| Summary: | 47. Northern Pipistrelle Pipistrellus westralis French: Pipistrelle de Koopman / German: Mangroven-Zwergfledermaus / Spanish: Pipistrela Koopman Other common names: Koopman'’s Pipistrelle, Mangrove Pipistrelle, North-western Pipistrelle, Western Pipistrelle Taxonomy. Pipistrellus tenuis westralis Koopman, 1984, “Cape Bossut, (ca. 18°40’S, 121°30°E), Western Australia,” Australia. Pipistrellus westralis was originally described as a subspecies of P. tenuis but is considered a distinct species based on morphology. Although similar to one another, P. westralis and P. adams: are considered separate species based on morphological and genetic distinctions. Monotypic. Distribution. Along Australia’s N coastline from Cape Bossut in Western Australia to Karumba in W Queensland, including Melville, Bathurst, and some other offshore Is. Descriptive notes. Head-body 34-4-42-2 mm, tail 29-37-2 mm, ear 8-1-11 mm, forearm 27-4-31-3 mm; weight 2-7-4-8 g. Like the Forest Pipistrelle (P. adamsi), the Northern Pipistrelle is very small and one of the smallest bats in Australia. Dorsal pelage is dark brown; ventral pelage is buffy grayish brown. Muzzle, ears, and forearms are generally brown to light brown; wing membranes and uropatagium are dark brown. Ears are broadly triangular, with less rounded tips than in the Forest Pipistrelle; tragus is less than one-half the ear height, with small basal lobe and less convex posterior side than in the Forest Pipistrelle. Uropatagium stretches nearly to end oftail (only extreme tip free), and postcalcarial lobe is elongated. Glans penis is slightly flared, with central circular depression at tip that has many small fleshy spines. Baculum is shorter than in the Forest Pipistrelle, with wider base, and shaft is straight, with bifurcated tip (for 10% of its length rather than 30% in the Forest Pipistrelle). Skull is small and fragile; sagittal crest is absent; lambdoidal crest is weak; zygomatic arches are weak; I” is bicuspid, and I’ is unicuspid and subequal in height to second cusp of I?; ... |
