Annelida (Clitellata): Oligochaeta, Branchiobdellida, Hirudinida, and Acanthobdellida
The chapter describes the ecology, life history, anatomy, morphology, ecology, evolution, and physiology of oligochaetes, branchiobdellidans, leeches, and acanthOBdellids found in North America. Expand
Redescription of Placobdella parasitica (Say, 1824) Moore, 1901 (Hirudinida: Glossiphoniidae)
Leeches collected during May and June, 2012, from Minnesota, USA, were consistent with P. parasitica (Say, 1824) Moore, 1901 as described by Say (1824), and the acquisition of these specimens from the type locality facilitated redescription of P. Parasitica. Expand
Leeches (Annelida: Hirudinida) of Northern Arkansas
Twenty-one lotic and lentic environments throughout central and northern Arkansas were surveyed for the presence of leeches during June 2004 and April, July - October 2005 and five species are reported from Arkansas for the first time. Expand
Resurrection and Redescription of Placobdella rugosa (Verrill, 1874) (Hirudinida: Glossiphoniidae)
Leeches collected on August 5 and 6, 2011, from North Dakota, USA, the type locality of Clepsine ornata rugosa Verrill, were determined to be conspecific with Placobdella rugosa (Verrill, 1874) Moore, 1901 on the basis of comparison to the syntype series. Expand
Placobdella cryptobranchii (Rhynchobdellida: Glossiphoniidae) on Cryptobranchus alleganiensis bishopi (Ozark Hellbender) in Arkansas and Missouri
The dorsal pigmentation of live specimens of P. cryptobranchii is described for the first time and there were no significant differences in prevalence and mean intensity among various years and localities sampled. Expand
Phylum Annelida: bristleworms, earthworms, leeches
Redescription of Placobdella ornata (Verrill, 1872) (Hirudinida: Glossiphoniidae)
ABSTRACT The taxonomy of papillated leeches of the genus Placobdella has been extremely problematic, confounded by vague descriptions, redescriptions of species using material across a wideExpand
Morphological and molecular characterization of a new species of leech (Glossiphoniidae, Hirudinida): Implications for the health of its imperiled amphibian host (Cryptobranchus alleganiensis)
A significant positive relationship between hellbender body size and the intensity of parasitism is found, and the possibility that the behavioral ecology of adults leading up to reproduction may increase their encounter rates with parasites is suggested. Expand
Distribution of Placobdella ornata (Verrill, 1872) (Hirudinida: Glossiphoniidae)
New collections and redetermination of museum specimens revealed 24 new locality records for Placobdella ornata, including the first reports of the species in New York and Rhode Island. Expand
A new species of leech of the genus Placobdella (Hirudinida, Glossiphoniidae) from the American alligator (Alligator mississippiensis) in Mississippi, USA
A new species of Placobdella siddalli Richardson & Moser was collected from the feet and lower jaw of a single female alligator from the Pascagoula River Wildlife Management Area, George County, Mississippi, and was named in honor of Dr. Mark Siddall. Expand
