This key does not include all taxa in the group. Therefore, there is a chance that a species that is not represented in the tool will key out as one that is (a false positive identification). For this reason, identifications should always be checked against information on the species pages and compared with authoritatively identified reference specimens for further assessment.

Even though we have made every effort to provide accurate and updated information, the authors, USDA ARS, and USDA APHIS ITP specifically disclaim all legal liability with respect to the accuracy, completeness, or usefulness of any information contained in Key to Commonly Intercepted Aspidiotini. The authors and the institutions involved shall assume no legal liability for any damages, including direct, indirect, consequential, compensatory, special, punitive, or incidental damages arising from or relating to the use of Key to Commonly Intercepted Aspidiotini or the information and materials provided by or linked to from Key to Commonly Intercepted Aspidiotini.
