description: 107. Chiew Kwee’s Horseshoe <b>Bat</b> <i>Rhinolophus chiewkweeae</i> French: Rhinolophe de Chiew Kwee / <b>German:</b> Chiew-Kwee-Hufeisennase <i>I</i> <b>Spanish:</b> Herradura <i>de</i> Chiew <i>Kwee</i> Taxonomy. <i>Rhinolophus chiewkweeae</i> Yoshiyuki &amp; B. L. Lim, 2005, “Gunung Ledang, 2°84’N, 102°57’E, Tangkak, Muar,Johore, a submontane dipterocarp forest approximately 1276 m in elevations, Malaysia.” <i>Rhinolophus chiewkweeae</i> is included in the <i>pearsonii</i> species group, and appears to be <i>closely</i> related to <i>R.pearsonii.</i> Monotypic. Distribution. <b>Malay</b> Peninsula, including Langkawi I. Descriptive notes. Head—body 51-5—65 mm, tail 14- 7-19 mm, ear 20- 1-26 mm, hindfoot 12-14- 4 mm, forearm 51-9- 56- 1 mm. Dorsal pelage is orangish brown, while ventral pelage is lighter. Ears are moderately large. Noseleaf has a broadly triangular, long, and nearly parallel straightsided lancet; connecting process starts at the tip of the sella and is low and arched; sella is broadly rounded at the tip and broader at the base; horseshoe is wide (11- 6 mm) and covers the muzzle, with a distinct median emargination. Lower lip has one mental groove. Baculum is similar to that of Pearson’s Horseshoe Bat (. <i>pearsonii)</i> and is fairly long (3- 3 mm long), having a deep U-shaped emargination and a thick lateral expansion on the ampulla. Skull is large and robust (zygomatic width greater than mastoid width); anterior median swellings are well developed; lateral swellings are less swollen and the posterior swellings are <i>relatively</i> concave; rostral profile is low; frontal depression appears to be <i>relatively</i> shallow; sagittal and supraorbital crests are well developed. C1 is weak; P2 is relatively large and within the tooth row; P3 is minute and extruded from the tooth row, allowing P2 and P4 to touch. Habitat. Typically found in hill and lowland dipterocarp forests, at elevations from around sea level up to 1276 m. <b>Food and</b> Feeding. No information. Breeding. No information. <b>Activity patterns.</b> Call shape is <b>FM</b> /CF/FM with peak F of 53-6-54-7 kHz, duration of 28-4-63-3 milliseconds, and interpulse interval of 32—289 milliseconds, in eastern Peninsular Malaysia. <b>Movements, Home range and Social organization.</b> No information. <b>Status and Conservation.</b> Not assessed on <i>The</i> IUCN <i>Red List.</i> The overall range of Chiew Kwee’s Horseshoe Bat is quite small. Deforestation is <i>likely</i> to be a major threat to the species. Due to reservoirs for hydroelectric schemes, mercury accumulates at high concentrations in this species, which may well be a localized threat. <b>Bibliography.</b> <i>Kumaran</i>, Daud et al.
