description: 128. Soriano’s Yellow-shouldered Bat <i>Sturnira sorianoi</i> <b>French:</b> Sturnire de Soriano / <b>German:</b> Soriano-Gelbschulterfledermaus / <b>Spanish:</b> Sturniro de Soriano <b>Taxonomy.</b> Sturnira sorianoi Sanchez-Hernandez, Romero-Almaraz &amp; Schnell, 2005, “ Venezuela, Asentamiento Monterrey, 8 km NNE from Mérida, El Valle, 2300 m, 8°37'N, 71°10'W.” Sturnira sorianoi has not been included in recent phylogenetic studies. Future inclusion in such studies could clarify its taxo-nomic status and relationships to S. erythromos and S. ludovici. Monotypic. <b>Distribution.</b> Known from isolated localities in NW Venezuela (Mérida State) and E Bolivia (Santa Cruz Department). <b>Descriptive notes.</b> Head-body 57-69 mm (tailless), ear 15-18 mm, hindfoot 13-14 mm, forearm 42-8-43.7 mm; weight 17-21 g. Soriano’s Yellow-shouldered Batis medium-sized. Dorsalfur is dense, silky, and pale gray; venter is pale brown. Face is darker, almost blackish. Should glands (epaulettes) are indistinguishable. Dorsal hairs are 8 mm long and have four bands: whitish bases, blackish subbasal bands, brown and whitish subterminal bands, and pale gray or brown tips. Ventral hairs are tricolored or bicolored: white bases, blackish medial bands, and pale brown tips. Wing membrane, noseleaf, and ears are blackish. Noseleaf is triangular, 7 mm long and 4 mm wide at base. Free margin of tail membrane has dense short hairs. Skull is long and robust, with square and short face. Supraorbital border and sagittal and occipital crests are well developed. Zygomatic arches are thin and bowed outward. I' and I? are bicuspid, with internal lobe larger than external lobe. Lower incisors are trilobed. M, and M,are smooth, with shallow groove between lingual cusps. <b>Habitat.</b> Cloudy forests, mainly evergreen with an irregular canopy supporting epiphytes (Bromeliaceae, Orchidaceae, Araceae, Piperaceae, and pteridophytes) and arborescent ferns (Cyatheaceae), at elevations of 1700-3000 m in Venezuelan Andes and lowland drier Bosque Chiquitano in eastern Bolivia below 1000 m. S. Anderson in 1997 described these Bolivian habitats as “intermediate between the wet Amazonian forests to the north and the dry Chacoan forests to the south.” <b>Food and Feeding.</b> Soriano’s Yellow-shouldered Bat is expected to be mainly frugivorous, maybe eating some pollen, nectar, and insects. <b>Breeding.</b> No information. <b>Activity patterns.</b> Soriano’s Yellow-shouldered Bat is nocturnal. <b>Movements, Home range and Social organization.</b> No information. <b>Status and Conservation.</b> Classified as Data Deficient on The IUCN Red List. Soriano’s Yellow-shouldered Bat has a disjunct distribution, based on known records, and there is taxonomic uncertainty aboutits relationships to other species of Sturnira. <b>Bibliography.</b> Anderson (1997), Castafo et al.
