Histiotus stocki (Stirton 1931)—Stock's Snub-nosed BatRegional Pleistocene distribution of Histiotus stocki

Synonyms. Simonycteris stocki.

Kurtén and Anderson (1980) noted that Stirton hadn't compared the holotype to Histiotus when he named the species Simonycteris stocki; on the basis of a personal communication with Karl Koopman, they transferred the taxon to Histiotus.

Sites.

Late Blancan: Cal Tech (Lindsay 1984); Curtis Ranch (Morgan and White 2005, as Simonycteris stocki).

Literature.

Kurtén and Anderson 1980; Lindsay 1984; Morgan and White 2005.

Lasiurus sp.—Hairy-tailed BatsPleistocene distribution of Lasiurus sp.

Members of the genus Lasiurus sometimes are called tree bats from their habit of roosting in trees rather than caves, crevices, or dwellings. The often colorful fur blends nicely with foliage and often allows them to go unnoticed. Several species occur in our region, rendering species identification difficult at times with fragmentary material.

Sites.

Wisconsin: Glen Abbey, Bonita (Majors 1993: cf. gen.).

Late Wisconsin/Holocene: Balcony Room (Harris 1993c).

Literature. Harris 1993c; Majors 1993.

Lasiurus borealis (Müller 1776)—Eastern Red BatRegional Pleistocene distribution of Lasiurus borealis.

The Eastern and Western red bats meet in our region. It's doubtful that the two species (L. borealis and L. bossevillii) can be told apart on fragmentary fossil material. Carlsbad Caverns is in the area most likely to support the Eastern Red Bat.

Sites.

Late Wisconsin/Holocene: Carlsbad Cavern (Baker 1963).

Literature. Baker 1963.

Lasiurus cinereus (Palisot de Beauvois 1796)—Hoary BatPleistocene distribution of Lasiurus cinereus.

Hoary Bats migrate through the region today, with some summering in the higher elevations. Individuals may be found almost anywhere during migration.

Sites.

Mid Wisconsin: Pendejo Cave (Harris 2003).

Mid/Late Wisconsin: Rancho La Brea (Akersten et al. 1979).

Late Wisconsin: Harris' Pocket (Harris 1970a: cf.).

Late Wisconsin/Holocene: Carlsbad Cavern (Baker 1963).

Literature. Baker 1963; Harris 1970a, 2003; Akersten et al. 1979.
