description: 88. <i>Croslet</i> Horseshoe <b>Bat</b> <i>Rhinolophus coelophyllus</i> French: Rhinolophe de <i>Peters</i> / <b>German:</b> Thai-Hufeisennase / <b>Spanish:</b> Herradura thai <b>Taxonomy.</b> <i>Rhinolophus coelophyllus</i> Peters, 1867, “ Moulmein [= Mawlamyine], Burmah [= Burma = Myanmar]... Salween valley. ” <i>Rhinolophus coelophyllus</i> is included in the <i>euryotis</i> species group. It is considered to be <i>closely</i> related to <i>R. shameli,</i> based on morphology; the two are often confused, and some records of each were previously attributed to the wrong species. <i>Monotypic</i>. <b>Distribution</b>. NC, <i>C</i> &amp; SE Myanmar, Thailand (including Tarutao I), C Laos, and NW Peninsular Malaysia (including Langkawi I). <b>Descriptive notes</b>. <i>Head-body</i> 36-50 mm, tail 16-4-23- 9 mm, ear 15- 1-20 mm, hindfoot 7-8-9- 6 mm, forearm 41-6-47- 8 mm; weight 6-2-8- 6 <i>g</i>. There is considerable <i>geographic</i> variation in terms of skull measurements. Dorsal pelage varies from grayish brown to dark brown, with some individuals reddish brown (base of hairs paler); ventral pelage is pale <i>buff</i> brown and can be <i>nearly creamy</i> white in some individuals, or pale orange in reddish individuals. Ears are medium-sized. Noseleaf has very short, thick lancet with convex outline; connecting process is arched and proximally inserted into densely haired vertical fissure in lancet; sella is short, with almost parallel or continuously convergent sides and rounded tip; horseshoe is moderately wide (8-2-10- 4 mm) and has <i>weakly</i> developed lateral leaflets. Lower lip has three mental grooves. Skull is moderately built (zygomatic width is slightly greater than mastoid width); sagittal crest is moderately developed; anterior median swellings are inflated and distinctly elevated above posterior swellings; anterior border of rostrum is shorter than in Shamel’s Horsehsoe Bat <i>(. shameli);</i> nasal swelling as whole is smaller than in Shamel’s Horsehsoe <b>Bat</b>; frontal depression is deep and pronounced with well-defined supraorbital ridges, although specimens from central and north Myanmar have less developed depressions and supraorbital ridges; canines are slender. P2 is moderately large and within the tooth row; P3 is small and extruded from tooth row; P and P4 are touching. Chromosomal complement has 2n = 62, FN = 64, and FNa = 60 (Thailand). <b>Habitat.</b> The <i>Croslet</i> Horseshoe Bat seems to favor limestone karst regions with mixed deciduous forest <i>but</i> can also be found in a variety of other habitats, including deciduous dipterocarp forests, moist evergreen forests, hill evergreen forests, dry evergreen forests, pine forests, rubber plantations, orchards, and extensive agricultural land. Throughout the species’ distribution, it can be found from near sea level up to 1500 m elevation. <b>Food and</b> Feeding. No information. Breeding. Pregnant females were captured in March, and an immature male was captured in October on Tarutao Island. <b>Activity patterns.</b> Croslet Horseshoe Bats roost in caves and tunnels by day. Calls are a FM/CF/FM shape with a peak F recorded at 76-1-84-8 kHz across Thailand, 75- 80 kHz in Kanchanaburi Province, Thailand, 74-5—74-9 kHz in Myanmar, and 76 kHz in Laos. <b>Movements, Home range and Social organization.</b> Croslet Horseshoe Bats roost in <i>relatively</i> large colonies, often with c.100-150 individuals. Up to 900 bats have been recorded roosting in a single cave. <b>Status and Conservation.</b> Classified as Least Concern on <i>The IUCN ed List.</i> The Croslet Horseshoe Bat is <i>relatively</i> widespread and common throughout its distribution and does not seem to face <i>any</i> major threats at present. <b>Bibliography.</b> Bates, Bumrungsri &amp; Csorba (2008 <i>c</i>), Bates, Thi <i>Mar-Mar et</i> al.
