Diagnosis

Males of Tafana ruizi sp. nov. resemble those of T. straminea and T. kunturmarqa sp. nov. by having the base of the embolus large and inclined, but differ by having the ventral tegular process large and apex of tegulum not rounded ( Fig. 21C View Fig ). Females resemble those of T. straminea and T. kunturmarqa sp. nov. by having the atrial septum, but differ by having the wide atrium, showing the copulation openings and hood long and circular ( Figs 21F–G View Fig , 33B View Fig ).

Etymology

The specific name is a patronym in honor of the Cuban arachnologist Alexandre Sánchez-Ruiz for his contributions to the taxonomy of spiders.
