A New Bat (Genus Leptonycteris) From Coahuila

A New Bat (Genus Leptonycteris) From Coahuila

In a collection of mammals obtained in Coahuila, Mxico, there is a series of 24 long-nosed bats, Leptonycteris nivalis. These bats have a larger skull and a longer third finger than other bats of this species found to the south of Coahuila. On the basis of these distinctive characters, it seems appropriate to recognize these long-nosed bats from Coahuila as belonging to a new subspecies, named and described as follows: Type.Female, adult, skin and skull, No. 33087, Univ. Kansas Mus. Nat. Hist.; 12 mi. S and 2 mi. E Arteaga, 7500 ft., Coahuila; 11 July 1949; obtained by W. K. Clark, original number 787. Diagnosis.Size large (see measurements); third finger long; color pale, upperparts Hair Brown (capitalized color terms are after Ridgway, Color Standards and Color Nomenclature, Washington, D. C., 1912), underparts Smoke Gray; skull large and broad. Comparisons.From Leptonycteris nivalis nivalis (specimens from Veracruz, Oaxaca, Distrito Federal, Hidalgo, Jalisco, and Sonora), L. n. longala differs as follows: color paler, more whitish and less brownish; third finger longer (longala from Coahuila averaging 111.3 mm.; nivalis from Sonora averaging 91.0, from Jalisco 96.4, from Hidalgo 98.0, from Veracruz 100.0, from Distrito Federal 100.2, and from Oaxaca 98.6); skull larger, breadth of cranium greater (longala from Coahuila averaging 10.7 mm.; nivalis from Sonora 9.8, from Jalisco 9.8, from Hidalgo 9.6, from Veracruz 9.9, from Distrito Federal 9.9, and from Oaxaca 9.8); mastoidal breadth greater (longala from Coahuila averaging 11.6 mm.; nivalis from Sonora 10.5, from Jalisco 10.8, from Hidalgo 10.6, from Veracruz 10.9, from Distrito Federal 10.8, and from Oaxaca 10.7); skull higher (longala from Coahuila averaging 10.0 mm.; nivalis from Sonora 9.3, from Jalisco 9.2, from Hidalgo 9.2, from Veracruz 9.3, from Distrito Federal 9.3, and from Oaxaca 9.1). The average of each dimension of longala listed above exceeds the maximum of the corresponding dimension in nivalis. ......Buy Now (To Read More)
