( Figures 10–13View FIGURES 10 – 13)

Types. Holotype male from Brazil, state of Paraná, Guaraqueçaba  , Reserva Natural Serra do Itaqui (25 ° 17 ’ 19 ”S; 48 ° 28 ’ 29 ”W), 16.IX. 2007, I. Czisauskas col., deposited in MCN 45294. Paratype female, same data as the holotype, deposited in MCN 45294.

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

Diagnosis. The male of Dipoena guaraquecaba  new species resembles that of D. chickeringi Levi, 1953  (see Levi, 1953: 1, figs. 1–4), but differs in the large conductor, in the trajectory of the sperm duct in the tegulum ( Fig. 10View FIGURES 10 – 13) and in the pattern and shape of the carapace in lateral view ( Fig. 12View FIGURES 10 – 13). The female of Dipoena guaraquecaba  is close to D. tingo Levi, 1963  (see Levi, 1963: 180, fig. 287) by having an anterior, sclerotized area on the epigynum, but differs from it in the smaller sclerotized area ( Fig. 13View FIGURES 10 – 13).
