Etymology. The name is a patronym in honour of our friend and colleague, the arachnologist from the Museu Nacional, Rio de Janeiro, Adriano Brilhante Kury, nicknamed “Adrik”.

Diagnosis. Males of Falconina adriki sp. nov. resemble those of F. crassipalpis sp. nov. by the RTA composed of only two lobes, the dorsal one being absent, and by the laminar, sculptured tegular process. They differ by the absence of a dorsal process on the ventral lobe of the RTA and by the sub-squared tegular process, without a basal membranous sector ( Figs 15A–B View FIGURE 15 , 16A–B View FIGURE 16 ). Females differ from those of other Falconina species with the posterior margin of the epigynal plate without a pronounced median notch by the posterior margin of the epigynal plate abruptly curved laterally and by the posterior vulvar plate as long as wide ( Figs 15C–D View FIGURE 15 , 16C–D View FIGURE 16 ).

Male palp. Tibia almost half of cymbium length. Two lobes. Ventral lobe with long, thin apical spur, smaller than median lobe ( Figs 15A View FIGURE 15 , 16A View FIGURE 16 ). Median lobe well-developed, with concave prolateral surface, sub-rectangular. Dorsal lobe absent. Cymbium with well-developed, sub-squared retrolateral basal process. Basal prolateral process present. Spermophore with five ventral folds. Tegular process sub-rectangular, with apex rounded and striated, tegular depression at base of tegular process absent.
