Descripción de nuevas especies animales de la Península Ibérica e islas Baleares (1978-1994)tendencias taxonómicas y listado sistemático

Résumé

During the period 1978-1994 about 2.000 new animal species have been described in the Iberian Peninsula and the Balearic Islands. A complete list of these new species for 1978-1993, taxonomically arranged, and their bibliographic references is given in an appendix. Global trends in this process of biodiversity inventory demostrate a moderate but continuous increment in the number of taxa descriptions, as well as a higher contribution of Spanish authors. The number of articles published in journals listed by the Science Citation Index, and the use of the English language, are clearly growing. Most of the different phyla, classes or orders show an extreme variation in the number of described species per year, probably due to the small absolute number of publications. Insects clearly are the most studied group, but a certain decrease in its relative importance can be observed, related to the increase of studies on poorly known groups, such as nematodes.
