Cyclophyllidea ( kyklofy'lɪdɛa , also tsy- ) is an order of tapeworms . It comprises more than half of the known tapeworms, making it the most species-rich order of this class. Many species of this order are clinically important parasites in humans and animals.

features

All Cyclophyllidea have many limbs ( proglottids ) and four suction cups on the tapeworm head ( Scolex ). The genital pores of the proglottids are mostly unilateral, only the representatives of the Dilepididae have genital pores arranged on both sides. There is a compact yolk gland ( Vitellarium ) behind the ovary .

Systematics

The Cyclophyllidea are divided into several families (selected families, genera and species):

• Family Anoplocephalidae

• Family Catenotaeniidae
• Family Davanineidae
• Dilepidiadae family
• Family Dipylidiidae
  • Genus Dipylidium , causing dipylidiosis in Carnivora
    • Cucumber tapeworm ( Dipylidium caninum ), worldwide, affects dogs and cats
    • Dipylidium oerleyi
    • Dipylidium porimamillanum
    • Dipylidium sexcoronatum
  • Genus Joyeuxiella Fuhrmann, 1935
    • Joyeuxiella echinorhynchoides

    • Diplopylidium acanthotretum
    • Diplopylidium monoophorum
    • Diplopylidium noelleri
    • Diplopylidium quinquecoronatum
• Family Gryporhynchidae
