Bogatstvo in raziskanost jugoslovanske faune: nižji nevretenčarji (Metazoa Invertebrata, ex. Insecta)

Approximately 3760 species from the discussed group are known from the Adriatic Sea, 4 could be endemic. Adriatic seems to harbour in fact 60—70% of all Mediterranean species. Approximately 5100 species and additional 1140 subspecies are known from continental habitats of Yugoslavia. Among terrestrial animals the richest are Aranea, Acarina, Gastropoda, among aquatic ones Rotatoria and Mollusca ; the highest number of known parasitic species are in Digenea. Aquatic Oligochaeta comprise 80% of the European inventory, a number of some other groups 40—60%. In Pseudoscorpiones, Prosobranchia, Amphipoda, 80—90 % are endemics and so are 45—70 % of taxa in 6 following groups ; the endemicity for the whole treated group is ca 25 %. The endemicity is nearly the same on the species and subspecies levels. The same is true for the percentage of troglobitic taxa, which is ca 20%. The Dinaride Region is far the richest in the world in the absolute number of stvgobiotic taxa ; this is even more prominent when counting the taxa density per area unit. The best explored has been Slovenia, the worst is Serbia. It seems, however, that Slovenian fauna is also in fact the richest part of Yugoslavia ; This can be explained by its great biogeographical heterogeneity. The generally low knowledge of the fauna in Yugoslavia (even in Slovenia) is an important obstacle for explorations, for which taxonomic and faunistic data are the base. For no one of the major groups an appropriate picture of the species distribution exists. The number of taxonomists is much to low, some groups are completely neglected.
