Type material. Holotype male from [10º 47’ 27.33” S 65º 19’ 55.98” W], Guajará-Mirim , Rondônia, Brazil, i.2001, M. Carvalho leg. ( IBSP 114463 View Materials ) .

Diagnosis. Males of Actinopus guajara are similar to those of A. cucutaensis ( Fig. 176 View FIGURE 176 A–C) and A. lomalinda ( Fig. 186 View FIGURE 186 A–C) by the ATP parallel to the embolus in prolateral view. They differ from those of both these species by the longer tegulum, and by the slender, less robust ATP ( Fig. 192 View FIGURE 192 A–C).

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

MALE (Holotype): Total length 7.9; Carapace , long 4; wide 3.7. Carapace anterior part rounded. Eyes.Anterior eye slightly procurved, posterior row recurved ( Fig. 190 B View FIGURE 190 ). With four bristles between AME-clypeus. One long bristle between ALE–ALP and 14 short and weak bristles between PE-fovea. Sternum with eight sigilla fused medially, two distal sigilla more fused than others ( Fig. 190 C View FIGURE 190 ). Rastellum protuberant, inverted V-shaped, hirsute, with strong widespread spines apically ( Fig. 192 View FIGURE 192 D–E). Chelicerae with four denticles along Prolateral row and one denticle along retrolateral row of teeth. Prolateral row with five megateeth. Retrolateral row with six megateeth ( Fig. 190 D View FIGURE 190 ). Patella and tibia III with distal crown of well-developed thorns, interrupted in middle on patella III and not interrupted in middle on tibia III ( Fig. 191 View FIGURE 191 A–B). Patellae III and IV with spines on prolaterodorsal face ( Fig. 191 A, C View FIGURE 191 ). Tibia IV without spines on prolateral surface ( Fig. 191 D View FIGURE 191 ). Ventral pseudoscopulae occupying 20% 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, metatarsi and tarsi pale brown; Abdomen pale gray ( Fig. 190 A View FIGURE 190 ).

Palp: poorly developed PA poorly developed, embolus without prolateral keels. Basal surface of tegulum smooth ; BTA small but visible in prolateral and retrolateral views, displaced ventrally on prolateral tegular surface; prolateral embolus with denticles along base. ATP nearly 75% of embolus length; embolar base thin ( Fig. 192 View FIGURE 192 A–C).
