Sexual anomalies, particularly gynandromorphism and intersexuality, have been documented across a wide range of invertebrate groups including insects. This study reports the first record of gynandromorphism in a phalangopsid cricket, Endecous (Notendecous) potiguar. A detailed morphological characterization of the anomalous specimen is provided, with its traits compared to those of conspecific males and females collected concurrently from the same cave in which the anomalous individual was discovered. The specimen displays a striking mosaic of male and female features, including a malformed phallic complex and ovipositor. Beyond documenting this rare condition, these findings may provide a foundation for future investigations into the evolution, homology, and ontogeny of sexual traits particularly within crickets.
