description: 43. Osgood’s Horseshoe <b>Bat</b> <i>Rhinolophus osgoodi</i> French: <i>Rhinolophe d'Osgood</i> / <b>German:</b> <i>Osgood-Hufeisennase</i> <b>/ Spanish:</b> Herradura de Osgood Taxonomy. <i>Rhinolophus osgoodi</i> Sanborn, 1939, “ Nguluko (25° 5’ N. Lat., 100° 15’ E. Long.), north of Likiang, Yunnan, China. ” <i>Rhinolophus osgoodi</i> was formerly in the <i>pusillus</i> group <i>but</i> is in the <i>macrotis</i> group here based on molecular studies and morphological similarities. <i>Rhinolophus</i> <i>osgoodi</i> is sometimes considered a subspecies of <i>R lepidus,</i> but <i>they</i> are morphologically distinct. Recent genetic studies have shown that a clade composed of a paraphyletic assemblage of <i>A siamensis</i> and <i>R macrotis</i> actually represents three distinct species, <i>R osgoodi</i> (specimens <i>originally</i> identified as <i>“ Rhinolophus</i> spi <i>”), R episcopus,</i> and <i>R siamensis.</i> Until then, <i>R osgoodi</i> was <i>only</i> known from specimens from the type locality. Monotypic. <b>Distribution.</b> S China (Sichuan, Yunnan, Guizhou, and Hunan) and N Vietnam. Descriptive <b>notes.</b> Tail 15-22 mm, ear 10-14 mm, hindfoot 7-9- 5 mm, forearm 40- 45 mm; weight 5-6 g. Dorsal pelage is pale brown (hairs have gray bases); venter is paler and grayer. Ears are medium to large in size. There is no known orange morph. Males lack axillary tufts. Noseleaf has <i>relatively</i> short, almost straight-sided lancet with pointed tip; connecting process is high, <i>but</i> more or less pointed; sella is <i>relatively</i> broad, with parallel sides and widely rounded tip; and horseshoe is wide (<i>c</i>.6- 4 mm), covers entire muzzle, has very shallow median emargination, and lacks lateral leaflets. Skull is moderately robust; zygomatic width is smaller than mastoid width; anterior median swellings and posterior compartments are moderately developed; rostral profile is sloped backward; sagittal crest is <i>weakly</i> developed; and frontal depression is shallow and bordered by sharp, well-defined supraorbital ridges. P2 is of medium size and in tooth row, separating C1 and P4; P3 is small and completely or <i>partially</i> displaced labially; and <i>P</i> 2 and P4 are very close to one another but do <i>not</i> touch. <b>Habitat.</b> Caves surrounded by <i>secondary</i> growth or agricultural fields. <b>Food and</b> Feeding. No information. <b>Breeding.</b> No information. Activity <b>patterns.</b> Osgood’s Horseshoe Bats are nocturnal. <b>Call</b> shape is <b>FM</b> /CF/FM, with F component at 85—94 kHz. <b>Movements, Home range and Social organization.</b> No information. <b>Status and Conservation.</b> Classified as Data Deficient on 77 <i>ie</i> IUCN <i>Red List.</i> Osgood’s Horseshoe Bat was previous known <i>only</i> from Yunnan, but recent genetic <i>analysis</i> has shown that the species is much more widespread than previously thought. However, additional research is needed regarding ecology, distribution, and threats of this species. <b>Bibliography.</b> Csorba et <i>al.</i> (2003), <i>LiuTong</i> et al.
