Left lower molars in anterolabial view A1) showing carnassiform notches (arrows) in the cristids obliqua of m1–m2, and in occlusal view (A2, stereopair) showing accessory troughs (arrows) in m1–m3. B, C. Phoniscus papuensis (Dobson, 1878b) (AMNH 157475) from Papua New Guinea. B.

Left lower molars in occlusal view (stereopair) showing well-developed accessory troughs (arrows) in m1–m2.
