Table 2. Summary of diagnostic quantitative characters of external and skull morphology between New World Eptesicus (NWE), Old World Eptesicus (OWE), and Histiotus species. Mean values are presented in millimeters for “forearm length”, “ear length”, “tragus length”, and the ratio between “greatest length of skull” (GLS) and“breadth across molars” (BAM). The number of specimens analyzed (N) for each measurement is provided in parentheses.
