Karl (1967) reported 8 species of shore birds of California naturally infected with P. altmani, with C. semipalmatus being the most heavily infected species. His morphometrics were based on emended description of specimens obtained from his heavily infected experimental hosts, the duckling Anas platyrhynchus Linn. Common measurements of proboscis, hooks, neck, spine, receptacle and lemnisci were the same for both sexes.
