Saddle shape Clitellum Earthworm diversity in subtropical forest ecosystem was studied. Eight species belonging to six genera and four families were recorded. Among the four families megascolecidae was dominant at the study sites. Figure : Metaphire birmanica : A) Mature earthworm, B) Prostomium Ventral View, C) Prostomium Dorsal View and D) Clitellum (XIV-XVI) Diversity was high in natural reserve mixed forest with high canopy cover and epigeic, anecic and endogeic earthworms were found among which endogeic species (Pontoscolex corethrurus, Drawida sp. and Kanchuria sumerianus) are more versatile in spatial and temporal distribution in the study sites.
