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, 18E–F). The female of A. rebecae sp. nov. also has a similar trapezoidal atrium, and copulatory duct paths (Fig. 28E–F), 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).
Etymology
The species epithet is dedicated to Francisco Rivera, father of the first author.

Abdomen dorsal surface white and delineated by two light brown parallel longitudinal lines, lateral surfaces white and dorsally delineated by light brown longitudinal lines, ventral surface center with faint light brown longitudinal band from epigastric furrow to spinneret bases, tracheal spiracle closer to epigastric furrow (Fig. 17A–C). Anterior area of epigynal plate delineated laterally by two faint triangular pits. Genital openings at both sides of anterior edge of atrium under hood. Copulatory duct slightly curved and entering surface of anterior spermathecae. Seminal receptacles oval in anterior third of copulatory ducts.
