Adult females of the blacklegged tick, Ixodes scapularis (Acari: Ixodidae), were collected from a North American porcupine, Erethizon dorsatum, in eastern Ontario, Canada. This porcupine parasitism indicates that an established population of I. scapularis is present in the local vicinity. This tick species is known to parasitize more than 150 different vertebrate hosts, including the North American porcupine. The presence of I. scapularis ticks parasitizing a North American porcupine constitutes a new tick-host record in Canada.

Established Population

This study provides a novel method of documenting established populations of bird-feeding ticks. Single populations of the blacklegged tick, Ixodes scapularis, and the rabbit tick, Haemaphysalis leporispalustris, were revealed in southwestern Québec, Canada. Blacklegged tick nymphs and, similarly, larval and nymphal rabbit ticks were tested for the Lyme disease bacterium, Borrelia burgdorferi sensu lato (Bbsl), using PCR and the flagellin (flaB) gene, and 14 (42%) of 33 of blacklegged tick nymphs tested were positive. In contrast, larval and nymphal H. leporsipalustris ticks were negative for Bbsl. The occurrence of Bbsl in I. scapularis nymphs brings to light the presence of a Lyme disease endemic area at this songbird nesting locality. Because our findings denote that this area is a Lyme disease endemic area, and I. scapularis is a human-biting tick, local residents and outdoor workers must take preventive measures to avoid tick bites. Furthermore, local healthcare practitioners must include Lyme disease in their differential diagnosis.

Base Of The Tongue

We document the first report of a blacklegged tick, Ixodes scapularis Say, parasitizing an American Kestrel, Falco sparverius Linnaeus (Falconiformes: Falconidae), in Canada. A fully engorged I. scapularis nymph was collected from the base of the tongue of an American Kestrel nestling recovered at Mirabel, Québec. This nestling had recently fledged the nest, and was exposed to I. scapularis immatures that were host-seeking in the surrounding low-level vegetation. DNA barcoding was used to confirm the identification of the tick. Primers of the flagellin (fla) gene were employed to determine whether the Lyme disease spirochete, Borrelia burgdorferi sensu lato (s.l.) Johnson, Schmid, Hyde, Steigerwalt & Brenner, was present in the I. scapularis nymph; the tick was negative. We provide the first report of I. scapularis parasitizing a raptor in Canada and, likewise, the first account of this tick species attached to the oral cavity of a bird. Moreover, this bird parasitism is the first documentation of a tick on a falconid bird in Canada.

High Degree

The phylogenetic relationships of Glossiphoniidae, a leech family characterised by its high degree of parental care, were investigated with the combined use of morphological data and three molecular datasets. There was strong support for monophyly of most accepted genera in the group, many of which are consistent with eyespot morphology. The genera Desserobdella Barta & Sawyer, 1990 and Oligobdella Moore, 1918 are suppressed as junior synonyms of Placobdella Blanchard, 1893 and thus recognising each of Placobdella picta (Verrill, 1872) Moore, 1906, Placobdella phalera (Graf, 1899) Moore, 1906, and Placobdella biannulata (Moore, 1900), comb. nov. The species Glossiphonia elegans (Verrill, 1872) Castle, 1900 and Helobdella modesta (Verrill, 1872), comb. nov. are resurrected for the North American counterparts to European non-sanguivorous species. Glossphonia baicalensis (Stschegolew, 1922), comb. nov. is removed from the genus Torix Blanchard 1898 and Alboglossiphonia quadrata (Moore, 1949) Sawyer, 1986 is removed from the genus Hemiclepsis Vejdovsky, 1884. The biogeographic implications of the phylogenetic hypothesis are evaluated in the context of what is already known for vertebrate hosts and Tertiary continental arrangements.
