In his new definition, subfamily contains six tribes Epomophorinae (Epomophorini, Myonycterini, Plerotini, Rousettini, Scotonycterini et Stenonycterini) instead of four initially recognized . Stenonycteris is recognized as a different kind of genre Rousettus and defined the new tribe Stenonycterini including one species, S . lanosus . This result suggests that echolocation in Pteropodidae was acquired independently in the genus Rousettus and gender Stenonycteris, probably related to their way of life cave, or that this character was lost in the common ancestor of the tribe of Epomophorini and Myonycterini probably due to the change of a way of life in forest cave .
Stenonycteris ni kutambuliwa kama aina mbalimbali ya Ghana Rousettus na hufafanuliwa mpya kabila Stenonycterini ikiwa ni pamoja na aina moja, S. lanosus. Hii inaonyesha kwamba matokeo echolocation katika Pteropodidae ilinunuliwa kwa kujitegemea katika jenasi Rousettus na jinsia Stenonycteris, pengine kuhusiana na njia yao ya maisha pango, au kwamba tabia hii alikuwa amepotea katika babu kawaida wa kabila la Epomophorini na Myonycterini pengine kutokana na mabadiliko ya njia ya maisha katika pango msitu.
