Etymology. The specific name is in honor of musician Ronald James Padavona or Ronnie James Dio, one of Black Sabbath vocals, affiliated to several bands of heavy metal in addition to his solo career.
Diagnosis. Males of A. dioi differ from those of A. osbournei ( Fig. 135 View FIGURE 135 A–C) by the palpal tibia paler than other articles; PA inconspicuous; tegulum longer; cusps of serrated area present along length of embolus; embolus flattened ( Fig. 138 View FIGURE 138 A–C).
MALE (MPEG): Total length 9.5; Carapace, long 4.58; wide 4.66. Carapace anterior part tapering. Anterior eye row slightly procurved, posterior row recurved ( Fig. 136 B View FIGURE 136 ). With one long bristle and many short/weak bristles forming a row on the border of clypeus. With few, short and weak bristles between ALE–ALP, between posterior eyes-fovea and lateral eyes-edge of carapace. Sternum with eight sigilla converging to the middle, but separated, two basal sigilla bigger and more fused than others ( Fig. 136 C View FIGURE 136 ). Rastellum protuberant, digitiform, hirsute, without spines apically ( Fig. 136 View FIGURE 136 E–F). Chelicerae with 12 denticles along prolateral row of teeth. Prolateral row with five megateeth and two teeth on basal portion. Retrolateral row with seven megateeth ( Fig. 136 D View FIGURE 136 ). Patella and tibia III with distal crown of well-developed thorns, on patella III interrupted in middle and on tibia III not interrupted in middle ( Fig. 137 View FIGURE 137 A–B). Patellae III and IV with spines on prolaterodorsal face ( Fig. 137 A, C View FIGURE 137 ). Tibia IV without spines on dorsal surface and two rows of filiform trichobothria on dorsal surface ( Fig. 137 D View FIGURE 137 ). 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 and tibiae dark brown; Metatarsi and tarsi dark brown, paler than other articles; Abdomen gray ( Fig. 136A View FIGURE 136 ). Eyes: Diameters: PME 0.25, PLE 0.34, ALE 0.41, AME 0.31; MOQ: Length 0.87, front width 2.62, back width 2.31; Interdistances: PME–PME 1.41, PLE–PME 0.09, AME–AME 0.16, ALE–AME 0.69, ALE–PLE 0.37, AME–PME 0.41.

Palp: PA developed, embolus with three keels (PAc, PI and PS). BTA developed and placed medially on prolateral tegular surface; serrated area developed, represented by many cusps below PAc in prolateral view; thin and elongated tegulum, thin embolar base. PS reaching the embolar edge on dorsal view ( Fig. 138 View FIGURE 138 A–C).
