The Ziama Horseshoe Bat is one of the largest horseshoe bats in Africa. Dorsal pelage is <i>buffy</i> brown (hairs are pale buff basally and pale brown at tips); venter is paler dirty buff, with pale brown sheen. There is no known orange morph. Males lack axillary tufts. Ears are <i>very</i> long (39-63% of forearm length), with 11—12 internal folds and very large antitragus. Noseleaf has long and narrow subtriangular lancet, with <i>nearly</i> parallel sides distally and rounded tip; connecting process is largely reduced, low, and concave, leaving large depression between sella and lancet; sella is inclined forward, with <i>nearly</i> parallel sides and enlarged lobes at base, forming heart-shaped, corolla-like cup; nostrils are bordered laterally by raised and <i>nearly</i> straight rims that almost reach anterior margin of horseshoe; and horseshoe is of medium width at 11- 5 mm, <i>almost</i> covers muzzle, and has no lateral leaflets and inconspicuous or absent median emarginadon. Lower lip has one medial groove. <i>Wings</i> and uropatagium are dark gray. Skull is large and slender, with weak zygomatic arches that are <i>dorsally</i> notched (zygomatic width is subequal to mastoid width); nasal swellings are high domed, with <i>roughly</i> heart-shaped chambers in dorsal view; frontal depression is very deep; sagittal crest is moderately developed <i>anteriorly</i> and poorly developed posteriorly; infraorbital bridge is very elongated and slender; and interpterygoid groove is very deep. P2 is small and in tooth row, separating C1 and P4; P3 is small and slightly to completely displaced labially; and P2 and P4 are in contact or separate. Habitat. <i>Primary</i> and <i>secondary</i> montane and lowland tropical moist forests, recorded at elevations of c. 600 m. <b>Food and</b> Feeding. No information. Breeding. No information. Activity <b>patterns.</b> Day roosts of Ziama Horseshoe Bats are likely caves, although no records from roosts are known. <b>Movements, Home range and Social organization.</b> No information. <b>Status and Conservation.</b> Classified as Endangered on <i>The IUCN ed List.</i> The Ziama Horseshoe Bat is known from only a few specimens in a restricted distribution. It might be threatened by habitat destruction from logging, mining, and agricultural expansion. <b>Bibliography.</b> ACR (2018), Fahr (2008c, 2013i), ahr <i>et</i> al.
