Andersen's long-tongued fruit bat (<M. sobrinus>) was named by Andersen (1911) based on the specimens of Gunong Igari, Malaysia. It was originally considered to be a subspecies of the small long-tongued fruit bat (<M. m. sobrinus>). However, Medway (1969) believed that Andersen's long-tongued fruit bat is significantly larger than the small long-tongued fruit bat, and the two should be different species.
