Extensions of Known Ranges

of Mexican Bats

BY

SYDNEY ANDERSON

Incidental to studies of speciation of North American mammals,
made possible by assistance from the National Science Foundation
and the Kansas University Endowment Association, a number of
bats have been taken beyond the limits of their previously known
geographic ranges. Pending the completion of more detailed
faunal accounts, these notes are published so that the distributional
records will be available to interested students of Mexican mammals.

Many of these bats are essentially tropical and the new records
here reported, extend the known geographic ranges to the northward
on either the east or the west coast of Mexico. Continued
collecting, especially by the intensive application of a variety of
methods including the use of mist nets, in the northern parts of the
zone of tropical vegetation can be expected to yield other species of
tropical bats beyond the limits of the ranges now known. Catalogue
numbers cited in parentheses are those of the Museum of Natural
History.

Chilonycteris psilotis Dobson.—Six specimens (36426-36431)
taken 7 mi. W and ½ mi. S Santiago, at sea level, Colima, by J. R.
Alcorn, on March 17, 1950, extend the known range of this species
330 miles westward from the most northwestern recorded occurrence
at Alpuyeca, Morelos (Davis and Russell, 1952:234). Use of
the name psilotis is explained by de la Torre (1955:697).

Chilonycteris parnellii mexicana Miller.—One specimen (54934)
from 10 mi. W, 2 mi. S Piedra, 1200 ft., Tamaulipas, taken by Gerd
H. Heinrich, on June 13, 1953, extends the known range of this species
76 miles east-northeast (Goodwin, 1954:4), previously the most
northern recorded occurrence in northeastern Mexico. Thirty other
specimens have been taken from four additional localities between
El Pachón and the place 10 mi. W, 2 mi. S Piedra.

Pteronotus davyi fulvus (Thomas).—Ten specimens (57525-57534)
from Rancho Santa Rosa, 25 km. N, 13 km. W Cd. Victoria,
260 meters, Tamaulipas, taken by W. Schaldach, V. Grissino, and
R. Grimsley, from December 26, 1953, to January 5, 1954, extend
the known range of this species 360 miles northward from Mirador,
Veracruz (Davis and Russell, 1952:235). Another specimen from
[Pg 350]
Tamaulipas in our collection is from Rancho Pano Ayuctle, 8 mi. N
Gómez Fárias, 300 feet.

Glossophaga soricina leachii (Gray).—Two specimens (54942-54943)
from 16 mi. W, 3 mi. S Piedra, Tamaulipas, taken by Gerd
H. Heinrich, on June 15, 1953, extend the known range of this species
on the Gulf Coast of Mexico northward 60 miles from 5 mi. NE
Antiguo Morelos, near El Pachón, Tamaulipas (de la Torre, 1954:114).

Anoura geoffroyi lasiopyga (Peters).—Three specimens (36574-36576)
from 2 mi. SE Jalcocotán, 3000 ft., Nayarit, the first records
for the state, taken by J. R. Alcorn, on February 15, 1950, extend the
known range of the species 50 miles northward from San Sebástian,
Jalisco (Sanborn, 1933:27).

Choeronycteris mexicana Tschudi.—Three specimens (60176-60178)
from 4 km. N Joya Verde, near Huisachal, 4000 ft., Tamaulipas,
taken by W. Schaldach, on July 17, 1954, extend the known
range of this species eastward into the state of Tamaulipas. Eastern
marginal records in northeastern Mexico were 1 mi. S and 4 mi.
W Bella Unión, 7000 ft., Coahuila (Baker, 1956:174), and Hacienda
Capulín, San Luis Potosí (Dalquest, 1953:27).

Centurio senex Gray.—One specimen (54958) from 14 mi. W, 3
mi. S Piedra, Tamaulipas, extends the known range of the species
58 miles northward from Pano Ayuctle, near Gómez Fárias, Tamaulipas
(de la Torre, 1954:114).

Natalus mexicanus saturatus Dalquest and Hall.—Two specimens
(54999-55000) from the Sierra de Tamaulipas, 14 mi. W, 3 mi. S
Piedra, Tamaulipas, taken by Gerd H. Heinrich, on June 12, 1953,
extend the known range of this species 61 miles northward from El
Pachón, Tamaulipas (Goodwin, 1954:5). Forty-one other specimens
have been taken from three localities between El Pachón and
the new record station mentioned above.

Rhogeëssa parvula tumida H. Allen.—One specimen (55192)
from 4 mi. N La Pesca, Tamaulipas, taken by Gerd H. Heinrich, on
May 24, 1953, extends the known range of the species on the east
coast of Mexico northward 115 miles from 10 kms. WSW Ebano,
Veracruz (Dalquest, 1953:58), and also northeastward 115 miles
from Santa Maria, Tamaulipas (Goodwin, 1954:6). Another new
marginal locality for this species, represented by 39 specimens in
our collection, is 10 mi. W, 2 mi. S Piedra, 1200 ft., Tamaulipas.

Baeodon alleni (Thomas).—A specimen (68773) from 6 mi. W
and 2 mi. N Nejapa, Oaxaca, taken by A. A. Alcorn, on August 6,
[Pg 351]
1955, extends the known range of this species southeastward 100
miles from Cuicatlán, 590 meters, Oaxaca (Hall, 1955:2). Until
recently this species was known from the type locality only.

Lasiurus borealis ornatus Hall.—Sixteen specimens (55325-55340)
from near Piedra, 1200 to 1400 ft., Tamaulipas (1 from 10 mi. W,
2 mi. S; 1 from 14 mi. W, 3 mi. S; and 14 from 16 mi. W, 3 mi. S
Piedra) tend to fill a gap in the known distribution of this species.
Previously it was known from Matamoros, Tamaulipas (Miller,
1897:108), to the north and from Bledos, San Luis Potosí (Dalquest,
1953:61), to the south. Assignment to the subspecies L. b.
ornatus is tentative and is based primarily on the scanty cover of
hair toward the margin of the interfemoral membrane and scanty
cover of hair on the ventral surface of the membrane along the
forearm. Adequate comparative material of L. b. ornatus from
southern Mexico is not available.
