title: Description of two new cases of gynandromorphism in Paratrigona Schwarz and Augochlora Smith (Hymenoptera: Apidae and Halictidae).
abstract: Two new records of gynandromorphism in bees are described and illustrated for Paratrigona glabella and Augochlora amphitrite. The specimens show a mixture of male and female features, complete in Augochlora and on head and mesosoma in Paratrigona. Including the specimen described herein, gynandromorphs are now known for a total of three species in Meliponini bees and three species in Augochlorini bees.
