is developed by Jan de Boer and it is distributed by Mistletoe Information, Maastricht, the Netherlands.
Click on the species name to open the associated species distribution map. Note that the available distribution data is rather sparse for most species and that several records can be added still.
