Complete type catalog of Trombiculidae sensu lato (Acari: Trombidiformes) of the U.S. National Entomology Collection, Smithsonian Institution

Abstract

Mites in the family Trombiculidae sensu lato are parasites of terrestrial vertebrates, even humans, in their larval stage. There are more than 3,700 species of chiggers, and about one-third of these species are represented by type specimens in the Smithsonian Institution’s United States National Museum Entomology Collection. Here we provide a catalog of all primary and secondary type specimens of chiggers (holotype, paratype, syntype, lectotype, and paralectotype) housed in the collection. Listed herein are 1,026 type specimens with 645 representing holotypes, 782 paratypes, 69 syntypes, 19 lectotypes, and 16 paralectotypes of larvae, deutonymphs, and adult chiggers.
