Second record of Lasiurus ebenus (Chiroptera, Vespertilionidae), with comments on its taxonomic status

Abstract

Lasiurus ebenus was known only from the holotype, which was collected in 1991, in an Atlantic Forest remnant of Ilha do Cardoso State Park, southeastern Brazil. The species was described based on qualitative and quantitative morphological features. Since its original description, based on a single individual, the taxonomic status of Lasiurus ebenus has been questioned. Here we report a second record for the species that comes from Carlos Botelho State Park, São Paulo, ca. 100 km north from the type locality. This new record allowed us to confirm the validity of the species, by presenting additional data that fits in the distinction from sympatric congeners proposed on the original description of L. ebenus.

First record of Lasiurus egregius (Peters, 1870) (Chiroptera, Vespertilionidae) in Paraná state, southern Brazil

“…The good maneuverability and high capacity for echolocation are characteristics that decrease the likelihood of its capture (López-Baucells et al 2014). Another factor that can contribute to its perceived rarity is that individuals of genus Lasiurus are usually captured over water bodies (Cláudio et al 2018), which are hardly ever sampled in studies of bat assemblages (López-Baucells et al 2014). Mist netting over water bodies increases the probability of capturing insectivorous bats (Costa et al 2012), and, therefore, it should be a more-used protocol in the study bat biodiversity.…”

“…Morphometry of the specimen of Lasiurus egregius captured in the RNSM (present study), and data from other species of the genus occurring in Brazil. Data sources: L. egregius - López-Baucells et al (2014); L. blossevillii -Simons and Voss (1998); Rodrigues and Ribas (2011); Cláudio et al (2018); Verde et al (2017); L. cinereus - Shump and Shumpz (1982); Myers and Wetzel (1983); Cláudio et al (2018);L. ega -Myers and Wetzel (1983); Bolzon (2008); Leal and Gomes-Silva (2015); Cláudio et al (2018);L.…”

Lasiurus villosissimus (Chiroptera: Vespertilionidae)

“…These include one species of yellow bat (southern yellow bat L. ega) and seven species of red bats (big red bat L. egregius, hairytailed bat L. ebenus, Arequipa red bat L. arequipae, greater red bat L. atratus, southern red bat L. blossevillii, Tacarcunan bat L. castaneus, and cinnamon red bat L. varius). Lasiurus villosissimus can be distinguished from L. ebenus by its almost entirely black pelage, and from L. ega and L. egregius by their yellowish or reddish pelage that lacks frosting (Díaz et al 2016(Díaz et al , 2021Cláudio et al 2018).…”

The bat fauna (Mammalia: Chiroptera) of Carlos Botelho State Park, Atlantic Forest of Southeastern Brazil, including new distribution records for the state of São Paulo

“…Our specimen represents the second record of. L. ebenus since its description (see Cláudio et al 2018). The species was previously known only from its type locality, the Ilha do Cardoso State Park, also in São Paulo state (Fazzolari-Corrêa 1994), which is about 100 km away from PECB.…”
