Abstract: Diclidurus scutatus Peters, 1869, is known from Venezuela, Guyana, Surinam, French Guiana, Brazil, Ecuador, and Peru. In Peru D. scutatus D. scutatus from a known locality for Peru. We also provide an updated distribution map for the species. was previously known from a single specimen without a specific locality. Here we report the first record of
The genus Diclidurus provide an updated distribution map for the species. This Diclidurus for albus, ingens, and scutatus Wied-Neuwied, and Depanycteris 1820 for isabellus includes four species grouped into two subgenera: specimen, an adult female, MUSM 37068 (Figure 2), was distributed from western Mexico, southeastward to eastern collected at the mouth the Yavarí river on Lago Preto, Lago (Hood and Gardner 2008; Simmons 2005).

Members of this genus are some Cecropia sp., Helicona sp., and Piper sp. The height of the forest canopy was 18 m and characterized by the nearlyto pale obliteratedbrownish pelage; by markedly a small first broadened upper premolar supraorbital not presence of Bactris spp., Cecropia sp., and Inga sp.
