Analysis of sequence variation in the 16S and 12S mitochondrial ribosomal DNA genes suggests that I. scapularis arose in the South but that a large geographic split gave rise to 2 distinct lineages now interbreed and are partially sympatric.
Ixodes (Ixodes) scapularis (Acari:Ixodidae): redescription of all active stages, distribution, hosts, geographical variation, and medical and veterinary importance.

An analysis of tick-host and -habitat associations and biogeographical patterns, in the context of the newly derived phylogenies, suggests that much of the existing host-association patterns may be explained as artifacts of biogeography and ecological specificity.

The distribution pattern of endemic Australian taxa suggests that these lineages, and by extension the Ixodidae, originated after the isolation of Australia in the late Cretaceous, much more recently than previously indicated.
Comparison of the Mitochondrial 12S and 16S Ribosomal Dna Genes in Resolving Phylogenetic Relationships among Hard Ticks (Acari: Ixodidae)
- D. Norris, J. Klompen, W. Black
- Biology
- 1999
Although the 12S and 16S genes resolved intrageneric and intraspecific relationships, the lack of resolution among higher taxonomic groups appears to be caused by homoplasy arising from the high A/T content and a high overall mutation rate in the tick mitochondrial genome.
Systematic relationships in the soft ticks (Acari: Ixodida: Argasidae)
- J. Klompen, J. Oliver
- Biology
- 1 October 1993
A phylogenetic analysis of relationships at the generic to subgeneric level is carried out for the family Argasidae, finding that some lineages provide a substantially better overall fit to the data than any of the hypotheses derived from existing classifications of the family.
Idiosomal lyrifissures, Setae, and small glands as taxonomic characters and potential indicators of ancestral segmentation patterns in larval ixodidae (Acari: Ixodida)

Abstract Variability in idiosomal chaetotaxy, lyrifissure, and gland patterns among ixodid larvae is assessed based on a comparative analysis of these structures in 53 species of ixodid ticks. A…

The 18S phylogeny supports the earlier 16S based phylogeny in placing members of Hyalomminae on a common branch with members of the Rhipicephalinae and in indicating long branch lengths among soft tick taxa.
Phylogenetic relationships in the mite family Sarcoptidae (Acari: Astigmata).

A phylogenetic analysis of the relationships among the 117 recognizable species of the mite family Sarcoptidae Murray, 1877 is carried out based on 215 morphological and ontogenetic characters.
Prelarva and larva of Opilioacarus (Neocarus) texanus (Chamberlin and Mulaik) (Acari: Opilioacarida) with notes on the patterns of setae and lyrifissures
- J. Klompen
- Biology
- 1 October 2000
The distribution pattern of lyrifissures and setae on the hysterosoma of opilioacarid larvae appears to be the most complete pattern of these structures in the order Parasitiformes, and strongly suggests an ancestral segmental arrangement of the cuticular sensillae and glands.
