Differential diagnosis
Females of Anyphaena dulceae sp. nov. can be differentiated from those of all other species of the pectorosa and pacifica groups by the heart-shaped epigynal atria (Fig. 26E–F), and from A. epicardia sp. nov. by the middle coil of the copulatory ducts (Fig. 27G–H). Males of this species resemble those of A. fraterna (Platnick 1974: figs 52, 56, 60) and A. simoni (Brescovit & Lise 1989: figs 1–9) by their elongated ventral tegular projection with a rounded tip and the hook-shaped median apophysis, but differ from these species by the presence of a rectangular process at the ventral tegular projection base (Figs 26A, 27A (arrows)), the more elongated and curved median apophysis hook (Figs 26A, 27A), the RTA posterior branch being hook-shaped (Figs 26D, 27D) and the large spurs of coxa II–IV (Figs 25F, 27E–F).
Etymology
The species epithet is dedicated to Dulce Flor Piedra-Jiménez, Mexican arachnologist, and former member of the second author’s lab.
