Diagnosis. The male of Dipoena fozdoiguacuensis new species resembles that of D. tiro Levi, 1963 (see Levi, 1963: 171, fig. 227) in the median apophysis with a projection (Fig. 23) and in the pattern and shape of the carapace in lateral view (Fig. 25), but differs in the projection in D. fozdoiguacuensis more ventrally positioned and the larger embolus (Fig. 23). The female of Dipoena fozdoiguacuensis is close to D. tiro Levi, 1963 (see Levi, 1963: 171, fig. 225, 226), but differs from it in the pattern and shape of the epigynum in ventral view, by circular copulatory opening (Fig. 26) and in the circular first spermathecae (Fig. 27).
