Six mygalomorphs of the family Idiopidae and Theraphosidae are dealt with. The taxa, Heligmomerus Simon, H. barkudensis (Gravely, 1921), H. garoensis (Tikader, 1977) comb. nov. and Chilobrachys khasiensis (Tikader, 1977) are reported for the first time from the state of West Bengal and Chilobrachys stridulans (Wood Mason, 1877) from Arunachal Pradesh. All these rare and poorly known mygalomorphs are diagnosed and illustrated in the interest of Indian Arachnology.
