Etymology. The specific name is a composed Latin noun and refers to the paraembolic apophysis, which is very pronounced in this species.

Diagnosis. Males of Actinopus parafundulus differ from A. urucui ( Fig. 165 View FIGURE 165 A–C) by the longer tegulum; presence of only two keels (PS and PI) on copulatory bulb; and by the largest PA found in Actinopus , extending the tegular lateral edge ( Fig. 162 View FIGURE 162 A–C).

MALE (MPEG 2242): Total length 10.5; Carapace, long 5.7; wide 5.8. Carapace anterior part tapering. Anterior eye row slightly procurved, posterior row recurved ( Fig. 160 B View FIGURE 160 ). With five short and 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. 160 C View FIGURE 160 ). Rastellum protuberant, inverted V-shaped, hirsute, with one spine apically ( Fig. 160 View FIGURE 160 E–F). Chelicerae with seven denticles along prolateral row of teeth. Prolateral row with five megateeth and one basal tooth. Retrolateral row with five megateeth and one denticle between the thirty distal and forty basal megateeth ( Fig. 160 D View FIGURE 160 ). Patella and tibia III with distal crown of well-developed thorns, not interrupted in middle ( Fig. 161 View FIGURE 161 A–B). Patellae III and IV with spines on prolaterodorsal face ( Fig. 161 A, C View FIGURE 161 ). Tibia IV without spines on dorsal surface ( Fig. 161 D View FIGURE 161 ). Ventral pseudoscopulae occupying 50% of tarsus I, 70% 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 yellowish brown; Abdomen pale brown ( Fig. 160 A View FIGURE 160 ).
