Biology. Reared from cobweb spider Theridion evexum Keyserling ( Theridiidae) in Costa Rica (Weng & Barrantes 2007; Barrantes et al. 2008); P. petronae parasitizes medium-sized immatures of the spider, and apparently attacks it inside its retreat. An egg is glued on the antero-lateral dorsal section of the spider’s abdomen (Weng & Barrantes 2007).
