Etymology: In ancient Greek, "kyathos" was a ladle or small dipping cup, and "stoma" meant mouth. Combined, they describe the mouth of these worms, which has a deep, cup-shaped capsule that helps tell them apart from their relatives. The name is a modern scientific coinage, built from those classical roots for the group of small strongyle roundworms that live in the horse's large intestine. The ancient Greeks had no word for these parasites as a group. The singular is "cyathostome," and the plural form is the one used for the whole group.
