Descriptive notes. Forearm 100-8 mm. No other specific measurements are available. The Crested Leaf-nosed Bat is has similar morphological characters to the Fierce Leaf-nosed Bat (Ä dmops). Ears are large, triangular, and slightly concave below tips. Anterior noseleaf is well developed and has four supplementary lateral leaflets. Fourth is tiny and third is small. Intermediate noseleaf is swollen and has weak medium crest. Upper margin ofposterior leaf is semicircular. There is a central septum with two lateral and less pronounced septa, which form four cells on frontal surface. Pelage coloration has not been well described as all the known specimens have been preserved in alcohol for many years; it is probably similar to that ofthe Fierce Leaf-nosed Bat, whitish-brownish on dorsum and yellowishbrownish on ventral area.

Status and Conservation. Classified as Data Deficient on T/ze IUCN Red List, due to the lack of information available. No recent captures or registers of the Crested Leafnosed Bat are known. Population trends are also unknown, as are population size, distribution, ecology, and threats. More research on this species is required in order to define adequate management and conservation measures.
