PARAENSE, W. Lobato. Halipegus dubius Klein, 1905 (Trematoda, Hemiuridae): a redescription, with notes on the working of the ovarian complex. Mem. Inst. Oswaldo Cruz [online]. 1992, vol.87, suppl.1, pp. 179-190. ISSN 1678-8060.

A redescription of Halipegus dubius Klein, 1905, of Brazilian frogs Leptodactylus pentadactylus and L. ocellatus, is presented. The parasite was found exclusively in the buccal cavity, in number varying from 1 (in most instances) to 3, and exceptionally 25 (one instance). Morphological data were based on 40 whole-mounted specimens and 4 serially sectioned ones. Larval development takes place in planorbid snails (Biomphalaria glabrata and B. tenagophila) and in an undetermined species of cyclops. Working of the ovarian complex was followed by microscopical observation of life specimens. Constrating with the similarity of the four American species of Halipegus currently recognized as valid, they can be easily separated by the characters of their cercariae.
