Actinopus cucutaensis Mello-Leitão, 1941: 114 View in CoL , fig. 1 (holotype ♂, Cucutá , Norte de Santander, Colombia, ICN, burned); World Spider Catalog, 2020.

Diagnosis. Males of Actinopus cucutaensis differ from all other species of the genus by the apical tegular process nearly 3/4 the size of the embolus. They differ from those of those of A. lomalinda ( Fig. 186 View FIGURE 186 A–C) by the ATP angle of insertion on tegulum and in the presence of a bigger serrated area, which occupies 40% of the embolus, as seen on dorsal view ( Fig. 176 View FIGURE 176 A–C). Females differ from those of all other species of the genus by the two mushroomshaped receptacles, with wide, rounded apexs, and by ca. 90% of receptacles surfaces covered with pores ( Fig. 176 D View FIGURE 176 ).

MALE (INPA 3513): Total length 16.62; Carapace, long 7.37; wide 8.Carapace anterior part tapering.Anterior eye row slightly procurved, posterior row recurved ( Fig. 172 B View FIGURE 172 ). Two bristles between AME-clypeus. Sternum with eight sigilla fused medially, two distal sigilla more fused to each other than others ( Fig. 172 C View FIGURE 172 ). Rastellum protuberant, inverted V-shaped, hirsute, without spines ( Fig. 172 View FIGURE 172 E–F). Chelicerae with 15 denticles along prolateral row of teeth. Prolateral row with six megateeth and one denticle on basal part. Retrolateral row with five megateeth and four denticles between three basal megateeth ( Fig. 172 D View FIGURE 172 ). Patella and tibia III with distal crown of well-developed thorns, interrupted in middle on patella III and not interruped in the middle on tibia III ( Fig. 173 View FIGURE 173 A–B). Patellae III and IV with spines on prolaterodorsal face ( Fig. 173 A, C View FIGURE 173 ). Patella IV with prolaterodorsal short spines along extension of article ( Fig. 173 D View FIGURE 173 ). Ventral pseudoscopulae occupying 30% of tarsi I, 50% of II and 100% of III and IV. Pseudoscopula of tarsi I and II with setae spaced, forming diffuse group of bristles; In tarsi III and IV, compat.
