Introduction

The mites known as “chiggers” or “chigger mites” belong to three families: Ewing, 1944, Womersley, 1944, and Ewing, 1946 sensu Wen (1999). The larvae are ectoparasites of vertebrates, and during the parasitism, they liquefy and suck the host’s epithelial tissue by the enzymatic action of their saliva. Blood is not ingested in this process, but some blood cells can be found in the gut of the mite (Jones 1950). Deutonymphs and adults are free living predators (Crossley 1960). Studies of the biology and taxonomy of these mites were intensified during World War II, thus increasing considerably the number of known species. Soldiers were attacked in encampments and contracted rickettsioses from infected larvae (Wharton and Fuller 1952). According to these authors, in the front of the situation, the public health departments were faced with the need for cataloging studies, description, morphology, and biology of these mites. Although they are considered potential vectors of pathogens, the role of these mites in the epidemiology of rickettsiosis is unknown in the Neotropical region (Azad and Beard 1998, Poinar and Poinar 1998). In South America, the countries that have a checklist of chiggers species are: Venezuela (Brennan and Reed 1975), Peru (Brennan and Jones 1961), Surinam (Brennan and Lukoschus 1971) and recently Chile (Stekolnikov and González-Acuña 2015). Ewing (1931) compiled the first list of chigger mites from the New World, eight species from Brazil. Wharton and Fuller (1952) increased the number by eight genera and 18 species. Fonseca (1955) reported the first human hosts for Brazil. Brennan and Goff (1977) reported 87 chigger genera for the Nearctic and Neotropical regions, of which 18 were recorded from Brazil. The Brazilian territory is composed by five regions (north, northeast, central-west, southeast and south), 26 states and one federal district (Contel 2014). Between the 1970s and 1990s, new species were described by various researchers from specimens collected primarily in the northern and central-western parts of the country, but have never been summarized (Stekolnikov and González-Acuña 2015). Therefore, here we are compiling a checklist of species from Brazil, including new hosts and localities.

Materials and methods

In the checklist, the taxa comprise two families, and . The genera and species are arranged alphabetically, in the follow format: Genus - Valid name, author and data; Species – Checklist number, valid name of species, author, date, type locality, host, and type depository, in parenthesis are the typification and the collection number, when available. In cases where the original host name has changed, the current host name is listed with the original host name in parenthesis. The host species were updated based on the IUCN (2017). The following abbreviations were used: USA, Hawaii, Honolulu, Bernice Pauahi Bishop Museum; USA, Illinois, Chicago, Field Museum of Natural History Chicago (cited in original description as CNHM); Brazil, São Paulo, São Paulo, Instituto Butantan; Brazil, Rio de Janeiro, São Cristovão, Universidade do Rio Janeiro, Museu Nacional; Brazil, São Paulo, São Paulo, Universidade de São Paulo; United Kingdom, London, The Natural History Museum [formerly British Museum (Natural History)] (cited in original description as BMNH or BM); USA, Oklahoma, Norman, University of Oklahoma, Oklahoma Museum of Natural History; USA, Ohio, Columbus, Ohio State University Acarology Laboratory; Netherlands, Leiden, Naturalis Biodiversity Centre [formerly Rijksmuseum van Natuurlijke Historie]; Australia, South Australia, Adelaide, South Australian Museum; USA, Washington D.C., National Museum of Natural History, [formerly United States National Museum] which is housed at the Systematic Entomology Laboratory (BARC-USDA-ARS), cited in original descriptions as NMNH. Details of the records in Brazil were provided based on the bibliographic review, followed to the new records for the country, when available. The new records from the checklist are based on the material deposited in the IBSP collection. Some of these species were also reported outside Brazilian territory. These recordings of literature were included in other records. In addition, a list of chiggers from Brazil is summarized with their respective hosts (Appendix 1) and a list of vertebrate hosts and their respective chiggers and the published information from Brazil (Appendix 2).

Results

A Brazilian checklist with eight species of the family and 55 of the family , totaling 63 chigger species in 30 genera from approximately 70 different hosts is presented. Some regions just have one or two chigger records and most of these records are represented by the type series. Species of the family Walchiidade were never recorded in the Brazilian territory until this work. The chigger species , , , and are reported for the first time in Brazil, and new records of locality for and new localities and hosts for the species , , , , and are provided too.
