Looks like another typo in x86sets.py:

        Set("66, 0f, 3a, 61", ["VCMPESTRI"], [OPT.XMM, OPT.XMM128, OPT.IMM8], IFlag.MODRM_REQUIRED | IFlag._32BITS | IFlag.PRE_VEX)
        Set("66, 0f, 3a, 60", ["VPCMPESTRM"], [OPT.XMM, OPT.XMM128, OPT.IMM8], IFlag.MODRM_REQUIRED | IFlag._32BITS | IFlag.PRE_VEX)
        Set("66, 0f, 3a, 63", ["VPCMPISTRI"], [OPT.XMM, OPT.XMM128, OPT.IMM8], IFlag.MODRM_REQUIRED | IFlag._32BITS | IFlag.PRE_VEX)
        Set("66, 0f, 3a, 62", ["VPCMPISTRM"], [OPT.XMM, OPT.XMM128, OPT.IMM8], IFlag.MODRM_REQUIRED | IFlag._32BITS | IFlag.PRE_VEX)

That looks good now:
$ ./a.out c4 e3 79 61 d9 00
   1: (   0) c4e37961d900             VPCMPESTRI XMM3, XMM1, 0x0
