A case of gynandromorphism in Amblyomma oblongoguttatum (Acari: Ixodidae).
During a survey conducted from August to November 1998 to ticks associated with dogs in the rural area of Uruará, in the state of Para, Eastern Amazon region of Brazil, we collected one gynandromorph specimen out of 18 Amblyomma oblongoguttatum Koch specimens collected from dogs. It is a perfect bipartite gynandromorph, reported in this species for the first time.
