This is the second of three volumes of "Keys to the Trematoda," a series on the systematics and identification of the Class Trematoda. The book presents the taxa in the Order "Echinostomida" and some of those in the Order "Plagiorchiida," with keys for their identification at the superfamily, family, subfamily and generic levels. The keys are based on critical examination of specimens by subject experts, and generic diagnoses are accompanied by illustrations of important morphological characters. This volume includes seven echinostomidan superfamilies (the echinostomatoids, haploporoids, haplosplanchnoids, heronimoids, microscaphidioids, paramphistomatoids and pronocephaloids) and two plagiorchiidan superfamilies (the allocreadioids and lepocreadioids). The first volume covered the Subclass "Aspidogastrea" and Order "Strigeida," while the third volume, due to be published in early 2006, will cover the remaining members of the Plagiorchiida.

Most previous publications on the classification of tapeworms (cestodes) have been based on compilations from the literature and are now dated. Thus there is a real need for up-to-date keys based on the re-examination of specimens and on a re-evaluation of the characters employed in cestode taxonomy. This book fulfils this need and provides keys to enable specialists and non-specialists to identify cestodes to generic level. The keys are dichotomous and are based largely on morphological characters. The authors have re-examined many specimens, including type specimens where possible. As a result, the keys reflect new ideas and have lead to reappraisals of cestode taxonomy, particularly at family and generic level, with many reallocations and synonymies. The authors include 19 international authorities from the UK, USA, Australia, Brazil, France, Norway, Italy, Switzerland, Poland, Bulgaria and the Ukraine. The book includes approximately 1,700 illustrations and is a standard work on tapeworm identification and will be indispensable for parasitologists.

This is the third of three volumes of "Keys to the Trematoda," a series on the systematics and identification of the Class Trematoda. It covers five superfamilies with the Order "Plagiorchiida" and the family "Didymozoidae," with the keys for their identification at the family, subfamily and generic levels. It also includes a key to all dignean superfamilies, including those treated in detail in volumes one and two.

This book, in three volumes, presents a detailed revision of the systematics and taxonomy of the platyhelminth class "Trematoda," subclasses "Aspidogastrea" and "Digenea," with keys for the identification of these parasites at the superfamily, family, subfamily and generic levels.The trematodes are parasitic worms infecting all vertebrate groups and include families of significance to human and animal health, with considerable economic impact. Volume 1 covers the subclass "Aspidogastrea" and order "Strigeida," while the second and third volumes will cover the orders "Echinostomida" and "Plagiorchiida."
