We recognize this group by the following characters, in the male copulatory organs: 1) tegulum strongly protruding ventrad (Figs 1–16), and (2) terminal apophysis prominent, characteristically connected to palea (Figs 59–66, 75–84); and in the epigyne: 3) comparatively long and narrow anterior part with one pocket (hood) in front, followed by wide posterior part with cavities (atrium) more or less filled out by septum (Figs 90–94, 96–97) (exception: P. nigra, Fig. 95).
