Introduction

Mammals belonging the carnivore families Canidae (dogs and their relatives) and Felidae (cats and their relatives) are relatively well known due to their large size and charismatic nature. Worldwide, 39 canid and 42 felid species are currently recognized (^{Burgin et al. 2018}); however, the number in Mexico is much smaller at approximately 8 and 6 species, respectively. The ectoparasite fauna (e. g., ticks, mites, fleas, and lice) of these animals has been characterized in the past in separate species descriptions and checklists. For example, ^{Cooley and Kohls (1945)}, ^{Kohls and Clifford (1966)}, and ^{Guzmán-Cornejo et al. (2007a}, ^2007b) are excellent references for ticks and ^{Sánchez-Montes et al. (2018)} is a thorough review of Mexican chewing lice. ^{Hopkins and Rothschild (1966)}, ^{Barnes et al. (1977)}, ^{Muñiz et al. (1981)}, ^{Ayala-Barajas et al. (1988)}, ^{Morales-Muciño and Llorente-Bousquets (1985)}, ^{Morales and Llorente (1986)}, ^{Ponce and Llorente (1996)}, and ^{Acosta et al. (2008)} are just a few of the outstanding references for fleas in Mexico and nationwide. Lastly, ^{Whitaker and Morales-Malacara (2005)} present a comprehensive list of mammal-ectoparasite associations in Mexico, with references to the original literature.

Here, we present a checklist summarizing all major ectoparasite groups from canid and felid species across Mexico. We consolidated information from previously published checklists and searched for new host-parasite records in Web of Science using the following search terms: felid*/canid* AND flea*/tick*/mite*/louse/lice AND Mexico. We also searched for each canid and felid genus known from Mexico with the same parasite search terms above. For each ectoparasite species, we provide taxonomic authority, host associations, collection localities and references, and museum collection information (sometimes with collection number), when available. Some parasite-records are newly reported here after examination of specimens of the U. S. National Tick Collection, Georgia Southern University, Statesboro. Parasite species listed as “sp.” from different localities, host species, or publications may represent different species. All localities listed below are taken directly from the literature or specimen slides. Locality clarifications, if necessary, are listed in brackets following the relevant locality. Collection acronyms are as follows: BMNH = Department of Entomology, The Natural History Museum, London, England; CAIM, InDRE = Colección de Artrópodos con Importancia Médica from Instituto de Diagnóstico y Referencia Epidemiológicos de la Secretaría de Salud, Mexico City; CMNH = Carnegie Museum of Natural History (Traub collection); CNAC = Colección Nacional de Ácaros, Instituto de Biología, Universidad Nacional Autónoma de México; MZFC, SIPHO = Colección de Siphonaptera at the Museo de Zoología Alfonso L. Herrera, Universidad Nacional Autónoma de México, Mexico City, Distrito Federal; NTC = L.G. Neumann Tick Collection, École Nationale Vétérinaire, Toulouse, France; USNTC = U. S. National Tick Collection, Georgia Southern University, Statesboro.

We document a total of approximately 31 tick, 4 mite, 18 flea, and 4 louse species from 10 host species (4 canids and 6 felids) across 29 states from Mexico. These numbers are almost certainly an underestimate, especially given that ectoparasites are only recorded from half of the known Mexican canid species and that several of the ectoparasite taxa listed below could not be identified to species. However, we note that ectoparasite contamination commonly occurs among host species when specimens are not processed carefully. Thus, readers of any checklist should be wary of the potential of incorrect information resulting from contamination. We encourage researchers to carefully process host specimens and publish their findings of both presence and absence of ectoparasites from canid and felid species. We also strongly recommend researchers to deposit ectoparasite specimens in natural history museums. Researchers working with canid and felid species should take all available data from host specimens in the field, including their parasites (e. g., a “holistic” or “extended” specimen; ^{Cook et al. 2016}, ²⁰¹⁷; ^{Webster 2017}; ^{Cook and Light 2019}). Holistic specimens will provide much needed data about parasite fauna and distribution of those fauna such that subsequent studies can be conducted. Lastly, our search of the U. S. National Tick Collection at Georgia Southern University alone resulted in a minimum of 1 previously undescribed host-parasite association, 8 new state records, and 5 parasite associations with a novel host. Thus, future checklists should explore holdings in natural history collections which may result in additional host-parasite associations and locality records.
