Etymology: "Specific epithet ysbryda, from Welsh “ysbryd,” a ghost or spirit, latinized by the addition of a feminine ending 'a' and to be treated as a noun in apposition. The name alludes to the species’ ghostly appearance, nocturnal, predatory behaviour and the element of mystery surrounding its origin."
