Diagnosis. Males of Fernandezina eduardoi sp. n. resemble those of F. ilheus Platnick, Grismado & Ramírez, 1999 by the distally constricted bulb ( Figs 31–33 ; see also Platnick et al. 1999, figs 22–24), but can be distinguished by the considerably longer, curved embolus, and by the longer narrow neck of the palpal bulb ( Figs 31–33 ). Female can be distinguished from other congeners by the short and curved receptacles ( Fig. 34 ).

Etymology. The specific epithet is a patronym in honour of Dr. Eduardo Florez Daza, a researcher of Colombian arachnids and professor of the Universidad Nacional de Colombia.

Description. Male (holotype, ICN-Ar10685): Total length 2.63. Carapace: reddish-brown; 1.35 long, 1.05 wide (at leg II), 0.57 high (at leg II). Posterior median eyes separated by almost 3.0 x their own diameter. Legs: orange-brown, first legs slightly darker; femur 0.92 long, 0.46 wide. Abdomen: yellowish-brown; 1.18 long; abdominal scute covering ca. 42% of dorsum. Palpal femur not thickened, 2.5 x longer than wide; tibia longer than wide; bulb funnel-shaped, narrowed in the apical quarter; embolus 0.63 long, 2.0 x longer than cymbium, slightly curved with strongly curved tip ( Figs 31–33 ).

Female (paratype, ICN-Ar10686): Total length 2.85. Carapace: reddish brown; 1.40 long, 1.03 wide (at leg II), 0.65 high (at leg II). Posterior median eyes separated by almost 3.0 x their own diameter. Legs: orange-brown, first legs slightly darker; femur 1.24 long, 0.38 wide. Abdomen: yellowish-brown; 1.45 long; scute covering ca. 15% of dorsum. Internal genitalia with two short receptacles, thin and curved at the tip, wider at the base ( Fig. 34 ).

Distribution. Known only from the type locality at Usiacurí, Atlántico, Colombia.

Natural history. The holotype and paratype were found in leaf litter in tropical dry forest.
