Eurasia and Africa.

HABITAT

Parasitic in plovers, mostly in ringed plover (Charadrius hiatic-ula) and snowy plover (Charadrius alexandrinus). Most of the records are from seashores or salt lakes, which seem to be the macrohabitats of this parasite.

FEEDING ECOLOGY AND DIET

Intestinal parasite absorbing nutrients through the tegument.

BEHAVIOR

REPRODUCTIVE BIOLOGY

Progynotaenia odhneri is hermaphroditic. However, it does not possess a vagina. The copulation is traumatic: the heavily armed cirrus penetrates through the tegument and the parenchyma and directly inseminates the seminal receptacle. The intermediate hosts of this species are not known.
