ABSTRACT
Gynandromorphism or intersexuality is a rare condition where the individual has male and female features. In this report we described two imagoes of Farrodes xingu Domínguez et al. (1996) from Brazil presenting intersex traits. We considered the arranged sexual characters as antero-posterior and bilateral. One individual has a male head, abdomen full of eggs and the subgenital plate with a malformed outset of penes (antero-posterior), while the other individual has half of the head with a male-like turbinate eye and the other half with a regular female-like one, and with malformed male genitalia (bilateral).
