Colonus pseustes ( Chamberlin & Ivie, 1936) : Chamberlin & Ivie, 1936; Maddison & Ruiz, 2015; Bustamante et al. 2015; Carvalho & Gasnier, 2019. Type material deposited in the AMNH, not examined.

Material examined. 3♂, Colombia, Córdoba, Montería [8°47'25.6"N, 75°51'42.4"W], [2m] 22 Apr 2018, 3 Oct 2018, urban area, Mangifera indica L . tree, shaking foliage, E. Bedoya – Roqueme coll . ( LEUC; OARA – 089).

Diagnosis. According to Chamberlin & Ivie (1936) and Bustamante et al. (2015) the male of C. pseustes is easily distinguishable from other Colonus species by the embolus ( Figures 4-5 , 9 ), and the form of the RTAs, with the dorsal RTA shorter or almost as long as ventral RTA, which gradually decreases distally and ends in a sharp tip ( Figures 6-8 , 10-11 ).

Descriptions of specimens. According to Chamberlin & Ivie (1936), cephalothorax reddish-brown; clypeus dark, with a line of white hair; all legs dark brown, light yellow femur, at least in part ( Figures 1- 2 ). Large white hair spot in the eye quadrangle, at the level of the PLE ( Figure 3 ); three lines of semicircular white hairs close to the PLE; ocular quadrangle bordered by a series of reddish brown hairs ( Figure 3 ); according to Chamberlin & Ivie (1936) there are two lines of white hair in decline on the posterior part of the cephalothorax ( Figure 3 ). Chelicerae reddish, covered in shiny black on the front, with one tooth on the retrolateral margin, and four small teeth of the same size on the prolateral margin. Sternum longer than wide, with anterior end of same width as base of the labium ( Figure 2 ). Abdomen long, with two lines of white hairs in dorsal view ( Figure 1 ), and with a dark brown region in ventral view, with small lighter points inside, which follow two parallel lines ( Figure 2 ).

The figures of the pedipalps provided by Chamberlin & Ivie (1936), are sufficiently detailed, which allow an exact comparison with the specimens from Colombia (see Chamberlin & Ivie, 1936; Fig. 141-142). Tibia of each palp with two RTAs ( Figures 4–8 ), both directed on the prolateral margin ( Figures 9-11 ), one sclerotic with a marked curvature in the subapical position and ending in a sharp tip, the other is spiniform ( Figure 11 ). The bulb is large and elongated ( Figures 4-5 ), spermatic ducts sinuous, visible and thickness ( Figures 9-10 ). In the specimen from Colombia, embolus long and thinner from the base ( Figures 4-5 ), slightly curved, where it occupies a protective depression ( Figure 9 ). Femur curved, with a small spine in a sub-apical position. Short legs, the first two pairs slightly more robust than the later ones; the first femur is somewhat claviform, and the other leg segments are cylindrical. Spines (Specimen from Colombia): Leg I: F=d 0-0-1-2-2(1pd), v01-1r-0; T=p 0-0-0, vr0-2-2; M=p 0-0-0, v r0-2-2. Leg II: F=d 0-0- 1-2-2(1pd), v01-1r-0; T=p 1-0-r1, v0-2-2, r0-1-1; M=p 0-0-0, v r0-2-2. Leg III: F=d 0-1-1 (1p) (1r), p 0-1-1, r 0-1-1; T= d1-0-0, v2-0-2, p2-2-2di; M=p0-0-0, v2-0-0. Leg IV: F=d 1-1-1 (1p) (1r), p 0-1-1, r 0-1-1; T= d1-0-0, v2-0-2, p2-2-2di; M=p 0-1d-0, v2-0-0.

Measurements (mm; specimens from Colombia). Three males: TL= 7.5-8.3; CL= 3.22-3.54; CW= 2.16- 2.94; AL= 4.66-4.74; AERW= 2.09-2.15; PERW= 2.23-2.35; LOQ= 1.41-1.43; PMEP= 0.26-0.29; eyes of the second row separated from the ALE by 0.40-0.42 mm and from the PLE by 1.34-1.36 mm.

Distribution. Brazil, Colombia *, French Guiana, Panamá ( Figure 15 ) ( Metzner, 2020; WSC, 2020).
