Poecilia waiapi, a new poeciliid from the Jari river drainage, northern Brazil (Cyprinodontiformes: Cyprinodontoidei)Poecilia waiapi, new species, is described from the lower Jari river drainage, in northern Brazil. It is hypothesized to be closely related to P. branneri, P. minima and P. sarrafae by sharing eight apomorphic conditions. Poecilia waiapi differs from all of its congeners by the presence of vertical dark gray bars on the flank in males (vs. bars absent in P. bifurca, P. picta and P. parae; vertical pale gray bars in P. sarrafae, P. minima and P. branneri); post-humeral blotch densely pigmented (vs. post-humeral blotch absent in P. branneri, post-humeral blotch slightly pigmented in P. sarrafae, P. minima, P. picta, P. bifurca, P. parae).
