Revision Of The Genus Monatractides (Parasitengona, Torrenticolidae) Of The United States And Canada: New Species, Re-Descriptions, Phylogenetics, And A Key To Species, Whitney Anne Nelson Dec 2018

Revision Of The Genus Monatractides (Parasitengona, Torrenticolidae) Of The United States And Canada: New Species, Re-Descriptions, Phylogenetics, And A Key To Species, Whitney Anne Nelson

Graduate Theses and Dissertations

The full suite of known Monatractides (Parasitengona, Torrenticolidae) taxa of North America (north of Mexico) are investigated herein using integrative methods. Species hypotheses are supported with morphology, geography, and phylogenetic analysis of the barcoding region of COI for 154 individuals from over 100 localities. Relationships between species are examined with a combined analysis of COI and 28S rDNA for 55 specimens. Previously described species are examined and re-described with color images and updated information, where possible. Our results indicate the need to synonymize two species: M. californica (Marshall, 1943) is a junior synonym of M. geographica (Marshall, 1943). We describe …


Integrative Taxonomy Of North American Torrent Mites (Parasitengona: Torrenticolidae: Torrenticola), Jon Ray Fisher May 2016

Integrative Taxonomy Of North American Torrent Mites (Parasitengona: Torrenticolidae: Torrenticola), Jon Ray Fisher

Graduate Theses and Dissertations

Mites are notorious for being under-studied and incomplete knowledge of distribution, life-history, and morphology are commonplace. They typically gain attention through the relatively few pest species that plague our crops, pets, or bodies. Despite representing a successful radiation with an estimated 3–5 million species, relatively few mite lineages attract research attention from non-acarologists. However, the largest radiation of all mites—Parasitengona—has potential to bridge the gap between specialists and non-specialists. Parasitengona are the butterflies of the mite world. Obvious are the bright red mites searching for pollen on concrete, or the large, furry velvet mites coming out to mate after spring …
