Abstract
An invasive armored scale, Pseudaulacaspis rubra (Maskell, 1898) (Hemiptera: Coccomorpha: Di¬aspididae), was detected in the Western Hemisphere for the frst time in January 2025. This species was found in abundance on mature mango trees (Mangifera indica L.) (Anacardiaceae) planted in the landscape in sub¬urban Miami-Dade County, Florida, USA. Habitus and slide-mounted images are provided. A natural enemy, the larva of a Cybocephalus sp. (Coleoptera: Cybocephalidae) beetle, was observed feeding on an adult female under the test. Herein we provide an updated species diagnosis for P. rubra with discussion on morphological variation and a key to slide-mounted adult females of four Pseudaulacaspis MacGillivray species present in Florida and two species of Albastaspis MacGillivray intercepted in Florida, with illustrations of each. We also provide host data for all Florida specimens of Pseudaulacaspis and Albastaspis in the Florida State Collection of Arthropods as well as novel sequence data for two species (P. rubra and Albastaspis coloisuvae (Williams and Watson)) treated in the study.
