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 View Fig ), and from A. epicardia sp. nov. by the middle coil of the copulatory ducts ( Fig. 27G–H View Fig ). 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 View Fig , 27A View Fig (arrows)), the more elongated and curved median apophysis hook ( Figs 26A View Fig , 27A View Fig ), the RTA posterior branch being hook-shaped ( Figs 26D View Fig , 27D View Fig ) and the large spurs of coxa II–IV ( Figs 25F View Fig , 27E–F View Fig ).

Etymology

The species epithet is dedicated to Dulce Flor Piedra-Jiménez, Mexican arachnologist, and former member of the second author’s lab.
