Diagnosis.

The male differs from those of Fufius funebris by the shorter and tapering embolus (see figs 8-10 in Guadanucci and Indicatti 2004), from Fufius jalapensis sp. n. by having spines on tibia I, from Fufius minusculus sp. n. by having a carapace less than 1.5 times longer than the width, from Fufius albovittatus by metatarsus I being very curved at the basis and having only 2 spines on tibia I, from Fufius candango sp. n. by the preening comb on metatarsus IV formed by macrosetae instead of small spines, and from Fufius striatipes by having only 2 spines on tibia I instead of 11. The female differs by the spermatheca stalk being straight and narrow, and giving origin to 1-2 lobes (Fig. 14).
