Shamel’s Horseshoe <b>Bat</b> <i>Rhinolophus shameli</i> French: Rhinolophe de Shamel / <b>German:</b> Shamel-Hufeisennase / <b>Spanish:</b> Herradura de <i>Shamel</i> <b>Taxonomy.</b> <i>Rhinolophus coelophyllus shameli</i> Tate, 1943, “ Koh Chang (Island), <i>Gulf</i> of Siam, Siam [= Thailand].” <i>Rhinolophus shameli</i> is included in the <i> <i>euryotis</i> species group, and appears to be sister to the rest <i>of</i> the <i>euryotis</i> group or as close to <i>R. stheno,</i> although this is based on limited genetic data. <i>R. shameli</i> appears to be closely related to <i>R. coelophyllus,</i> based on morphology; the two are often confused, and some records of each were previously attributed to the wrong species. Monotypic.</i> <b>Distribution.</b> E &amp; SE Thailand (including Koh Chang), C &amp; S Laos, S Vietnam (including Phu Quoc I), and Cambodia. Descriptive <b>notes.</b> Head-body 47-48- 1 mm, tail 17-23 mm, ear 16-1-21- 4 mm, hindfoot 7-5-10- 2 mm, forearm 43- 4-48 mm; weight 7-5-12- 5 g. Dorsal pelage varies from <i>gray</i> or bufiy brown to darker brown or reddish orange brown (base of hairs paler); ventral pelage varies from pale bufiy brown to <i>nearly</i> creamy white in some individuals, or is slighdy paler orange in reddish individuals. Noseleaf has very short and 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 <i>continuously</i> convergent sides and rounded tip; horseshoe is moderately wide (9-11 - 4 mm) but wider on average than in the Croslet Horseshoe Bat <i>(. coelophyllus),</i> and has <i>weakly</i> developed lateral leaflets. Lower lip has three mental grooves. Skull is moderately robust (<i>zygomatic</i> width is greater than mastoid width, sometimes barely); sagittal crest is <i>moderately</i> developed; anterior median and lateral swellings are very well developed; posterior swellings are less developed; entire rostral <i>swelling</i> is larger than that <i>of</i> the Croslet Horseshoe <b>Bat</b>; frontal depression is shallow; supraorbital crests are low and not sharp. P2 is moderate in size and within tooth row, separating C1 from P4; P3 is small (<i>occasionally</i> absent) and is extruded from tooth row, and P2 and P4 are usually touching. Dental formula is the usual <i>of</i> 32 teeth for the genus, or <i>only</i> 30 teeth when a lower premolar is missing. Habitat. <i>A</i> variety of forest habitats, such as mixed deciduous forests, deciduous and dwarf dipterocarp forests, <i>dry</i> evergreen forests, and <i>lowland</i> evergreen forests. Shamel’s Horseshoe Bat is known from both disturbed and undisturbed habitats and is often <i>associated</i> with lowland regions. <b>Food and</b> Feeding. No information. Breeding. Pregnant females have been captured between December and April in Chachoengsao <i>Province</i>, Thailand, and in February in Cambodia. Two lactating females were collected in July in Vietnam. <b>Activity patterns.</b> Shamel’s Horseshoe Bat roosts in caves and caverns. Calls are a FM/ CF/FM shape with peak F recorded at 67-5-70-8 kHz across Thailand and Cambodia, and 65-68-2 kHz in Vietnam. <b>Movements, Home range and Social</b> organization. No information. Status <b>and Conservation.</b> Classified as Least Concern on <i>The IUCN Red List.</i> Shamel’s Horseshoe Bat is <i>relatively</i> widespread and common throughout its distribution and does not seem to face any major threats at present. <b>Bibliography.</b> Abramov <i>et</i> al.
