Diagnosis Males of Jambu gen. nov. differs from those of all known Theraphosidae by the combined presence of type IV urticating setae and a spatulated, wide, paraembolic apophysis on the palpal bulb. Also, males of Jambu have a pronounced tegular apophysis on palpal bulb. The male tibial apophysis is very sclerotized, composed of two convergent branches, the larger with a short and strong apical spine. Females differ from those of other Theraphosidae by the combination of type IV urticating setae and spermathecae morphology with single lamp-shaped or heart-shaped receptacle. Both sexes have dorsal abdominal patterns of dark brown spots on a lighter brown background. Etymology The genus is named after the word ‘Jambu’ which refers to a native plant from Brazilian Amazonia used as an ingredient in traditional gastronomy as Tacacá soup and as a natural analgesic. The gender is neuter. Composition Jambu paru gen. et sp. nov , Jambu manoa gen. et sp. nov. , Jambu butantan ( Pérez-Miles, 1998 ) gen. et comb. nov. Distribution Northern Brazil , Amazon Basin.
