A revision of the subfamily Haplorchinae Looss, 1899 (Trematoda: Heterophyidae): I. The Haplorchis group

Price was the first to make extensive use of features of the ventrogenital complex (ventral sucker, gonotyl, genital pore, terminal male duct) and excretory bladder and produced the first reasonable classification of both the family Heterophyidae and the superfamily Opisthorchioidea.

It is inferred from the multiplicity of structure in the terminal genitalia of digenetic trematodes in general, and heterophyids in particular, that they are cross fertilizing despite being hermaphroditic, and it is suggested that variations in terminals may constitute an important mechanical element in isolating mechanisms that separate closely related species.
STUDIES ON THE LIFE CYCLES AND MORPHOLOGY OF THE LARVAL STAGES OF ALARIA ARISAEMOIDES AUGUSTINE AND URIBE, 1927 AND ALARIA CANIS LARUE AND FALLIS, 1936 (TREMATODA: DIPLOSTOMIDAE)

The morphology of the larval stages and the intramolluscan generations is described and observations on the rate of development, hatching of the egg, and swimming of the miracidium of A. arisaemoides and A. canis are given.
On the position of the digenean family Heronimidae: an inquiry into a cladistic classification of the Digenea
- J. Pearson

- 1 February 1992
This analysis concludes that what remains of the data-base is insufficient to support the Heronimidae cladogram and classification, and suggests that better data from the flukes themselves are necessary for a sound cladistic analysis.

C. argentatus from the Bay of Marseille, France, differs from other haplorchine genera in its combination of undivided body, absence of gonotyl, genital pore posterior to ventral sucker, discrete lateral pocket with pilose lining, sucker-like ventrals armed with spines and sclerotized knobs, and thin-walled seminal vesicle.

Confirmation of a polystome from a natural population of Australian lungfish has interesting evolutionary implications and the absence of a true oral sucker is noted.
