Well-known examples of such a discrepancy are the Palaearctic vespertilionid bats of the Myotis mystacinus morphogroup (Ruedi & Mayer 2001, von Helversen et al.
2015: Bat diversity in the Simandou Mountain Range of Guinea, with the description of a new white-winged vespertilionid.
We noted that movements of vespertilionids did not appear limited during any configuration of the antenna, similar to observations by Britzke et al.
We observed that nontarget vespertilionid bats passed through the antenna in any configuration and were captured regularly from 26 April-14 June 2014 in a harp trap at the cave.
Gleaning also may be occurring with other prey such as moths, especially in vespertilionids adapted for slow, maneuverable flight, often within cluttered understory (Fenton, 1990; Norberg, 1994).
Thirteen species of vespertilionid bats occur in southern Illinois.
In the absence of male-biased dimorphism and in the presence of high involvement of the female vespertilionids
with their offspring, the sexual size dimorphism reported in this paper indicates a strong influence of ecological factors (natural selection) for dimorphism.
The western small-footed myotis, Myotis ciliolabrum (Merriam 1886), is a small vespertilionid
that occurs over much of western North America from central British Columbia, southern Alberta, and southwestern Saskatchewan, Canada, southward to Chihuahua, Coahuila, and Zacatecas, Mexico (Holloway and Barclay 2001).

was confirmed by the present results.
1978: Sexual dimorphism in size of vespertilionid
We compared the genetic diversity of CoVs isolated from rhinolophids and vespertilionids
and the corresponding diversity among bat taxa by using the index of nucleotide diversity 0t) described by Nei (28) in Arlequin version 3.
This is particularly marked in the vespertilionids
In some vespertilionids
(such as Eptesicus, Perimyotis, Myotis, Lasionycteris), the ulna has a small or absent olecranon process, is unfused at the semilunar notch but fused slightly more distally along the shaft beneath or just distal to the semilunar notch, and contributes its own separate, small articular facet to the semilunar notch.
Moreover, some insectivorous bats such as molossids and vespertilionids
are difficult to capture with mist-nets (Handley, 1967; Reis and Muller, 1995).
On the eastern side, in contrast, the northern site was dominated by vespertilionids
and phyllostomids; the proportion of vespertilionids
also diminished southward.
