Group adisi

Diagnosis. The adisi group differs from the quadrivittata group by the palp with a absence of prolaterally modified cymbial spine, transversal triangular ventral tegular projection with wide base and pointed apex, embolus short, with a basal embolar apophysis; female epigynum with lateral borders of anterior field inconspicuous and internally with short copulatory ducts ( Figs 1F, J ; 3G–I ; 4C, F ; 5G, H ; 6C, F ; 7C, F ; 8C ).

Composition. O. adisi , O. lupercioi sp. nov., O. chica sp. nov., O. duovizinhense sp. nov. and O. aparecida sp. nov.
