31. Racey’s Pipistrelle Pipistrellus raceyi French: Pipistrelle de Racey / German: Racey-Zwergfledermaus / Spanish: Pipistrela de Racey Other common names: Racey's Pipistrelle Bat Taxonomy. Pipistrellus raceyi Bates et al., 2006, “Kianjavato, Province de Fianarantsoa, Madagascar, 21°22.84°S, 47°51.96’E, 75 m asl.” Relationship of P. raceyi to other species of Pipisitrellus is uncertain because it seems to be highly divergent from other species. As currently defined, western and eastern populations of P. racey: might represent completely distinct species or subspecies based on limited genetic and morphological data. Monotypic. Distribution. Lowlands of W & E coasts of Madagascar. Descriptive notes. Head-body 46-52 mm,tail 229-34 mm, ear 7-5-11 mm, hindfoot 5-3-7-5 mm, forearm 27-33 mm; weight 3-8-5-8 g. Eastern population has generally larger individuals than western population. Pelage is relatively long. Dorsum of Racey’s Pipistrelle is light rufous, with distinctly darker head; venter is buffy brown. Wing membranes are dark brownish black, and uropatagium is a similar color and stretches to about end oftail. Muzzle is relatively short and inflated, with large glandular swellings that are essentially naked; face is pinkish and darker blackish brown closer to front of muzzle. Ears are uniformly dark brownish black and short, with rounded tips and 3-5 well-developed ridges; tragus is ¢.50% the height of ear, crescent-shaped, and has small notch near base of posterior border and rounded tip. Penis is very long (9-6-11-8 mm; much longer than the Dusky Pipistrelle, P. hesperidus, in Madagascar). Baculum is long and thin, curving upward near base and downward near tip; tip is always bifurcated, and base is bifurcated in western population and not in eastern population (only with very slight medial notch); base is either relatively skinny in western population but inflated dorsally in eastern population. Rostrum is rounded and flattened, with slightly upturned tip; supraorbital ridges are inflated and angular, ...
