Differential diagnosis
Females of A. ibarrai sp. nov. can be differentiated from those of A. porta sp. nov. and A. salgueiroi sp. nov. by the genital openings being shaped as two large sclerotized chambers, copulatory ducts also well sclerotized, and the atrium lateral borders diverging posteriorly ( Figs 43E–F View Fig , 44C–D View Fig ).
Etymology
The species epithet is dedicated to the Mexican arachnologist Dr Guillermo Ibarra.
