Ziama horseshoe bat
The Ziama horseshoe bat (Rhinolophus ziama) is a species of bat in the family Rhinolophidae. It was first described in 2002. It is found in Guinea, Sierra Leone, and Liberia. Its natural habitats are subtropical and tropical moist lowland and monstane forests. In 2013, Bat Conservation International listed this species as one of the 35 species of its worldwide priority list of conservation. Description
The Ziama horseshoe bat can be distinguished from the Maclaud's horseshoe bat because it is significantly smaller in body size. While it is smaller than Maclaud's horseshoe bat, it is still one of the largest horseshoe bats in Africa. They weigh between  as adults. Their forearms are . Their ears are  long, pointed at the tips, and have 11-12 inner folds. Their noseleafs are  wide, almost covering their snouts. Their pelage is soft and woolly in texture, with dorsal hairs paler at the base and darker at the tip; ventral hairs are uniformly buffy

R. maclaudi group
As the genus Rhinolophus is quite speciose, it is split into groups. Maclaud's horseshoe bat is the identifier of one of these groups, called the maclaudi group, which currently consists of six species, three of which were not described before 2003. Members of this group have large ears, and a diminished connection between the sella and lancet. Maclaud's horseshoe bat—R. maclaudi
Rhinolophus willardi—discovered in 2013
Ruwenzori horseshoe bat— R. ruwenzorii
Hill's horseshoe bat—R. hilli
Rhinolophus kahuzi—discovered in 2013
Ziama horseshoe bat—R. ziama
R. maclaudi and R. ziama are considered the two West African taxa, while the other four species are found further east around the Albertine Rift. The West African species are larger in size than the East African species, with R. maclaudi as the largest bat of the species group. As these species are very similar morphologically, it was previously thought that R. hilli and R. ruwenzorii were the same taxon, and that the taxon was a subspecies of the Maclaud's horseshoe bat. Conservation
As of 2002, only four specimens had ever been encountered; all were captured via mist-netting in 1990 and 1992. Three were encountered in the Ziama Massif of Guinea, while the other was captured in Wonegizi Nature Conservation Unit in Liberia. Based on the two known locations of occurrence at the time, the species range was feared to be as small as  There are concerns that its habitat in Liberia could have been damaged by the Second Liberian Civil War. In 2006, a fifth specimen was captured in Sierra Leone, extending the range of occurrence by . It is one of five species of microbat in Africa listed as endangered by the IUCN. References
