Male Deccan Large Fan-throated Lizard
Initially unsure of the identification (but see below). The tunnel is about 3 cm across. Noticeably flat appendages. I thought it could be Thrigmopoeus psychedelicus, described in 2014 by Sanap & Mirza. "A new iridescent tarantula of the genus Thrigmopoeus Pocock, 1899 from Western Ghats, India" Comptes Rendus Biologies 337 (2014) 480–486.
This name, Thrigmopoeus psychedelicus, does not appear to be in the species list within iNat (for now), and that is because the species is not valid, but rather a junior synonym of Haploclastus devamatha.
