Abstract

Two new species of Tetramorium Mayr, namely T. shivalikense sp. n. and T. triangulatum sp. n. are described. Tetramorium triangulatum sp. n. belongs to the inglebyi-species group and is described based on worker, queen and male caste, while T. shivalikense sp. n. belongs to the ciliatum-species group and is described based on worker caste only. Three species viz., T. caldarium (Roger), T. tonganum Mayr and T. urbanii Bolton represent first records from India. The male caste is described for the first time in the case of T. tonganum. Among these, T. caldarium is a tramp species which extends its limit to India as well. A revised key to the Indian ants of this genus is also provided herewith.
