In 2014, researchers realized that a female bat collected near Kamali in 2012 was a member of this species.

Thomas obtained the specimens via Giacomo Doria of the Museo Civico di Storia Naturale.

[3] It is similar in appearance to the small-toothed long-eared bat, Nyctophilus microdon, with which it is sometimes confused.

Based on its large ears, however, it is hypothesized that it might hunt for insect prey using low-intensity echolocation.

It possibly captures prey by gleaning, which means plucking them off of a surface rather than aerial pursuit.

[5] The individual captured in 2012 was in a logged lowland rainforest of the Abau District of Papua New Guinea.
