The ozobranchid leech, Ozobranchus margoi (Apáthy, 1890), parasite of the loggerhead turtle, Caretta caretta (Linnæus), was described through a multilevel approach including three different techniques: scanning electronic microscopy, histology and micro-CT.

Redescription of the duck leech, Theromyzon rude (Baird, 1869) (Rhynchobdellida: Glossiphoniidae)
Canadian Journal of Zoology, 1992The identification of the species of Theromyzon in North America and worldwide is based on the number of annuli separating the male and female gonopores. The first species identified from North America (Glossiphonia rudis) was not fully described but, based on the collection of a specimen from the same site, T.

One of 4 (25%) white crappie, Pomoxis annularis, specimens from the Ouachita River, Dallas County, Arkansas, was found to be infested with 8 glossiphoniid leeches, Actinobdella inequiannulata Moore, 1901. Leeches were removed from within the operculum on gills and gill arches.

In this study, two new species of Helobdella leeches, Helobdella octatestisaca n. sp. and Helobdella melananus n. sp., and a newly recorded species, Helobdella europaea, are reported. Morphological characters and DNA barcode analysis were used to identify the three new species.

A new species of duck leech, Theromyzon bifarium, is described which, like T. rude and T. maculosum, has the gonopores separated by two annuli. Theromyzon bifarium is distinguished by the presence of a cylindrical male atrium, paired dorsolateral male ducts which enter the atrium separately, and a posteriorly directed loop formed by the long common ...

Desserobdella phalera (Graf, 1899) n.comb. is redescribed. This glossiphoniid leech deposits cocoons directly onto the substratum and belongs, therefore, in the subfamily Glossiphoniinae. It has the following generic characters: diffuse salivary glands, two pairs of coalesced eyes, one pair of mycetomes, and subdivision of primary annuli in complete ...

Abstract 1. Each salivary gland cell of Oosthuizobdella extends a single process (ductule) anteriorly into the proboscis. Secretion occurs at the ductule ending. 2. The cells produce calcium-dependent action potentials, accompanied by secretion, in response to stimulation of the stomatogastric nerve or to addition of 5-hydroxytryptamine (10 −4 M),
