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).
