Abstract
Two new records of gynandromorphs in Xylocopa Latreille, 1802 (Hymenoptera, Apidae). Gynandromorphs are deviant morphological individuals with genetically distinct male and female tissues. Records of sex anomalies seems to be important to better understand the mechanisms regulating phenotypic expression. Herein, two new cases of gynandromorphs in carpenter bee species of Xylocopa from Brazil are described and figured: a mixed gynandromorph of the X. (Neoxylocopa) brasilianorum (Linnaeus, 1767) from São Paulo and a bilateral gynandromorph of the X. (Neoxylocopa) ordinaria Smith, 1874Smith, F. 1874. Monograph of the genus Xylocopa, Latr. Transactions of the American Entomological Society, (1874): 247-307. from Sergipe.
