( Figures 23–27View FIGURES 23 – 27)

Types. Holotype male from Brazil, state of Paraná, Foz do Iguaçu, Parque Nacional do Foz do Iguaçu (25 ° 36 ’S; 54 ° 25 ’W), 03– 12.III. 2002, Equipe Biota col., deposited in MCN 48921. Paratype female, same data as the holotype, deposited in MCN 48922.

Etymology. The specific name is a noun in apposition, taken from the type locality.

Diagnosis. The male of Dipoena fozdoiguacuensis  new species resembles that of D. tiro Levi, 1963  (see Levi, 1963: 171, fig. 227) in the median apophysis with a projection ( Fig. 23View FIGURES 23 – 27) and in the pattern and shape of the carapace in lateral view ( Fig. 25View FIGURES 23 – 27), but differs in the projection in D. fozdoiguacuensis  more ventrally positioned and the larger embolus ( Fig. 23View FIGURES 23 – 27). The female of Dipoena fozdoiguacuensis  is close to D. tiro Levi, 1963  (see Levi, 1963: 171, fig. 225, 226), but differs from it in the pattern and shape of the epigynum in ventral view, by circular copulatory opening ( Fig. 26View FIGURES 23 – 27) and in the circular first spermathecae ( Fig. 27View FIGURES 23 – 27).
