Differential diagnosis

Females from Anyphaena epicardia sp. nov. can be differentiated from those of all other American species of the pectorosa and pacifica groups by the heart-shaped atrium of the epigynum ( Fig. 23E–F View Fig ), and from those of A. dulceae sp. nov. by the straight copulatory ducts ( Fig. 24G–H View Fig ). Males of this species resemble those of A. fraterna ( Platnick 1974: figs 52, 56, 60) and A. simoni Becker, 1878 ( Brescovit & Lise 1989: figs 1–9) by their elongated ventral tegular projection, but differ from both species by the presence of an apical translucent curved lamella ( Figs 23A–D View Fig , 24A–D View Fig (arrows)), a broader median apophysis in ventral view ( Figs 23A View Fig , 24A View Fig ), an acute spine on the ventral corner of the trapezoidal RTA posterior branch ( Figs 23D View Fig , 24D View Fig ) and the coxa III tubercle bifurcated ( Figs 22F View Fig , 24E–F View Fig ), this last feature more similar to A. simoni than A. fraterna .

Etymology

The species epithet is a combination from the Spanish words epigino and cardia, referring to the heart-shaped epigynum atrium, a diagnostic feature of this species.

Natural history

Most specimens were collected over vegetation by direct searching or with a beating tray; some male specimens were caught in PF traps and Berlsese funnels. This species is present year-round.
