Burton's Yellow-shouldered Bat

Sturnira burtonlimi

French: Sturnire de Burton Lim / German: Burton-Gelbschulterfledermaus / Spanish: Sturniro de Burton Lim

Other common names: Burton Lim's Yellow-shouldered Bat

Taxonomy. Sturnira burtonlimi Velazco & Patterson, 2014,

“Ojo de Agua, 2 km N of Santa Clara, Chiriqui, Panama, approximately 8°42’N, 82°45’W, 1500m.”

Sturnira burtonlimi was previously confused with S. ludovici and S. hondurensis . Molecular and morphological analyses identified it as a distinct species. Monotypic.

Distribution. Known only from two localities, one in C Costa Rica (Cartago Province) and the other in W Panama (type locality).

Descriptive notes. Head—body 70-72 mm (tailless), ear 15 mm, hindfoot 14 mm, forearm 44 mm; weight 19 g (all measurements from two specimens). Burton's Yellow-shouldered Bat is medium-sized, similar to the Honduran Yellow-shouldered Bat ( S. hondurensis). Dorsal fur is dark brown. Dorsal hairs have four bands, with short pale gray base (c.10% of the length of each hair), long dark gray band (c.40%), long pale gray band (c.40%), and short dark brown tip (c.10%). Ventral fur is dark brown and tricolored, with narrow pale gray base, long dark brown subterminal band (c.45% of each hair), and long gray terminal band (c.45%). Furis long and woolly: 7 mm between shoulders and 5 mm on chest. Proximal part of forearm is densely furred with short hairs. Wing membranes of are dark brown. Dorsal surfaces of femur and tibia are densely covered with long hairs; dorsal surfaces of feet are densely covered with short hairs. Tail membrane is very short and well-furred with long hairs. I' is procumbent and atleast twice the height of I, and I, and I, are bicuspidate and subequalin size. Lingual cuspids (metaconid and entoconid) of M, and M, are poorly defined and are not separated by deep notch.

Habitat. Collected in pre-montane forest near coffee fields at elevations of 1290-1500 m. Based on E. Dinerstein’s 1986 ecological study on the Costa Rican Highland Yellow-shouldered Bat ( S. ludovici) that could have actually been Burton’s Yellow-shouldered Bat, fruits of abundant second-growth shrubs are more frequently eaten than mature forest plants.

Food and Feeding. Dinerstein stated that Burton’s Yellow-shouldered Bat consumes fruits of 27 plant species, including Solanum spp. ( Solanaceae), Piperspp., and P. umbellatum ( Piperaceae).

Breeding. Dinerstein stated that Burton’s Yellow-shouldered Bat has birth peaks in April-May and September—October.

Activity patterns. Burton's Yellow-shouldered Bat is nocturnal.

Movements, Home range and Social organization. No information.

Status and Conservation. Classified as Data Deficient on The [UCN Red List. Although Burton’s Yellow-shouldered Bat has a restricted distribution, there are no major conservation threats in this area.
