Abstract: 

Herein, we describe the first case of intersexuality in the Hydropsini tribe. After examination of 720 specimens of Helicops infrataeniatus Jan, 1865, we discovered one individual that presented feminine and masculine reproductive features. The specimen was 619 mm long, with seven follicles in secondary stage, of different shapes and sizes, and a hemipenis with 13.32 and 13.57 mm in length. The general shape of this organ is similar to that observed in males, although it is smaller and does not present conspicuous spines along its body. Deformities found in feminine and masculine structures suggest that this specimen might not be reproductively functional.
