Remarks
- Biology: Occurring on the twigs and stems of its host plants.
- Economic Importance: This species may cause disfiguration of nursery plants (Miller & Appleby, 1971).
- General Remarks: Good description and illustration of the adult female given by Ferris (1950b) and by McKenzie (1967) and by Miller & Appleby (1971). Good description and illustration of the adult male given by Miller & Appleby (1971). Good description and illustration of the immature stages of female and male given by Miller & Appleby (1971). Hollinger (1923) redescribed the same species, as if a new species. Miller & Appleby (1971) question the synonymy of P. regnillhoi with P. dearnessi.
