E16/E17/E18/E19 has two entries
|Mapidian [mpw]||Mawayana [mzx]|
|Alternate names||Mahuayana, Maiopitian, Maopityan, Mawayana||Mahuayana|
|Population||50 in Brazil (1986 Howard)||50 (1986 C. Howard)|
Not surprisingly, the two entries refer to the same group ( Howard, Catherine Vaughan 2001 ), as comparison of data from both ethnonyms confirms ( William C. Farabee 1918 , Eithne B. Carlin 2006 ). See also: Mapidian-Mawayana [mpw].
