Abstract: The first cases of gynandromorphism and teratology are reported in Megacampsomeris prismatica (Smith, 1855); representing the first record of teratology in the tribe Campsomerini and bringing the number of documented cases of gynandromorphism in Scoliidae to eight. Owing to the pronounced sexual dimorphism of this group, three remarkable specimens are described and illustrated: two mosaic gynanders, one affected only in the head, while the other throughout the body, and a teratological male exhibiting an asymmetric fusion of the first two metasomal segments. A review of known cases of gynandromorphism and teratology in Scoliidae is also provided.

Keywords: Aberration, gynandromorphs, hairy flower wasps, malformation, morphology, scoliid, teratology

摘要：本文首次在Megacampsomeris prismatica (Smith, 1855) 报道了雌雄嵌体与畸形案例；其中畸形案例为Campsomerini族首次记录，同时使土蜂科已知的雌雄嵌体记录增至八例。鉴于该类群具有显著的性二型，本文对三号珍贵标本进行了描述与图示：两号镶嵌型雌雄嵌体——其一仅头部受影响，另一则整个虫体均有表现；以及一号畸形雄性标本，其后体前两节呈不对称愈合。文中还提供了土蜂科已知雌雄嵌体与畸形案例的综述。
