Etymology. The specific name refers to musician Philip Hansen Anselmo, or Phil Anselmo, the main singer of Pantera, one of the most respected trash metal bands of the world.

Diagnosis. Males of Actinopus anselmoi differ from those of A. reznori ( Fig. 168 View FIGURE 168 A–C) by the inconspicuous PA; presence of only one keel on prolateral copulatory bulb and serrated area ventrally located on prolateral embolus ( Fig. 171 View FIGURE 171 A–C).

MALE (IBSP 114469): Total length 8; Carapace, long 4.25; wide 4.08. Carapace anterior part tapering. Anterior eye row slightly procurved, posterior row recurved ( Fig. 169 B View FIGURE 169 ). With many 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. 169 C View FIGURE 169 ). Rastellum protuberant, digitiform, hirsute, with strong spines apically ( Fig. 169 View FIGURE 169 E–F). Chelicerae with seven denticles along prolateral row of teeth. Prolateral row with five megateeth. Retrolateral row with six megateeth and three denticles along two basal megateeth ( Fig. 169 D View FIGURE 169 ). Patella and tibia III with distal crown of well-developed thorns, not interrupted in middle ( Fig. 170 View FIGURE 170 A–B). Patellae III and IV with spines on prolaterodorsal face ( Fig. 170 A, C View FIGURE 170 ). Tibia IV without spines on dorsal surface and with two visible of trichobothria ( Fig. 170 D View FIGURE 170 ). 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 reddish brown; tibia of palp yellowish, paler than other articles. Abdomen pale gray ( Fig. 169 A View FIGURE 169 ).
