Abstract

Two new species of Indothele Coyle, 1995 are described from the Western Ghats of India: I. amboli Kadam, Tripathi & Sherwood sp. nov. (♂♀) from Amboli in Maharashtra, and I. silentvalley Tripathi, Kadam & Sherwood sp. nov. (♂♀) from Silent Valley National Park in Kerala. Images of the type material of I. dumicola (Pocock, 1900), the type species, are presented to complement its identification. Additionally, the male of I. mala Coyle, 1995 is described for the first time. We transfer the misplaced Ischnothele indicola Tikader, 1969 to the genus Macrothele Ausserer, 1871 (Macrothelidae), creating the new combination Macrothele indicola comb. nov. A catalogue of Indian Ischnothelidae and their currently known distribution is mapped.
