( Figures 19–22View FIGURES 19 – 22)

Types. Holotype male from Brazil, state of Mato Grosso do Sul, Bonito (21 °07’ 15 ”S; 56 ° 28 ’ 55 ”W), 14– 23.X. 2002, Equipe Biota col., deposited in MCN 48954. Paratype female and male, same data as the holotype, deposited in MCN 48953.

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

Diagnosis. The male of Dipoena bonitensis  new species resembles that of D. kuyuwini Levi, 1963  (see Levi, 1963: 156, fig. 108) in the projection in tegulum ( Fig. 19View FIGURES 19 – 22), but differs in the larger projection of D. bonitensis  ( Fig. 19View FIGURES 19 – 22). The female of Dipoena bonitensis  is close to D. kuyuwini  (see Levi, 1963: 156, figs. 106, 107) in the presence of posterior sclerotized plate developed ( Fig. 22View FIGURES 19 – 22), but differs from it in the wider copulatory opening ( Fig. 22View FIGURES 19 – 22).
