This species is virtually identical in appearance to the Papuan pipistrelle (
P. papuanensis). In both species the dorsum fur is bicolored, with a brown tip overlying the longer black base of the hair. The ventral fur in both species has a black base tipped with cinnamon brown, and The snout, lip, ear, wing, forearm, and hind foot are clove brown, with a lightly furred uropatagium. However, there are several key morphological differences.
P. angulatus has a strongly concave forehead. The first upper incisor is bicuspid, and the height of the second upper incisor is less than the posterior cusp of this tooth. The
tragus narrows only slightly at the apex and the
antitragus is moderately high. ==Geographic range==
