Etymology. The species epithet is in honor of Dr. Eduardo Flórez Daza (Universidad Nacional de Colombia) for his enormous contributions to Colombian arachnology. The name is a noun in genitive.

Diagnosis. Males of G. florezi  resemble those of G. lacteovittata  by the distal prolaterally oriented fold of the conductor lamina ( Figs. 16BView FIGURE 16, 18 AView FIGURE 18). They are distinguished from the latter by the absence of filiform projections in the distal portion of the embolus ( Figs. 16DView FIGURE 16, 18 A –EView FIGURE 18). Females resemble those of G. lacteovittata  and G. boraceia  by the median projection of the uterus externus ( Figs. 17 A –EView FIGURE 17); distinguished from the former by the presence of one posterior cheliceral bulge ( Fig. 15FView FIGURE 15) and from the latter by the position of the posterior bulge, which is located at the level of Ret3 and Ret4 as seen in mesal view ( Fig. 15FView FIGURE 15).

Male (holotype). Habitus as in Figures 14 A –DView FIGURE 14. Carapace pale brown, darker along sides and median region. Sternum dusky brown. Abdomen oval, dorsally with irregular pattern of two longitudinal black bands that join medially forming thin transverse bands in the posterior region. Silver guanine spots scattered in dorsal and lateral surfaces. Venter with a dusky median band that ramifies towards the lateral surface into thin irregular bands. Legs light yellow-brownish with distal parts of segments darker. Tracheal spiracle well-sclerotized. Total length 3.90. Cephalothorax 1.62 long, 1.27 wide, 1.07 high. Abdomen 2.35 long, 1.87 wide, 1.75 high. Sternum 0.72 long, 0.82 wide. Eye diameters and interdistances: AME 0.11. ALE 0.09. PME 0.11. PLE 0.08. AME-AME 0.08, AME-ALE 0.07, PME-PME 0.10, PME-PLE 0.14, ALE-PLE 0.01. Clypeus height 2.40. Chelicerae with the same coloration of the cephalothorax. Three promarginal and four retromarginal teeth.

Paracymbium with short distal portion ( Figs. 16HView FIGURE 16, 18DView FIGURE 18). Conductor lamina with a distal prolaterally oriented fold ( Figs. 16BView FIGURE 16, 18 AView FIGURE 18). Embolus with tooth-like projections ( Fig. 16DView FIGURE 16). Medial groove limited to the inner surface ( Fig. 18BView FIGURE 18).

Female (paratype ICN 5977). Coloration and general habitus as in male ( Figs. 14E –HView FIGURE 14). Abdomen with three longitudinal black bands, one median bifurcated at the anterior region and two laterals. Total length 3.85. Cephalothorax 1.60 long, 1.30 wide, 0.80 high. Abdomen 2.65 long, 2.00 wide, 1.75 high. Sternum 0.80 long, 0.82 wide. Eye diameters and interdistances: AME 0.10. ALE 0.08. PME 0.11. PLE 0.08.
