description: 77. <b>McIntyre’s</b> Horseshoe <b>Bat</b> <i>Rhinolophus mcintyrei</i> French: Rhinolophe de McIntyre/ <b>German:</b> Mclntyre-Hufeisennase / <b>Spanish:</b> Herradura de McIntyre <b>Taxonomy.</b> <i>Rhinolophus arcuatus mcintyrei</i> Hill &amp; Schütter, 1982, “ 4 km ENE Telefomin, W[est] Sepik <i>Province</i>, Papuan New Guinea (05°06’S, 141°41’ <i>E</i>).” <i>Rhinolophus mcintyrei</i> is placed within the <i>euryotis</i> group and appears to be sister to a clade that includes <i>R. euryotis, R. tatar,</i> <i>R. arcuatus,</i> and <i>R. inops</i> or. <i>subrufus,</i> based on mitochondrial data. It was originally described as a subspecies of <i> R. <i>arcuatus</i> and has typically been treated thus, but following a <i>recent</i> genetic study by L. E. Patrick and colleagues in 2013, the taxon has been elevated to species status. Monotypic.</i> Distribution. WC <b>&amp;</b> C Papua New Guinea. Descriptive <b>notes.</b> Head-body 48-64 mm, tail 16-23 mm, ear 15-22 mm, hindfoot 8-13 mm, forearm 47- 5-54 mm; weight 9-15 g. <i>McIntyre’s</i> Horseshoe Bat is generally similar to the Bornean <i>Woolly</i> Horseshoe Bat (<i>R.proconsulis),</i> the Poso Horseshoe Bat (. <i>belligeratar),</i> and the Arcuate Horseshoe Bat (. <i>arcuatus)</i> but is separated by its more expanded intemarial region, shorter and wider sella, and more inflated anterior median rostral swellings. Dorsal pelage is slightly reddish brown or dark brown (hairs whitish at base), whereas ventral pelage is paler. Ears are <i>moderately</i> long. Noseleaf has straightsided lancet with a pointed tip; connecting process is arcuate, forming a semicircle; sella is broadly ovate and wide basally, being <i>slightly</i> narrower than intemarial cup for much of its length before tapering slightly toward rounded tip; horseshoe is <i>relatively</i> wide (8-7-9- 7 mm), <i>nearly</i> covers the muzzle, and has slight median emargination. Lower lip has three mental grooves. Skull is <i>relatively</i> slender; braincase is elongate and <i>slightly</i> inflated; interorbital region is abruptly narrowed; anterior median swellings are well developed and circular in outline; posterior swellings are less pronounced but still defined; rostral profile is distinctly concave in lateral view; sagittal crest is moderately developed; frontal depression is very shallow; supraorbital crests are <i>slightly</i> developed; canines are relatively slender and <i>slightly</i> curved (smaller and less <i>massive</i> than in the Bornean <i>Woolly</i> Horseshoe Bat). P2 is small and in the tooth row; <i>P</i> 3 is <i>very</i> small and completely extruded from the tooth row. Habitat. Typically found in lowland and hill forest habitats, such as <i>primary</i> lowland alluvial and hill forests that exhibit complex <i>four-layered</i> canopies. Recorded at elevations of 270-1600m. <b>Food and</b> Feeding. McIntyre’s Horseshoe Bat probably forages using a mixture of aerial-hawking and gleaning; it is a slow, maneuverable flier. Breeding. No information. <b>Activity patterns.</b> <i>McIntyre’s</i> Horseshoe Bat is nocturnal and spends the day roosting in limestone caves and abandoned mines. Call shape is FM/CF/FM with a peak F recorded at 70—72 kHz. <b>Movements, Home range and</b> Social organization. McIntyre’s Horseshoe Bats are known to roost in small groups of at least a dozen. Status <b>and Conservation.</b> Classified as Data Deficient on <i>The</i> IUCN <i>Red List.</i> Although there is <i>only</i> limited information available on this species’ <i>ecology</i> and threats, McIntyre’s Horseshoe Bat is likely to be threatened by deforestation and other forms of human disturbance, which are common in the lowland forests it inhabits. <b>Bibliography.</b> Bonaccorso (1998), Hill &amp; Schütter (1982), <i>Leary</i> &amp; Pennay (2011), Patrick &amp; Ruedas (2017b), Patrick et al.
