Diagnosis. Males of Otiothops besotes  sp. n. resemble those of O. brevis Simon, 1893  by size of the palpal tibia, which is wider than the bulb ( Figs 2–4View FIGURES 1–5; see also Platnick 1975, figs 61–62), but can be distinguished by the globeshaped tibia and straight embolus ( Figs 2–4View FIGURES 1–5). The female internal genitalia ( Fig. 5View FIGURES 1–5) resemble those of O. birabeni Mello-Leitão, 1945  by the presence of latero-median poreplates ( Fig. 5View FIGURES 1–5; see also Brescovit and Bonaldo 1993, fig. 4), but differ by the wider anterior portion of the median receptacles, and by the shorter poreplates with a ringed texture.
