Variation. Hind femur entirely black, except ventral basal half dark reddish; hind femur yellow at base and ventrally, slowly becoming black towards apex;

Taxonomic discussion. This species can be differentiated from other Catostola species by the absence of femoral swelling with short, stout macrosetae on hind femora and by the colour of legs mostly yellow ( Fig. 9A View FIGURE 9 ). The most similar species are Catostola martini ( Fisher, 1992) comb. nov., Catostola indecisa sp. nov., and Catostola complicata ( James, 1953) comb. nov. It can be distinguished from the two first by the yellow colour of the hind femur with only the apex and an anterior band dark brown to black fading proximally ( Fig. 9A View FIGURE 9 ) and from the last one by the shape of the epandrial finger-like projection that becomes constricted only sub-apically ( Fig. 11E View FIGURE 11 ) and the gonocoxite apex that also only becomes constricted sub-apically ( Fig. 12E View FIGURE 12 ).

Distribution ( Fig. 44 View FIGURE 44 ). Colombia (new record) (La Guajira, Magdalena, Cesar and Tolima) and Venezuela (Vargas, Aragua, Miranda, Carabobo and Guárico) ( Vieira et al. 2017).
