Taxonomy
Plecotus gaisleri was described as a new subspecies of the Canary big-eared bat (P. teneriffae) in 2004 by Petr Benda, who gave it the trinomen of Plecotus teneriffae gaisleri. The holotype had been collected approximately 8 km (5.0 mi) southwest of Massah, Libya in 2002. The eponym for the species name "gaisleri" was Jiří Gaisler, who "significantly contributed to the knowledge of the North African bat fauna". A 2007 study concluded that it should be considered a full species, P. gaisleri, based on the magnitude of genetic divergence.

Description
Plecotus gaisleri is a medium-sized member of its genus, with a forearm length of 37–42 mm (1.5–1.7 in). Individuals weigh approximately 7–10 g (0.25–0.35 oz).

Biology and ecology
It is nocturnal, foraging for its prey at night or shortly before sunset. It mostly consumes large- and medium-sized moths, though also consumes some beetles and flies. Its reproduction is not well known, though it likely has a litter size of one individual, breeds seasonally, and has only one breeding season annually. Its predators include barn owls and Pharaoh eagle-owls.

Range and habitat
Plecotus gaisleri is known from areas of Libya with a Mediterranean climate. In 2004, its known distribution was limited to an area of about 10,000 km2 (3,900 sq mi), encompassing mountainous and coastal regions. It is now additionally known from Morocco, Algeria, and Tunisia.
