Vianaleg., deposited in MACN-Ar.  Two malesand two females paratypeswith same data of the holotype, deposited in IBSP 279633.   Etymology.The specific epithet is a toponymic in apposition and refers to the typelocality.   Diagnosis. Males of  Otoniela tigre  sp. nov.resemble those  O. quadrivittataand  O. negrinho  sp. nov.by the precense of pointed ventral tegular projection (see Brescovit 1997a: 159, figs 136, 137; Figs 9C, 10G, H; 11C, D). They differ from others species of the  quadrivittatagroup by the prolaterally transversal short ventral tegular projection, long retrolateral patellar apophysis ( Figs 9C–E; 10C–H). Retrolaterally ventral tegular projection in  O. quadrivittata(see Brescovit 1997a: 159, figs 136, 137); transversal ventral tegular projection distally larger and median apophysis with more accentuated apical curvature in  O. negrinho  sp. nov.( Figs 11C–E). Females resemble those of  O. quadrivittata(see Brescovit, 1997a, figs 138, 139) and  O. negrinho  sp. nov.by the united spermathecae in the anterior region of the vulva ( Figs 9F, G; 11G, H). They differ by the anterior third of copulatory ducts narrowed ( Fig. 9G). Long copulatory ducts laterally inserted on the spermathecae in  O. quadrivittata(see Brescovit, 1997a, figs 138, 139) and wide opening of the copulatory ducts in  O. negrinho  sp. nov.( Fig. 11H).   Description. Male(MACN-Ar).
