Abstract:
In order to improve the biodiversity knowledge of Algerian springtails, a hundreds of samples were collected from many forests, caverns and caves meadow, in different bioclimatic stages during the years 2018-2020. 85 species and morpho-species were encountered in forest samples, spread over 15 families and 53 genera, which the mountain range of Jijel presents an exceptional biodiversity in endemic, rare and of biogeographical interest species. Among these species, 05 are probably new to science, Edoughnura sp., second species of the genus Edoughnura endemic to the Edough massif, Deutonura sp., close to Deutonura zana endemic to Edough and Collo mountains, Protanura sp., endemic to the Jijel massif, Tetracanthella sp., found exclusively in moss and Heteromurus sp., was collected from several forest stations in Jijel. 04 new species for Algeria and North Africa fauna appear in the list : Microgastrura duodecimoculata, Proctostephanus cf. cidi, Entomobrya marginata and Isotomurus sp2. 02 other species remarkable for their biogeographic status are present in the surveyed localities : Sensillanura austriaca endemic to the Northern Alps and the Collo massif and Kenyura sp., new species for science, belongs to the genus Kenyura, which all the species known to date are endemic to the tropical zone Afro-American. The statistical results obtained from the samples in the forest of Bouraoui Belhadef, reveal the presence of a great specific richness of taxonomic interest in the samples of rotten wood, litter and moss than the soil. 06 cave species not yet identified at the specific level, were harvested during the prospection of 04 caves in North-East Algeria. 03 species new to science belong to the same genus Orchesella and another species probably new to science of the genus Etomobrya, all were collected near the caves. Several interesting species are being identified and descripted, which allow us to expect new discoveries.
