Species (Geographical location)Length of spiniger-like chaetae (µm)Dorsal simple chaetaeAciculaeLength of pharynx (chaetigers)proventricle (chaetigers) / no. of rows ofShape of posterior falcigersReferencesP. articulata (Kudenov & Harris, 1995) (California)950–1000Unidentate on first chaetigers then becoming progressively bidentateDiamond shaped on the tip at the anterior part of the body, progressively blunt along the body~6–7~5 / 22–24Bidentate, proximal tooth slightly longer and widter than distal one. Both sharpKudenov & Harris (1995)P. dionisi (Núñez y San Martín, 1991) (Canary Islands and Western Mediterranean Sea)51–54Moderately thick, not bifid strongly serrated marginsThin, distal thickening with small tip~12~7 / 30Bidentate, proximal tooth thicker than distal one, c shaped. Short subdistal spinesNüñez & San Martín (1991); San Martín (2003)P. ehlersiaeformis (Augener, 1913) (Australia)50–47Bifid with short subdistal spinesDistally acuminate, lancet-shaped75 / 21Bidentate, proximal tooth much thicker than distal one, bent at right angle respect to it or slightly curved towards shaft.
