Greater Japanese Horseshoe Bat

The greater Japanese horseshoe bat, Rhinolophus nippon, is a member of the greater horseshoe bat complex formerly treated broadly as R. ferrumequinum. Recent molecular work recognizes R. nippon across eastern and southern China, Korea and Japan. Horseshoe bats are named for the elaborate noseleaf surrounding the nostrils, a structure associated with their nasal echolocation. Older Korean references may consequently list the same lineage as Rhinolophus ferrumequinum or under named subspecies (Ikeda and Motokawa 2021; Uvizl et al. 2024).

Mitochondrial studies resolve Northeast Asian R. nippon into several geographic lineages. Samples from South Korea group with continental and western Japanese material, and the Japanese populations are not a single exclusive lineage. The pattern has been interpreted as evidence of complex movement across former land connections, including movement involving the Korean Peninsula. Exact Korean roost, diet, body-size and breeding claims are omitted here because the opened phylogeographic studies address evolutionary history rather than a full ecological account (Ikeda and Motokawa 2021; Koh et al. 2016).
