Hypsugo vordermanni
French: Vespere de Vordermann / German: Vordermann-Zwergfledermaus / Spanish: Hypsugo de Vordermann
Other common names: \ White-winged Pipistrelle
Taxonomy. Vesperugo vordermanni Jentink, 1890,
Belitung Island, Indonesia.
Hypsugo vordermanni appears to be closely related to H. macrotis, to which it is morphologically very similar. Monotypic.
Distribution. NW, WC & S Borneo, and Banggi and Belitung Is.
Descriptive notes. Head-body 50 mm (type specimen), tail 13-7-15-1 mm (32 mm in type specimen), ear 8-0-13-3 mm, hindfoot 5-7 mm, forearm 30-5-33 mm; weight 4-5 g. Dorsal pelage of Vordermann’s Pipistrelle is reddish brown (bases of hair dark); ventral pelage is a little lighter. Ears are comparatively long, broad, and subtriangular, with broadly rounded tip; tragusis short, broad, and curved forward. Wing membranes are translucent white with brown tinge, and attach to base of toe. Tail extends a little past uropatagium, and calcar has distinctive but narrow lobe. Skull is small and rather broad (longer and larger than in the Big-eared Pipistrelle, Hypsugo macrotis); rostrum is short and premaxillae are shortened; braincase is rounded and inflated anteriorly, forming shallow frontal depression (almost evenly sloped); zygomatic arches are moderately developed with slight postorbital projection; basioccipital pits are deep and well developed. C' is slender and unicuspid; P* is minute and displaced inwardly, allowing C' and P* to touch; upperincisors are almost in a straight line; I* has a weakly defined second cusp; I’ is about two-thirds the height of I* and has weak lateral cusps; lower incisors are slightly imbricated; I, is slightly wider than I with I, even wider; and P, is about one-half the height and area of PP,
Habitat. Vordermann’s Pipistrelle may be restricted to coastal mangroves. Recorded in lowland regions from sea level to elevations of 100 m.
Food and Feeding. Vordermann’s Pipistrelle apparently trawls for small insects and maybe fish over coastal water bodies.
Breeding. No information.
Activity patterns. No information.
Movements, Home range and Social organization. No information.
Status and Conservation. Classified as Data Deficient on The IUCN Red List. Although virtually nothing is known regarding ecology and threats of Vordermann'’s Pipistrelle, it may be threatened by habitat loss due to mangrove harvesting and coastal development. Reported from Tanjung Puting and Bako national parks.
