Descriptive notes. Head-body 56-66 mm (tailless), ear 14-17 mm, forearm 41-45 mm; weight 18 g. The Perla Yellowshouldered Bat is medium-sized, externally similar to Luis’s Yellow-shouldered Bat (S. wisi) and the Northern Yellowshouldered Bat ( S. parvidens ). Dorsal fur is grayish brown with four-banded hairs; sometimes shoulders and neck of adults (especially males) have yellow or reddish patch; ventral fur is paler, with tricolored hairs. The Perla Yellow-shouldered Bat is characterized by a spherical skull, noticeably round and robust, with pronounced curved zygomatic arches. Lower molars have poorly defined cusps toward tongue.

Habitat. [.owlands and adjacent slopes in primary and secondary humid tropical forests on western side of the Andes at elevations of 35-700 m.

Food and Feeding. There is no specific information available for this species, but yellow-shouldered bats feed on fruits, being largely dependent on Solanum (Solanaceae) and Piper (Piperaceae) on the lowlands. The distinct shape of the skull of the Perla Yellow-shouldered Bat suggests that it might also be divergent in its feeding behavior.

Breeding. No information.

Activity patterns. The Perla Yellow-shouldered Bat is nocturnal.

Movements, Home range and Social organization. No information.

Status and Conservation. Classified as Data Deficient on The IUCN Red List. The Perla Yellow-shouldered Bat is rare and poorly known, with a restricted distribution. There is no information available on population size, and therefore its conservation status is unknown. Deforestation and mining are probably its main threats. Records came from two protected areas: Cotacachi-Cayapas Ecological Reserve and La Perla Protected Forest. Nevertheless, La Perla is an isolated patch of Ecuadorean Choco forest consisting of only 226 ha of primary forest surrounded by vast expanses of monocultures consisting mostly of grazing lands, oil palms, and banana trees.
