Differential diagnosis

The female of A. franciscoi sp. nov. is differentiated from all those of species of the pectorosa and pacifica groups by the following features: atrium trapezoidal, hood broad and posteriorly curved at the center ( Figs 17E–F View Fig , 18E–F View Fig ). The female of A. rebecae sp. nov. also has a similar trapezoidal atrium, and copulatory duct paths ( Fig. 28E–F View Fig ), but it differs from that of A. franciscoi sp. nov. by the notched hood and smaller size (7.23 ±1.1). Anyphaena sofiae sp. nov. shares similar copulatory duct paths and spermathecal proportions with both species, but differs by the oval atrium and copulatory ducts extending beyond the hood ( Fig. 36E–F View Fig ).

Etymology

The species epithet is dedicated to Francisco Rivera, father of the first author.
