The male of Typhochlaena chapadensis sp. nov. resembles those of T. curumim by having a long embolus, between two and three times the tegulum length (Figs 10, 12–15) and the abdomen pattern black with 4 lateral reddish spots (Figs 1, 2, 6). It can be distinguished from those of T. curumim by the slender embolus, narrowing abruptly from the tegulum (Figs 12–14) and the more conspicuous whitish rings on the distal patellae, tibiae and metatarsi (Fig. 1), as well as the dark cephalic area and abdomen dorsum with numerous long and whitish setae (Figs 1–4, 6).
