The Indian state Telangana is located in the centre of the Deccan plateau and the western part of Eastern Ghats. It has varied agro-climatic and biogeographic features from plain to rocky terrain and hills. It has widely different types of forest that cover around 26,969.48 km2 of geographical area and include 12 protected areas of the state. This state is also endowed with rich floral and faunal diversity. The current publication reports about 2450 faunal species from the state. Among these 1744 species are invertebrates and 706 are vertebrates. A total of 68 faunal species are endemic to the state. The phylum Arthropoda has the highest number of species, comprising 52% species of the entire state fauna. The Amrabad and Kawal Tiger Reserves are hot spots of fauna in the state. The current work provides baseline information on the faunal diversity of the state, which could help in the preparation of strategies for better management and conservation of biodiversity of the state. However, the faunal documentation of each protected area and eco-sensitive zone still needs to be assessed which could provide a more accurate number of species in the state.
