* endemic species

Pocock (1900) listed records of H. tamulus (as Buthus tamulus ) in India, from Sind in the Northwest and Dehra Dun throughout the whole of Western, Central, and Madura in Southern India and specifically noted the absence of this species in Burma and Ceylon. There is a possibility of introduction of this species to Jaffna from India by movement of goods during IPKF (Indian Peace Keeping Force) occupation in Sri Lanka between 1987 and 1990 or during the 30-year long civil war in northern and eastern regions of the country or through transportation of goods between India and Sri Lanka. Since there is a continuous coastal line around the country and increased transportation in between the northern part and the south of Sri Lanka, there is a risk of spreading this species to the other parts (especially the coastal districts) of the island.
