Jordana R, Baquero E. A proposal of characters for taxonomic identification of Entomobrya species (Collembola, Entomobryomorpha), with description of a new species. Abh Ber Nat kd mus Görlitz 2005;76(2):117-134.
The species of the genus Entomobrya have bean traditionally identified using colouration. Only
some authors have considered a small number of morphological characters, in badly mounted or old
specimens, as well as chaetotaxical characters (but not used for species identification). The study of a
large series of slides from extensive collections of Entomobrya species with observation of the complete
chaetotaxy has demonstrated that specimens with the same colour pattern can have a very different
chaetotaxy, which is related with the geographical origin. On the other hand, specimens with similar
chaetotaxy but from distant geographical areas maintain the same colour pattern. The present paper
proposes a set of both morphological and chaetotaxical characters as a useful tool for the species
identification in the genus Entomobrya in connection with the observation of colour pattern. For the
selection of this set of characters more than 500 slides from the top-ranking European museums have
been studied. Two species of the genus with similar colour pattern but with a different chaetotaxy are
used as models for the methodology: E. nivalis (Linnaeus, 1758) and a new species from León (Spain)."By kind permission of Senckenberg Museum für Naturkunde Görlitz; copyright by Senckenberg Görlitz. See also: www.soil-organisms.org"
