New host and locality records for the Ixodes auritulus (Acari: Ixodidae) species group, with a review of host relationships and distribution in the neotropical zoogeographic region
Experimental and Applied Acarology 37 (1-2), 147-156
Abstract: New Neotropical records are presented for ticks belonging to the Ixodes auritulus Neumann, 1904, species group, together with a review of hosts and localities from which members of this complex have previously been collected. The range of the I. auritulus species group is now understood to include Colombia, and 15 bird species are listed as new hosts. From Guatemala to southern Argentina and Chile, specimens of the I. auritulus group have been found on birds belonging to the orders Ciconiiformes, Columbiformes, Falconiformes, Galliformes, Passeriformes, Piciformes, Procellariiformes and Tinamiformes. Passeriform birds are probably the principal hosts, sustaining tick populations throughout the Neotropics. Collection data have yielded four areas - southern South America (from 56° S to 51° S), southern Brazil (25° S-22° S), south-central Peru (14° S-10° S) and Central America (10° N-15° N) - where the I. auritulus group appears to commonly parasitize birds, but additional collections may show that the range of this complex is less discontinuous than currently perceived. Several morphological differences are described for ticks within and among these areas, but it is still unclear whether the I. auritulus group comprises more than one species.
