Nasal harmony in the Eastern Tukanoan languages (where Desano belongs) operates in a rather complex way, since suffixes can themselves be [+nasal] or [-nasal], as well as neutral "[0nasal]" with nasal and nonnasal allomorphs, in which case nasality or non-nasality spreads across morpheme boundaries. See the following article by Michael Kenstowicz, who describes the situation in Barasana:

Do you know if any Desano morphemes have nasal and non-nasal allomorphs? ...
