Wangkatja, Pindiini A102 and Wangkatha A12 are all 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. The WA Handbook, Glass (1990 p.c.) notes that the term Wangkatja is confusing, 'because all the Western Desert speaking Aborigines of the Eastern Goldfields and surrounding desert areas call themselves Wangkatja'.

Douglas (1990 p.c.) and Glass (1990 p.c.) point out that Wanggatha A12 from around Mt Margaret and Leonora is different to Wangkatja at Cundelee and Coonana.

Fasolo (2008) says that the Wangkatja people were known as the Nyanganyatjarra A17 people (also Puntutjarra people) because they used the word nyanganya ('this here'). However, Tindale lists Nagatadjara A17 as a separate group and locates it north-east of Wangkatja. In fact, it appears that Nyanganyatjarra is a sub-group of Wangkatja - Oates (1975:111), citing Glass and Hackett, says that Njanganjadjara A17 was originally at Mt Margaret, Wangkatja country, but its present location is north-east of Laverton.

Tindale's Pindiini may be the equivalent of Wangkatja or Wangkatha A12 - he lists Wanggada as an alternative name of Pindiini but it is treated as a separate dialect in this database on the basis of Tindale's distinct location for each of these. Between Pindiini A102 and Wangkatha, Tindale's map shows two other groups, Murunitja A8 and Tjeraridjal A7, but the validity of these groups is uncertain. Wangatha A12 or Wangkatja A103 may have been spoken there.

Fasolo (2008:1) notes that Cundeelee Wangka dialects have been referred to as Wangkatja. Hanson reports that speakers say Wangkatja is the same as Kuwarra A16 and that Kuwarra is also another name for Tjupan A31 (Wangka Maya Pilbara Aboriginal Language Centre 2008). According to Marmion (in Wangka Maya Pilbara Aboriginal Language Centre 2008), Wangkatja now refers to a speech variety spoken by Western Desert people around Laverton-Kalgoorlie.

The ABS treats Wangkatja as an alternative name of Wangkatha so Census data on Wangkatha may be relevant. Documentation on Wangkatha may also be relevant since the Thesaurus does not distinguish Wangkatja from Wangkatha. This database treats Wangkatja as a distinct variety, which is sometimes referred to as Cundeelee Wangka.
