Andersen's Roundleaf Bat

Andersen's roundleaf bat is a small Asian Hipposideros described in 1918. For much of the twentieth century its named forms were folded into the bicolored roundleaf bat, but current taxonomy again recognizes H. gentilis as a distinct species. Noseleaf, skull, acoustic and genetic evidence are important in this complex (Mammal Diversity Database; specialist taxonomic studies).

It ranges from South Asia through southern China and mainland Southeast Asia. Records are associated with caves and forest, where it roosts by day and catches small nocturnal insects after dusk. Because older literature often used H. bicolor in a broad sense, ecological claims from those accounts cannot safely be assigned to this species without specimen evidence (Mammal Diversity Database). It is Nationally Least Concern (Thailand Red Data 2025).
