Goloboff leg., MACN-Ar 36533); World Spider Catalog, 2020 . 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 A–C); they also present the dorsal surface of ocular area and chelicerae slightly granulated ( Fig. 207 B ) and three spines on basal third on dorsal surface of tibia III ( Fig. 208 C ). 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 ). 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 ). Rastellum protuberant, digitiform, hirsute, with many short spines covering apex ( Fig. 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 ). Patella and tibia III with distal crown of well-developed thorns, not interrupted in middle ( Fig. 208 A–B). Patellae III and IV with spines on prolaterodorsal face ( Fig. 208 A, C ). Tibia IV without spines on dorsal surface ( Fig. 208 D ). 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 ).
