True, but while they are nearly impossible to distinguish without looking at male genitalia, they can be separated by their geographic range: Cybister occidentalis is found primarily in the Bahamas and Cuba, and in Florida its presence is restricted to the extreme southern portion (such as the Keys). It should not be present in Kissimmee |
