Excerpt from change request document:
Ethnologue currently lists "Ikarranggali" and "Kuku-Mini" as alternate names of Aghu Tharnggalu [ISO 639-3: ggr]. Australian language scholarship, however, points to the need to identify these as distinct languages.
AUSTLANG classifies Aghu-Tharnggala and Ikarranggal as distinct languages in the Rarmul Pama subgroup. Oates also recognizes these as two separate languages (1975: 287, 292).
AUSTLANG tentatively lists Gugu Mini, noting it is unclear if Gugu Mini refers to a specific language or is used as a broader cover term. Sommer says that Kuku Mini [AIATSIS Code Y94] literally means ‘speech good’ and is generally applied to languages and dialects of the Central Paman type (2008 p.c.). Gugu Mini and Aghu-Tharnggala are considered separate entities in Wurm (1972, 1994), Oates (1975), and Walsh (1981).
Dr. Claire Bowern identifies distinct locations for Aghu-Tharnggala and Gugu Mini in her map "Centroid Coordinates for Australian languages" (2011).
