Etymology. The specific name refers to musician and multi-instrumentalist Michael Trent Reznor, founder of industrial music, leader of the Nine Inch Nails and affiliated to many other bands, in addition to his producer career.

Diagnosis. Males of Actinopus reznori   differ from those of A. anselmoi   ( Fig. 171 View FIGURE 171 A–C) by the more conspicuous PA; two keels visible on prolateral copulatory bulb and serrated area dorsally located on prolateral embolus ( Fig. 168 View FIGURE 168 A–C).

MALE (IBSP 9992): Total length 7.4; Carapace, long 3.9; wide 3.5. Carapace rounded. Anterior eye row slightly procurved, posterior row recurved ( Fig. 166 B View FIGURE 166 ). With few 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. 166 C View FIGURE 166 ). Rastellum protuberant, digitiform, hirsute, with a row of short spines apically ( Fig. 166 View FIGURE 166 E–F). Chelicerae with ten denticles along prolateral row of teeth. Prolateral row with five megateeth and one basal tooth. Retrolateral row with six megateeth and three denticles along three basal megateeth ( Fig. 166 D View FIGURE 166 ). Patella and tibia III with distal crown of well-developed thorns, not interrupted in middle ( Fig. 167 View FIGURE 167 A–B). Patellae III and IV with spines on prolaterodorsal surface ( Fig. 167 A, C View FIGURE 167 ). Tibia IV without spines on dorsal surface ( Fig. 167 D View FIGURE 167 ). Ventral pseudoscopulae occupying 50% of tarsus I, 70% of II, 10% of metatarsi III 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; tibia of palp yellow; Abdomen pale gray ( Fig. 166 A View FIGURE 166 ). Eyes: Diameters: PME 0.18, PLE 0.28, ALE 0.34, AME 0.15; MOQ: Length 0.84, front width 2.18, back width 1.96; Interdistances: PME–PME 1.09, PLE–PME 0.09, AME–AME 0.18, ALE–AME 0.62, ALE–PLE 0.34, AME–PME 0.40.

Palp: PA small but conspicuous. Embolus with two keels (PI and PS). BTA developed, displaced dorsally in relation to a middle longitudinal line along prolateral tegular surface; serrated area represented by cusps dorsally located in prolateral view of embolus; PA continuous to PI; Embolar base thin ( Fig. 168 View FIGURE 168 A–C).
