A New Bat (Genus Pipistrellus)
from Northeastern México
by
Rollin H. Baker
The eastern pipistrelle, Pipistrellus subflavus (Cuvier) in the western part of its range, occurs along the Río Grande and its tributaries as far west as northern Coahuila and Val Verde County, Texas. Specimens from those places represent a heretofore undescribed subspecies which may be named and described as follows:
Pipistrellus subflavus clarus new subspecies
Type.—Female, adult, skin and skull; No. 48270, Univ. Kansas Mus. Nat. Hist.; 2 mi. W Jiménez, el. 850 ft., Coahuila; 19 June 1952; obtained by Rollin H. Baker, original No. 2062.
Range.—Known from northern Coahuila and adjacent parts of southwestern Texas.
Diagnosis.—Size large (see measurements); upper parts pale, near (c) Cinnamon-Buff (capitalized color term after Ridgway, Color Standards and Color Nomenclature, Washington, D. C., 1912); skull large; zygomata expanded laterally.
Comparisons.—Compared with Pipistrellus subflavus subflavus (specimens from Marshall Hall in Maryland, Raleigh in North Carolina, and Barber County in Kansas) P. s. clarus is paler, of approximately equal size, and has the zygomata slightly more expanded laterally. From Pipistrellus subflavus veracrucis (Ward), specimens from 4 km. E Las Vigas, el. 8500 ft., Veracruz, P. s. clarus differs in being larger, paler, and in having a larger skull.
Remarks.—Pipistrellus subflavus clarus is the palest subspecies of the eastern pipistrelle. Of the specimens assigned to clarus (all taken in May and June), only two are sufficiently dark to compare favorably with examples of typical subflavus. A specimen (KU 60296) assigned to P. s. subflavus from Rancho Pano Ayuctle, el. 300 ft., 6 mi. N Gómez Farías, Tamaulipas, is much darker than clarus. A specimen recorded from Devils River, Texas, by V. Bailey (N. Amer. Fauna, 25:211, October 24, 1905) has not been examined by me but presumably is P. s. clarus.
Pipistrellus subflavus clarus was taken along the Río San Diego and the Río Sabinas, both tributaries of the Río Grande, where park-like stands of pecan, cypress, willow and other trees bordered these streams. The species was not found at stock ponds or along stream courses
