Descriptive notes. Head—body 38-42 mm, tail 26-26-7 mm, ear 11-127 mm, hindfoot 3:9—4-4 mm, forearm 33-34-2 mm. No specific data are available for body weight. Greatest length of skull 12:9-13-8 mm, condylo-incisive length 12:5-13-6 mm, rostral length 4-9-5 mm, zygomatic breadth 6-8-7-2 mm, and maxillary tooth row length 5-3-5-6 mm. Dorsal pelage of Patricia’s Disk-winged Bat is unicolored light brown for most of its length and slightly grayish. Basal part of dorsal fur is lighter than the rest. This is in contrast to tricolored ventral fur (7 mm in length), with basal one-third whitish, middle light brown, and tip darker. Pelage between shoulders is woolly and c¢. 11 mm long. Proximal part of forearm is densely furred with long hairs. Most of pinnae are covered in fur except for naked distal part. Wing membranes are dark brown. Plagiopatagium and uropatagium have transverse lines of elastine fibers, dotted with evenly spaced somatosensory domes. Dorsum of uropatagium is covered with long hairs proximally and sparsely distally. Tips of wings are sparsely furred with long hair. Proximal one-half of uropatagium is densely covered with long hair, and wingtips are sparsely covered with long hair. Calcar is long (8:5-12 mm) and has two lappets and five small skin projections between foot disk and proximal lappet. Disks of foot and thumb are oblong. Thumb disks are 2: 74 mm long and 1-8-3-1 mm wide. Foot disks are 1-6-2-5 mm long and 1-4-2-2 mm wide. Rostrum is more slender and shorter than globular braincase. Lower incisor (I,) is only slightly smaller than I, and I,, and I, has two well-developed accessory cusps. Upper incisors are bicuspid, I? and I’ contact each other, and diastema separates them from the canine. Skull of Patricia’s Disk-winged Bat differs from all other species of Thyroptera by having a rostrum that is shorter than the braincase. Rostra of the other Thyroptera are equal or longer in length to braincases.

Habitat. Primary and secondary lowland rainforest up to elevations of 300 m. Patricia’s Disk-winged Bats were collected near the Ucayali River 2-5 km from the banks on a ter race above the river floodplain, with well-drained soils and distinctive riparian formation.

Food and Feeding. No information.

Breeding. No information.

Activity patterns. Holotype of Patricia’s Disk-winged Bat was roosting with another individual in a dead Cecropia (Urticaceae) leaf ¢. 2 m aboveground in a secondary forest. Two additional individuals at the same location used a ground level roost.

Movements, Home range and Social organization. No information.

Status and Conservation. Classified as Data Deficient on The IUCN Red List. Insufficiently known as very few specimens are available. No protected areas are included within the known distribution of this species.
