Contribution to the identification of Oligochaeta: Lumbricidae in the region of Annaba in eastern Algeria

Earthworms are the essential components of the biological soil community. Several species of Lumbricidae became model organisms for soil ecology, the biodiversity, the biogeography, the evolution of the contamination and toxicology. Our knowledge of the taxonomy, the ecology of earthworms and their distribution in Algeria are limited and known male. This preliminary study was conducted to try to identify the different species of earthworms that live in the region of Annaba in eastern Algeria. The samples were taken from four locations in the region of Annaba. At the end of the study, four species belonging to four genera were determined: Octodrilus complanatus, Nicodriluscaliginos uscaliginosus, Eisenia foetida, Allolobophora chlorotica
