Earthworm (Annelida: Clitellata) fauna of Chhattisgarh, India

Present communication is the first study on earthworm fauna of Chhattisgarh in central India. A total of nine species belonging to seven genera and five families—Moniligastridae, Eudrilidae, Lumbricidae, Megascolecidae, and Octochaetidae—were collected from different parts of the state. Among the families, Megascolecidae is most dominant with maximum number of species; other families are represented by a single species in each. The earthworm fauna of the state is comprised of both native (5 species) and exotic peregrine (4 species). A brief description, distribution and identification key for the recorded species is provided. Further surveys are required, which could lead to finding of more species.
