Etymology. The specific name is a noun in apposition from the type locality name.

Diagnosis. Males of Actinopus urucui differ from A. parafundulus ( Fig. 162 A–C) by the leg metatarsi and tarsi paler than other articles; shorter tegulum; presence of three keels (PAc, PS and PI) on copulatory bulb; and a smaller PA ( Fig. 165 A–C).

MALE (MPEG 13206): Total length 9.38; Carapace, long 4.63; wide 3.88. Carapace rounded. Anterior eye row slightly procurved, posterior row recurved ( Fig. 163 B ). With short an weak bristles between AME-clypeus, between ALE–ALP, between posterior eyes-fovea and lateral eyes-edge of carapace. Sternum with eight sigilla fused medially, two distal sigilla more fused than others ( Fig. 163 C ). Rastellum protuberant, inverted V-shaped, hirsute, without spines apically ( Fig. 163 E–F). Chelicerae with eight denticles along prolateral row of teeth. Prolateral row with four megateeth and one basal tooth. Retrolateral row with six megateeth ( Fig. 163 D ). Patella and tibia III with distal crown of well-developed thorns, on patella III interrupted in middle and on tibia III not interrupted in middle ( Fig. 164 A–B). Patellae III and IV with spines on prolaterodorsal face ( Fig. 164 A, C ). Tibia IV without spines on dorsal surface ( Fig. 164 D ). Ventral pseudoscopulae occupying 10% of tarsus I, 40% of II and 100% of III and IV. Pseudoscopula of tarsi I and II with setae spaced, forming diffuse group of bristles; On tarsi III and IV, compact. Carapace, chelicerae, sternum, coxae, trochantera, femora, patellae, tibiae pale brown; metatarsi and tarsi of legs yellowish brown, paler than other articles; Abdomen pale gray ( Fig. 163 A ).
