Actinopus wallacei F. O. Pickard-Cambridge, 1896: 728, pl. 35, fig. 18 31 (holotype ♀, Santarém, Pará, Brazil, NHM, examined); Schiapelli & Gerschman, 1945: 167, pl. I; World Spider Catalog, 2020.
Note. The types were not available for study and for this reason the male is not redescribed here. The females here ascribed to A. wallacei are from Bolivia but present diagnostic characters congruent with the female type, examined through images by Janet Beccaloni (Figs 223– 224).
Diagnosis. Females of Actinopus wallacei differ from all other species represented by females by the reddish-brow pattern widespread on legs, Chelicerae and carapace without larger tone differences. They are similar to those of A. pampulha by the spermathecae shape: two receptacles, each one with 2 or 3 lobes with same height as each other. They differ from those of A. pampulha by the pore distribution reaching reaches 75% of the apical area in each receptacle.
FEMALE (AMNH): Total length 19.12; Carapace, long 6.75; wide 6.87. Carapace anterior part square. Anterior eye row slightly procurved, posterior row recurved. Short and long bristles in three rows between AME-clypeus, one long bristle between PLE–ALE, short and long bristles between posterior eyes-fovea and short and long bristles between lateral eyes-edge of carapace (Fig. 221 B). Sternum with eight sigilla fused medially, all sigilla very fused to each other (Fig. 221 C). Rastellum protuberant, subquadrate, hirsute, with a row of spines on the edge of rastellum and o lot of spines in dorsal part of rastellum (Fig. 221 E–F). Chelicerae with denticles along prolateral row of teeth. Prolateral row with eight megateeth and one tooth after the last basal megateeth. Retrolateral row with five megateeth and two teeth between three medial megateeth (Fig. 221 D). Patella and tibia III with distal developed crowns of thorns (Fig. 222 A–B). Patella IV with prolaterodorsal spines along extension of article (Fig. 222 C). Tibia IV without spines and with many short and long bristles on surface of article (Fig. 222 D). Carapace, chelicerae, sternum, coxae, trochantera, femora, patellae, Tibia, metatarsi, tarsi and palp reddish brown, and abdomen pale gray (Fig. 221 A). 12 labial cuspules, 105 on right maxilla and 99 on left.
