Identification Note For ease I have included the identification block here to see how that compares with the original description and my explanation of that description. Also note that over time more research is done and more definite features are added that change what the original descriptions may have — but it is important to note the original author and their descriptions.

Disclaimer: A lot of work goes into trying to identify and ensure accurate identifications are made and that the listed Descriptions, Sizes, Habitats and Distribution information is as accurate and valid as possible. Unfortunately, information in this arena is ever changing and as such no guarantee can be offered that it is correct or currently valid — as a result the information is provided as a guide, and it is always suggested that you do a little research to ensure you have the latest and most accurate information.
