Differential diagnosis
Females of A. noctua sp. nov. are differentiated from those of all species of the pectorosa and pacifica groups by the following features: atrium small, lateral borders sinuous, hood triangular, posteriorly curved at the center, genital openings at the posterior margin of the atrium, copulatory ducts short, comma-shaped (Figs 37E–F, 38C–D).
Etymology
The species epithet is derived from the Latin ‘ noctua ’ (‘owl’), in reference to the characteristic shape of the epigynum and atrium that are reminiscent of a horned owl with the spermathecae as its eyes.
