It was described as a new species in 1968. The holotype used to describe the species was collected by J. P. Adam, who is likely the eponym for the species name "adami."[2] The genus Rhinolophus, of which the Adam's horseshoe bat is a member, is divided into species groups, as it is quite speciose. The Adam's horseshoe bat is the identifier of one of these groups, the adami group. The only other member of the adami group is the Maendeleo horseshoe bat.[3]
Description
Its forearm length is 47–49 mm (1.9–1.9 in). Its ears are relatively long, at 25–26 mm (0.98–1.02 in). It has a large nose-leaf, at 15–16 mm (0.59–0.63 in) long and 8.5–9 mm (0.33–0.35 in) wide.[2]
It is currently evaluated as data deficient by the IUCN. As of 2019, the species had not been observed since the series of ten individuals used to describe the species in 1968.[1]
