  Cestoda - Wikipedia, the free encyclopedia
There are two subclasses in class Cestoda, the Cestodaria and the Eucestoda.
By far the most common and widespread are the Eucestoda, with only a few species of unusual worms in subclass Cestodaria.
The cyclophyllideans are of the most importance to humans because they infect people and livestock.

 The Class Cestoda (Tapeworms)
The traditional adult tapeworm is little more than a head with a complicated set of hooks to hang on with and a continuously produced series of reproductive segments behind this.
The adult body consists of a head, called a 'Scolex' which is distinguished by the presence of suckers and hooks, though the hooks may be absent as in Taenia saginatus.
Within the Subclass Eucestoda those species which infect mankind can be found in two orders, Pseudophyllidea and Cyclophyllidea which can be recognised by their different life cycles, see diagrams below.

 Amphilinidea
The amphilinids are large worms (several cm long) which, in contrast to the true tapeworms (Eucestoda), have a flattened leaf-like body that is not divided into proglottids (false "segments").
Larvae have 10 peculiarly shaped hooks of several types at the posterior end, which are retained by the adult.

 ARS | Publication request: Phylogeny among Orders of the Eucestoda (Cercomeromorphae): Integrating Morphology, ...   (Site not responding. Last check: )
This is significant in establishing a broader context for understanding the host and geographic histories for economically important tapeworms that infect domestic stock and humans.
Complementary strategies for analysis used (1.) A top-down approach using a consensus matrix for molecular and morphological characters for 13 orders; and (2.) A bottom-up approach using a comprehensive matrix for 47 ingroup taxa.
Phylogenetic resolution among the orders of the Eucestoda will lead to development of model systems for evolutionary biology, cospeciation analyses, and studies of historical biogeography.
