Homfray’s Horseshoe <b>Bat</b> <i>Rhinolophus andamanensis</i> French: Rhinolophe <i>de</i> Homfray <i>I</i> German: Andamanen-Hufeisennase / <b>Spanish:</b> Herradura <i>de</i> Homfray <b>Other common names:</b> <i>Andaman</i> Intermediate Horseshoe Bat Taxonomy. <i> Rhinolophus affinis <i>andamanensis</i> Dobson, 1872, “ Andaman Islands,” India.</i> <i>Rhinolophus andamanensis</i> is included in the <i>euryotis</i> species group and is sister to <i>R affinis.</i> It was <i>only recently</i> recognized as a species distinct from <i>R affinis</i> by. Srinivasulu and coworkers in 2019, based on genetic, morphometric, and acoustic data. Monotypic. <b>Distribution.</b> Andaman Is (North Andaman, Interview, Middle Andaman, Baratang, South Andaman, and Little Andaman). Descriptive <b>notes.</b> Head-body 58- 2 mm (average), tail 17- 9—31 mm, ear 18-1-23- 9 mm, hindfoot 9-7—14- 7 mm, forearm 46-7—56- 6 mm. Dorsal pelage is brown to bright orange, with ventral pelage very similar. Ears are small. Noseleaf has parallel-sided lancet with pointed tip; connecting process is rounded and sparsely haired; sella is slightly concave and pandurate in shape; horseshoe is <i>relatively</i> broad and covers muzzle, with well-defined median emargination, and distinct lateral leaflets. Lower lip has three mental grooves. Baculum is 2—3 mm long, has deeply notched ventral margin of basal cone but is less notched on dorsal margin; it has smaller notches on lateral sides; shaft is roughly circular in cross section and bends downward toward tip. Skull is robust; sagittal <i>crest</i> is well developed; interorbital region is broad; anterior median swellings are comparatively less inflated; posterior swellings are well defined; zygomatic arches are robust; canines are robust. P2 is small and within tooth row; P3 is small and extruded from tooth row, allowing P2 and P4 to touch. Habitat. Forested habitats across the islands. <b>Food and</b> Feeding. No information. <b>Breeding.</b> No information. <b>Activity patterns.</b> Homfray’s Horseshoe Bat roosts in limestone caves, forest caves, and sometimes holes and tree hollows. Calls have a FM/CF/FM shape with a peak F recorded at 56-4-58-5 kHz (mean 57-6 kHz). <b>Movements, Home range and Social organization.</b> Homfray’s Horseshoe Bat roosts in large colonies and has been observed roosting with Andaman Horseshoe Bats (. <i>cognatus),</i> Diadem Leaf-nosed Bats (Hipposideros <i>diadema),</i> Andersen’s Leaf-nosed Bats (<i>H. gentilis),</i> Grand Leaf-nosed Bats (<i>H. grandis),</i> and Horsfield’s Myotis (<i>Myotis horsfieldii).</i> <b>Status and Conservation.</b> Not assessed as a separate species on <i>The</i> IUCN <i>ed List,</i> where it is included under the Intermediate Horseshoe Bat (<i>R. affinis)</i> as Least Concern. Homfray’s Horseshoe Bat has a restricted range, but appears to be <i>relatively</i> common throughout the Andaman Islands. Further studies into the species’ ecology and potential threats are needed. <b>Bibliography.</b> Srinivasulu, Srinivasulu, Srinivasulu, <i>Gopi</i> et al.
