Abstract:

Variation was evaluated in 67 specimens of the spotted bat Euderma maculatum from throughout its range. There was significant secondary sexual dimorphism in size for one of 16 characters (females were larger than males in length of forearm). Because of small samples, specimens were grouped into four regional populations. There was significant interpopulation heterogeneity in 10 of 16 characters; the southern population (from Texas to Queretaro, Mexico) was significantly larger than the others in length of ear, and the western population (from California to Utah) was significantly smaller than the others in length of forearm. Populations were widely separated in multivariate analyses.
