Biologie Résumé : Several months of prospecting in the forest of Collo allowed us to perform a series of samples in various edaphic environments in order to enrich our knowledge about soil fauna. The results show an exceptional richness in endemic rare species having a large taxonomic and biogeographic interest. Seventy-one species are identified, of which four are new to science and are described in this work and published. Three of the four new species belong to the same genus: Pseudachorutes deficiens, Pseudachorutes labiatus and Pseudachorutes octosensillatus (neanuridae, Pseudachorutinae.). The fourth new species belongs to the genus Deutonura: Deutonura zana (Collembola:neanuridae: Neanurinae) second species of the same genus in Algeria. This species was collected in Edough and more recently in Collo. Our study reveals the existence of cryptic diversity (not apparent morphologically) between populations of Edough and Collo. This genetic divergence is revealed by the sequencing of the mitochondrial gene COI. This is a case in Neanurinae. Several unidentified species are listed in morphospecies or sp. They are in number of 16, representing 22% of the total number of harvested species. Regarding biogeographical membership of harvested wildlife, 45% of species are widely distributed, 16% are rare or possibly endemic species. One of the original features of this work is the presence of an endemic species (Sensillanura austriaca) from the north’s Alpes so far. The wealth of the massif Neanuridae is much higher than most of other Mediterranean regions (excluding Corsica) sampled significantly. Diversity index indicate that Oued Z'hor is the richest of the four areas surveyed. There is a significant difference in species composition between localities, indicating that according to geographical origin, the same habitat does not present the same specific composition. The result of the comparison of the diversity of the Collembola of the Collo massif to those of the bulk of the Edough shows that there are significant dissimilarities in the faunal composition (33 common species between Collo and Edough). Cases of clear vicariances were detected, the most remarkable one between Edoughnura sp., from Collo and the endemic species of the same kind Edoughnura rara from Edough (Deharveng & KrouaHamra, 2007). The second case is an intraspecific level of a genetic divergence between populations of Deutonura zana of the two massifs. This cryptic diversity suggests that a parapatric area may exist in the north of Azzaba.

Biologie Résumé : Several hundreds of samples taken in seven localities of the Algerian NorthEast are analyzed. The taxonomic study on the level of the species reveals the presence of a total of 113 species of Collembola. The inventory of the country in Collembola is enriched by a contribution by 56 new species, of which 49 are announced here for the first time in North Africa. The majority of the species lately announced in Algeria are also new for North Africa, which shows that a East Algerian fauna quite different from that of the surrounding countries, in particular of Morocco which was studied the most. Fauna met is composed of species belonging to the four orders of known Collembola, 15 families and 55 genera. The prevalence of the Poduromorpha order with 57 species and 26 genera constitutes a remarkable character of the fauna of Collembola. Inside this group, the family emerges from Neanuridae which is represented by 27 species belonging to 3 subfamilies. One of them, Frieseinae with 11 species of the same genera (Friesea) constitutes the other original character of the collembolan fauna. Among the seven prospected localities, it is mountainous massif of Edough that the essence of the total collected and identified species comes, that is to say 78 species. The most unexpected character of this fauna is the diversity of the Friesea genera (8 species) and Hypogastrura genera of the astonishing richness specific of Neanuridae met in the massif of Edough: 19 species against only 10 in the remainder of the country. What makes it distinguish from all the Mediterranean forested mountains vaster and more intensely studied. Four new species are described: Deutonura n.sp.zana, Friesea n.sp.major, Friesea n.sp.algirica and Friesea laouina, of which is published, (Deharveng & Hamra-Kroua, 2004). Twenty two species are rare, are listed with comments on their taxonomic position, and makes it possible to expect new discoveries. Affinities of the settlement of Collembola are primarily with Mediterranean fauna. The fauna of Edough consists of some European elements and circumméditerranéen. The dynamics of the settlement of Collembola endogens is determined by the seasonal variation of the fundamental edaphic factors: temperature and moisture .Their seasonal, obvious impact surfaces some, feels even in the in-depth ground.

Biologie Résumé : Dozens of samples from five localities of Northeastern Algeria are analyzed in the laboratory of Biosystematics and ecology of arthropods. A total of more than 27311 individuals were extracted following the use of common extraction springtails techniques. The taxonomic study of the species reveals the presence of a total of 49 species of Collembola Poduromorpha. Our findings have enriched the national heritage Collembola by a contribution of 9 new species for the country one of them is new to science. All the new species for the country are also new to North Africa, which shows that the North-eastern Algeria has a very different fauna from that of neighboring countries in the Mediterranean circum. The fauna which concerns by this study consists of species belonging to three super-families, 5 families, 4 subfamilies and 27 genera of the order Poduromorpha. Inside Poduromorpha, stands the family Neanuridae with 22 species belonging to 3 subfamilies known six subfamilies: Frieseinae with 6 species of the same genus (Friesea); Neanurinae with 9 species and 5 genera and finally the exception subfamily Pseudachorutinae with 7 species and 6 genera. Among the five prospected localities is the mountainous massif of Edough that comes the most of the total species collected and identified, that is to say 44 species. The most unexpected character of this fauna is the presence of endemic species hitherto distant biogeographically regions: the case of genres Kenyura and Cephalachorutes known only in African’s American’s tropics. Guelma region reveals exceptional on the map of specific diversity: in addition to the new species (Superodontella tayaensis sp.nov.). The locality also hosts Kenyura sp. Cephalachorutes and minimus. Diversity of Friesea genera (6 species) and the astonishing richness specific of Neanuridae met in the massif of Edough: 19 species against only 10 in the rest of the country. What makes it distinguish from all the Mediterranean forested mountains vaster and more intensely studied. Five new species are reported here: Superodontella tayaensis n.sp, Friesea major, Deutonura ns Edoughnura rara, Edoughnura sp2. Three had been described before this work and one is described here: Superodontella tayaensis (Arbea, Brahim Bounab & Hamra kroua 2013). Eight species are rare, which makes it possible to expect new discoveries. The affinities of the population of Collembola are primarily with the Mediterranean fauna, with original features. The fauna of Edough consists of some European elements that Guelma is rather unusual, unexpected and original.
