Diagnosis. Males of Actinopus clavero are unique in Actinopus by the shape of the copulatory bulb, with embolus elongated and winding along longitudinal line of tegulum, resembling in that regard the shape of the copulatory bulb in Missulena . ( Fig. 209 View FIGURE 209 A–C); they also present the dorsal surface of ocular area and chelicerae slightly granulated ( Fig. 207 B View FIGURE 207 ) and three spines on basal third on dorsal surface of tibia III ( Fig. 208 C View FIGURE 208 ). Females are unique in Actinopus by the shape of receptacles, very elongated and with a tapered apex.

MALE (MACN-Ar 19827): Total length 12.25; Carapace, long 5.37; wide 5. Carapace rounded. Anterior eye row slightly procurved, posterior row slightly recurved ( Fig. 207 B View FIGURE 207 ). With short and weak bristles between AMEclypeus, betweenALE–ALP,between posterior eyes-fovea and lateral eyes-edge of carapace. Sternum with eight sigilla converging to the middle but separeted ( Fig. 207 C View FIGURE 207 ). Rastellum protuberant, digitiform, hirsute, with many short spines covering apex ( Fig. 207 View FIGURE 207 E–F). Chelicerae with twelve denticles along prolateral row of teeth. Prolateral row with six megateeth. Retrolateral row with five megateeth and one tooth between two basal megateeth ( Fig. 207 D View FIGURE 207 ). Patella and tibia III with distal crown of well-developed thorns, not interrupted in middle ( Fig. 208 View FIGURE 208 A–B). Patellae III and IV with spines on prolaterodorsal face ( Fig. 208 A, C View FIGURE 208 ). Tibia IV without spines on dorsal surface ( Fig. 208 D View FIGURE 208 ). Ventral pseudoscopulae occupying 50% of tarsus I, 70% of II, 20% of metatarsi IV and 100% of III and IV. Pseudoscopula of tarsi I, II and metatarsi IV 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; Abdomen pale brown with a scutum covering 1/3 of anterior dorsal surface o abdomen ( Fig. 207 A View FIGURE 207 ).
