Etymology. The specific name refers to the type locality, Floresta Nacional do Jamarí, Porto Velho, Rondônia, Brazil.

Diagnosis. Males of Actinopus jamari resemble those of A. tarsalis ( Fig. 9 View FIGURE 9 A–C), A. castelo ( Fig. 12 View FIGURE 12 A–C) and A. concinnus ( Fig. 195 View FIGURE 195 A–C) by the absence of BTA, but are readily recognized by the large PA with a keel inserted apically on bulb, flattened and apically folded, oblique in relation to embolus ( Fig. 198 View FIGURE 198 A–C).

MALE (IBSP): Total length 20.25; Carapace, long 11.5; wide 10.87. Carapace anterior part tapering and posterior part triangular. Anterior eye row slightly procurved, posterior row recurved ( Fig. 196 B View FIGURE 196 ). With few short 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. 196C View FIGURE 196 ). Rastellum protuberant, inverted V-shaped, hirsute, without spines apically ( Fig. 196 View FIGURE 196 E–F). Chelicerae with 15 denticles along prolateral row of teeth. Prolateral row with five megateeth and two basal tooth. Retrolateral row with five megateeth, two basal teeth between three basal megateeth and three denticles along two basal megateeth ( Fig. 196 D View FIGURE 196 ). Patella and tibia III with distal crown of well-developed thorns, not interrupted in middle ( Fig. 197 View FIGURE 197 A–B). Patellae III and IV with spines on prolaterodorsal face ( Fig. 197 A, C View FIGURE 197 ). Tibia IV without spines on dorsal surface ( Fig. 197 D View FIGURE 197 ). Ventral pseudoscopulae occupying 30% 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 reddish-dark-brown; Abdomen pale gray with small orange spots of unpigmentation on dorsal surface ( Fig. 196 A View FIGURE 196 ).

Palp: PA conspicuous, displaced dorsally in relation to middle longitudinal line along prolateral tegular surface and away from tegular border. Embolus with two keels (PI and PS). BTA developed and displaced dorsally in relation to a middle longitudinal line along prolateral tegular surface; serrated area with three rows of big notable cusps below PA in prolateral view; PA continuous to PS; Embolar base flattened, PI rotating the length of embolus from base to apex; several grooves covering prolateral tegular surface ( Fig. 198 View FIGURE 198 A–C).
