Descriptive notes. Head-body 49-57 mm, tail 8-12 mm, ear 13-14 mm, hindfoot 10-11 mm, forearm 35-36 mm; weight 9.3-10-2 g. Dashe’s Nectar Bat is the larger species of Hsunycteris . Dorsal hairs are 9-10 mm, distinctly bicolored with pale pinkish bases (20% of length) and pale brown tips; ventral hairs are c¢. 7 mm, similar in color to dorsal pelage, bicolored with pale pinkish bases (30% of length) and pale brown tips. Muzzle is elongated, with lower jaw extending slightly beyond upperjaw. Chin has several small dermal papillae arranged in a V-shape and separated by wide cleft. Weakly developed centralrib of noseleaf extendsto tip. Ears and wing membranes are blackish brown, and wings attach to ankles. Forearms are naked. Dorsal surface of uropatagium is naked. Rostrum is broad, and postorbital region is not inflated and lacks lateral projections. Lateral margin of infraorbital foramen does not project beyond rostral outline in dorsal view. I! are larger than I. In palatal view, gaps are obvious between I' and I?, and P* have weakly developed lingual cusps. Molars are broad. Extra upper premolaris present in holotype but not paratype and thought to represent supernumerary teeth.

Habitat. Only recorded in Amazonian lowlands of north-eastern Peru at elevations below 200 m. Except for the narrow floodplain of the Rio Galvez, landscape surrounding this area consists of low hills and terraces. All Dashe’s Nectar Bats were taken in tall, undisturbed forest on hilly interfluvial terrain far from palm swamps and seasonally flooded formations of the Galvez floodplain.

Food and Feeding. No information.

Breeding. No information.

Activity patterns. All three specimens were taken from two diurnal roosts beneath undercut bank of small streams in primary forest.

Movements, Home range and Social organization. Of the three specimens, an adult female was roosting alone beneath undercut bank of a small stream in the valley bottom of a dense primary forest. The other two specimens (mother and young) were roosting with a third individual (which escaped capture) beneath the undercut bank of another stream in primary upland forest.

Status and Conservation. Not assessed on The IUCN Red List.
