Yates’s Big-eared Bat Micronycteris yatesi French: Micronyctére de Yates / German: Yates-GroRohrblattnase / Spanish: Micronicterio de Yates Taxonomy. Micronycteris yatesi Siles & Brooks, 2013 , “ Bolivia : Chuquisaca Department , Provincia Oropeza, Zurima, 33 km northeast of Sucre ( 18°46’40.2”S , 65°07'40.3"W ). Collected at 1,800 m above sea level.” This species is monotypic. Distribution. Known from a few localities in C & E Bolivia (Zurima in Chuquisaca and Refugio Los Volcanes and Estancia Patuju in Santa Cruz departments); it might be found in W Brazil because some Sanborn’s Big-eared Bats ( Micronycteris sanborni ) from that region might be Yates’s Big-eared Bat. Descriptive notes. Head—body 48-60 mm, tail 7-9-2 mm, ear 15-6-18-2 mm, hindfoot 11-4-11-7 mm, forearm 34-5-36-7 mm. Yates’s Big-eared Bat is medium-sized. As most species of Micronycteris , it has bicolored, long (8-10 mm) dorsal pelage, with hairs having white bases and tawny to brown tips. Ventral fur is completely white on throat and sternal region, but abdominal area is pale buff. Ears are large (15-18 mm), with rounded tips, and their bases are connected by high, notched band. Hindfeet are hairy. Based on DNA sequence data, Yates’s Big-eared Bat can be distinguished from congeners by nucleotide differences that result in unique amino acids in cytochrome-b protein at positions 67 (alanine), 181 (leucine), and 316 (alanine). Habitat. Various Bolivian ecoregions, including Yungas, Cerrado, Chiquitano Dry Forest, and Inter-Andean Dry Forest, with dry forest, humid inner tropics, and seasonally dry subtropics. Yates’s Big-eared Bat occurs in semideciduous savanna, composed of a mosaic of open grassland, to a landscape dominated by moderately dissected valleys and small plains, with largely disturbed or destroyed deciduous dry forest. Food and Feeding. No information. Breeding. No information. Activity patterns. Yates’s Big-eared Bat is nocturnal. Movements, Home range and Social organization. No information. Status and Conservation. Classified as Data Deficient on The [UCN Red List. Consider-Ing its rarity, proven by its low rate of capture and presence in highly vulnerable habitats, Yates’s Big-eared Bat might become threatened in Bolivia and elsewhere. Bibliography.
