Natural history. P. pennatus specimens were collected manually during the day in a ravine forest; females spin their web on vertical humid rock walls under the shadow of the dense canopy of the trees (Fig. 3C). It shares the same habitat with another linyphiid spider, Gigapassus octarine Miller, 2007, that spins similar webs closely.
