Pindiini, Wangkatja A103 and Wangkatha A12 are listed as separate dialects of the Western Desert language A80 in this database but they appear to be very close to each other and hardly distinguishable. Pindiini may be an alternative name of Wangkatja A103 or Wangkatha A12.
However, on the basis of the distinct location given by Tindale (1974), it is treated as a separate dialect; Tindale lists Wanggada as an alternative name of Pindiini. Between Pindiini and Wangkatha/Wangkatja, Tindale's map shows two other groups, Murunitja A8 and Tjeraridjal A7.
The ABS treats Pindiini and Wangkatja as alternative names of Wangkatha so census information on Wangkatha may be relevant to Pindiini and Wangkatja. Documentation on Wangkatha A12 may be relevant.
