Dipoena guaraquecaba new species

( 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. 10 ) and in the pattern and shape of the carapace in lateral view ( Fig. 12 ). 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. 13 ).
