Restricted by O. Thomas and R.. Wroughton in 1909 to “Kalipoetjang, Tji-Tandoei River, S.Java.” <i>Rhinolophus canuti</i> is included in the <i> <i>euryotis</i> species group and is probably related to. <i>creaghi</i> and <i>R arcuatus,</i> although it has not <i>yet</i> been included in <i>any</i> phylogenetic studies. Two subspecies recognized.</i> <b>Subspecies and Distribution.</b> . <i>c. canuti</i> Thomas &amp; Wroughton, 1909 — Java (three localities), and Nusa Barong ail'd Bali Is. . <i>c.</i> timorensis R. E. Goodwin, 1979 — Timor I. Descriptive <b>notes.</b> <i>Head-body</i> 51-62 mm, tail 19-24 mm, ear 21-24- 1 mm, forearm 47-6-51- 2 mm. Fur is long and fine. Dorsal pelage is variable, ranging from dark red to wood brown (hairs paler at base), and ventral pelage varies between wood brown and light drab. Ears are large. Noseleafhas concave sided lancet; connecting <i>process</i> is very low (slightly more developed in timorensis', and curved, and <i>has</i> fringe of <i>hairs along</i> the edge; sella gradually narrows to rounded tip and there is a tuft ofhair between sella and lancet (hairs much less dense than in Creagh’s Horseshoe Bat, <i>R creaghi),</i> which varies in color from reddish brown (<i>timorensis)</i> to straw yellow (canuti); horseshoe is wide (<i>c</i>.ll mm). Skull is heavily built (<i>zygomatic</i> breadth <i>slightly</i> exceeding mastoid breadth); anterior median swellings are well inflated and extend posteriorly; lateral swellings are prominent; posterior swellings are <i>relatively</i> reduced; rostral profile is sharply concave; sagittal crest is well developed; frontal depression is well to <i>moderately</i> developed; supraorbital crests have sharp ridges. <i>C</i> 1 is moderately strong and long; P2 is <i>relatively</i> large and within the tooth row, or crowded slighdy out of line; P3 is small and completely extruded, or rarely missing; P9 and P4 are in contact Dental formula is the usual of 32 teeth for the genus, or <i>only</i> 30 teeth when a lower premolar is missing. Habitat. Found almost exclusively in intact forest, although it may <i>occasionally</i> forage over cultivated land. Recorded at 550 m on Timor. <b>Food and</b> Feeding. No information. Breeding. No information. <b>Activity patterns.</b> Knud’s Horseshoe Bat roosts in caves <i>by</i> day. <b>Movements, Home range and Social organization.</b> Knud’s Horseshoe Bat appears to roost in large colonies. <b>Status and Conservation.</b> Classified as Vulnerable on <i>The IUCNed List.</i> Knud’s Horseshoe Bat is <i>currendy</i> only known from a few scattered localities. It prefers undisturbed forests, which <i>severely</i> limits its distribution. The species was thought perhaps to be extinct inJava, but recent sampling efforts have shown that it is still present. This species is threatened by deforestation and roost disturbance throughout its distribution. <b>Bibliography.</b> Csorba eta/.
