Dipoena bonitensis new species

( 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. 19 ), but differs in the larger projection of D. bonitensis ( Fig. 19 ). 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. 22 ), but differs from it in the wider copulatory opening ( Fig. 22 ).
