First Record of Gynandromorphism in Augochlora phoemonoe and an Updated List of Gynandromorphs in Halictinae

We report here a new case of gynandromorphism in Augochlora phoemonoe, collected in Morro Redondo, Rio Grande do Sul. The specimen exhibits a combination of male and female morphological characters distributed asymmetrically across the head and mesosoma, the metasoma is entirely male, classifying it as a mixed-type or mosaic gynandromorph. This is among the few records of this condition in the tribe Augochlorini, contributing to the understanding of morphological diversity and the occurrence of sexual anomalies in Halictinae. Currently, 27 cases of gynandromorphism are known for the subfamily, with most of them being mosaic type.
