Taxonomy.
Tonatia evotis W. B. Davis & D. C. Carter, 1978
,
“
25 km
. SSW Puerto Barrios,
75 m
., department of
Izabal
,
Guatemala
.”
Although originally described in the genus
Tonatia, T. E. Lee
and collaborators in 2002 reassigned
evotis
to
Lophostoma
after phylogenetic analysis.
Distribution.
S
Mexico
in S
Veracruz
, NE
Oaxaca
, S
Yucatan
Peninsula, and
Chiapas
, also in
Belize
, N
Guatemala
, and N
Honduras
.
Descriptive notes.
Head-body 49-70 mm, tail 11-18 mm, ear 31-35 mm, hindfoot 13
16 mm
, forearm 47-53 mm; weight 14-23 g. Davis’s Round-eared Bat is medium-sized compared with other species of
Lophostoma
. Its sister species, the White-throated Roundcared Bat (
L. silvicola
), is larger and has more powerful teeth and two white patchesat bases of ears. Fur of Davis’s Round-eared Batis uniformly pale gray to dark gray. There is very little contrast between dorsum and venter. There are no pale patches in bases of ears. Fur is short and sparse. Tail is short and completely embedded in uropatagium. Noseleaf is simple and triangular, and horseshoe or lower end ofnoseleat is fused with upper lip. Numerous small warts cover chin, and two larger pads form V-shaped groove. Face is nearly naked. Eyes are small and dark brown. Ears curl backward when held by a human. Davis’s Round-eared Bats have four upper and two lower incisors.
Habitat.
Relatively intact humid tropical forests rainforests at elevations below
100 m
. Davis's Round-eared Bat probably roosts in termite nests, similar to other species of
Lophostoma
.
Food and Feeding.
Stomachs of four Davis's Round-eared Bats collected in southern
Mexico
contained remains of katydids and beetles.
Breeding.
Female Davis’s Round-eared Bats carry one fetus. Births seem to be synchronized around onset of rainy season.

Status and Conservation.
Classified as Least Concern on The [UCN Red List. Because Davis’s Round-eared Bats are sensitive to habitat disturbance by humans and have a relatively small distribution, they have been federally listed as threatened in
Mexico
.
