Material examined. 2♀ 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 col . ( LEUC; OARA – 089).

Diagnosis. According to Peckham & Peckham (1885) and Galiano (1984), the female of R. geniculata Peckham & Peckham, 1885 is easily distinguishable from other Rudra species, by the appearance of the epigyne with two holes and spermatheca with spiral ducts, at least in part.

Short description. The females collected in the urban area of Montería ( Colombia) are very similar to the description made by Galiano (1984): medium-sized or smaller spiders ( Figures 1‒2 ); slightly marked thoracic stria, located well behind the posterior lateral eyes ( Figure 1 ); female chelicerae, short, vertical, retromargin with an obliquely cut or bi-indented hull; sternum truncated forward, equal to or wider than the base of the lip ( Figure 1 ). Legs: first pair of legs much longer and thicker than the others; all femora with thin spines, sometimes replaced by setae; tibia I and metatarsus I with very thick and long spines, implanted on articular tubers ( Figure 2 ). Legs II, III and IV thin, with few spines ( Figure 2 ). CO with openings to the sides ( Figure 3 ); with spiral ducts, at least in part ( Figures 3‒4 ). Spines (specimens from Colombia): Leg I: F= d 1-1-1; v r0-1-1; T= p 0-0-0; v 2-2-2; M= p 0-0-0; v 2-2; Leg II: F= d 1-1-1; v r 0-1-1; T= p 0-0-0; v 2-2-2; M= p 0-0-0; v 2-2; Leg III: F= d 1-1-1; v= 0-1-1; T= p 0-0-0; v ap 1-0-0; M= p 1ap-r1-0; v 0-0-0; Leg IV: F= d 1-1-1; v 0-0-0; T= 0; M=0.

Measurements (mm; specimens from Colombia). Two females: TL= 4.12-4.53; CH= 1.34; CL= 1.91- 1.93; CW=1.29-1.31; AL= 2.52-2.58; AERW=1.17-1.19; PERW=1.18-1.19; LOQ= 0.62–0.64; PMEP= 0.22– 0.25; eyes of the second row separated from the ALE by 0.14-0.16 mm and from the PLE by 0.15-0.16 mm.

Distribution. Rudra geniculata Peckham & Peckham, 1885 was previously known only from Guatemala and Panama in Central America ( Metzner, 2020; WSC, 2020). This is the first record of this genus and species from Colombia, and from the northern hemisphere of South America ( Figure 5 ). The specimen from Colombia was collected by shaking foliage of the introduced Mango tree, Mangifera indica L., in an urban perimeter during daylight hours.
