The intermediate horseshoe bat is a medium to fairly large horseshoe bat with brown to ochraceous-buff upperparts and brown to cream-buff underparts. Juveniles are lighter than adults. Its noseleaf has a slightly concave, fiddle-shaped sella and a straight-sided, pointed lancet. The species resembles the Chinese rufous horseshoe bat, but generally has a larger forearm and differs in noseleaf form and finger proportions. (Bats in China)
Intermediate horseshoe bats usually roost in caves, sometimes sharing those shelters with other bat species. Individuals have also been found inside a hollow tree trunk in tropical forest in southern Yunnan. Documented elevations range from approximately 670 to 1,692 m. The species produces long constant-frequency echolocation calls with brief frequency-modulated components at the beginning and end; recorded Chinese peak frequencies vary geographically and overlap those of the similar Chinese rufous horseshoe bat.
