34. Endo’s Pipistrelle Pipistrellus endoi French: Pipistrelle d'Endo / German: Endo-Zwergfledermaus / Spanish: Pipistrela de Endo Taxonomy. Pipistrellus endoi Imaizumi, 1959, Horobe, Ashiro-cho, Ninohe-Gun, Iwate Prefecture, Honshu, Japan. Relationship of P. endoi to other species of Pipistrellus is uncertain, but it seems to be similar to P. abramus. Monotypic. Distribution. Honshu and Shikoku Is, Japan. Descriptive notes. Head-body 40-49-5 mm, tall 28-38-53 mm, ear 10-12-5 mm, hindfoot 6-5—-8-2 mm, forearm 29-8-34-2 mm; weight 5-6-8-7 g. Pelage of Endo’s Pipistrelle is woolly, slightly curled, and buffy. Dorsum is glossy reddish brown; venter is lighter brown. Ears and membranes are blackish brown. Ventral fur extends to line joining knee and basal one-third of humerus on wing membrane. Upper surface of uropatagium is furred nearly to middle. Nostrils are naked, and internarial septum is broad. Calcar is long, and uropatagium extends nearly to end oftail (only last millimeter oftail is free). Baculum is relatively long and slightly curved, with straight line length of 9-10 mm. Skull is small, robust, and heavily built; zygomatic width is comparatively wide; muzzle is short; braincase is swollen laterally; postorbital process is weakly developed; both upper incisors are bicuspid; P? is higher than cingulum of C! and within tooth row; P* is well separate from C'; I, is apparently missing; and lower molars are nyctalodont. Chromosomal complement has 2n = 36 and FN = 50. Habitat. Primarily mature deciduous mixed forests at elevations of 100-1500 m (favoring elevations above 1000 m). Endo’s Pipistrelles avoid urban areas, unlike related Japanese Pipistrelles (P. abramus). There is one record of Endo’s Pipistrelle in secondary forest in suburban Tokyo. Food and Feeding. Endo’s Pipistrelle is insectivorous. Breeding. Endo’s Pipistrelle seems to be seasonally monoestrous, with delayed fertilization. A pregnant female was captured in mid-August in Hiroshima prefecture and lactating females in late July in Ishikawa ...
