Its geographical range is expanding towards the Pacific coast of Central America by crossing the Darien rainforest. In Ecuador, its presence has been poorly documented and remains ecologically ambiguous. In this study, we confirm the presence of\n                    <jats:italic>C. thous<\/jats:italic>\n                    in north-eastern Ecuador based on two roadkill specimens collected in Sucumb\u00edos Province and two independent photographic records from Yasuni National Park, which were obtained through systematic camera-trapping. Stomach-content analysis revealed a predominantly insectivorous and opportunistic diet which includes insects, arachnids, reptiles, and amphibians. In addition, an ectoparasite analysis found parasitism by the introduced cattle tick\n                    <jats:italic>Rhipicephalus microplus<\/jats:italic>\n                    , highlighting potential risks of pathogen transmission between domestic animals and wildlife. Mitochondrial cytochrome b sequences from form a well-supported distinct haplotype from other South American lineages, suggesting that forest-dwelling foxes in eastern Ecuador may represent a separate evolutionary unit with unique ecological adaptations to rainforest environments. These findings underscore the importance of continued monitoring of\n                    <jats:italic>C. thous<\/jats:italic>\n                    in the Amazon, particularly in the context of road expansion, habitat alteration, and increasing interactions with domestic animals such as domestic dogs. Our results have implications for taxonomic assessment, ecological understanding, and conservation planning of this widespread, yet understudied, Neotropical canid in Ecuador.\n                  <\/jats:p>","DOI":"10.3897\/zookeys.1266.162023","type":"journal-article","created":{"date-parts":[[2026,1,8]],"date-time":"2026-01-08T14:01:59Z","timestamp":1767880919000},"page":"103-125","source":"Crossref","is-referenced-by-count":0,"title":["Forest-dwelling crab-eating foxes, Cerdocyon thous (Carnivora, Canidae), in eastern Ecuador: new ecological and genetic records of an elusive Neotropical canid"],"prefix":"10.3897","volume":"1266","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5846-2230","authenticated-orcid":true,"given":"Fernando","family":"Anaguano-Yancha","sequence":"first","affiliation":[{"name":"Wildlife Conservation Society, Programa Ecuador, Quito, Ecuador"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6956-570X","authenticated-orcid":true,"given":"Ana Luc\u00eda","family":"Pilatasig","sequence":"additional","affiliation":[{"name":"Pontificia Universidad Cat\u00f3lica del Ecuador, Quito, Ecuador"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-2442-7612","authenticated-orcid":true,"given":"Laura","family":"Simba","sequence":"additional","affiliation":[{"name":"Instituto Nacional de Biodiversidad, Quito, Ecuador"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8060-2252","authenticated-orcid":true,"given":"Mauricio","family":"Herrera-Madrid","sequence":"additional","affiliation":[{"name":"Instituto Nacional de Biodiversidad, Quito, Ecuador"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3508-5078","authenticated-orcid":true,"given":"Galo","family":"Zapata-R\u00edos","sequence":"additional","affiliation":[{"name":"Wildlife Conservation Society, Programa Ecuador, Quito, Ecuador"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3410-6669","authenticated-orcid":true,"given":"Jorge","family":"Brito","sequence":"additional","affiliation":[{"name":"Instituto Nacional de Biodiversidad, Quito, Ecuador"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"2258","published-online":{"date-parts":[[2026,1,8]]},"reference":[{"key":"162023_B1","doi-asserted-by":"publisher","DOI":"10.19137\/cienvet-202123105"},{"key":"162023_B2","doi-asserted-by":"publisher","DOI":"10.12933\/therya_notes-23-132"},{"key":"162023_B3","doi-asserted-by":"publisher","DOI":"10.7818\/ECOS.2017.26-3.08"},{"key":"162023_B4","author":"Benavides Melo","year":"2021","journal-title":"Necropsia en caninos."},{"key":"162023_B5","doi-asserted-by":"publisher","DOI":"10.2307\/3503974"},{"key":"162023_B6","doi-asserted-by":"publisher","DOI":"10.1515\/mamm.1988.52.2.181"},{"key":"162023_B7","doi-asserted-by":"publisher","DOI":"10.3390\/pathogens9100818"},{"key":"162023_B8","doi-asserted-by":"publisher","DOI":"10.4404\/hystrix-27.2-11433"},{"key":"162023_B9","doi-asserted-by":"publisher","DOI":"10.4067\/S0716-078X2004000100002"},{"issue":"1","key":"162023_B10","first-page":"55","article-title":"Diversity of mammals and birds recorded with camera-traps in the Paraguayan Humid Chaco.","volume":"24","author":"Caballero-Gini","year":"2020","journal-title":"Bolet\u00edn del Museo Nacional de Historia Natural del Paraguay"},{"key":"162023_B11","doi-asserted-by":"publisher","DOI":"10.2307\/1373806"},{"issue":"1","key":"162023_B12","first-page":"1","article-title":"Cat\u00e1logo de los mam\u00edferos de Am\u00e9rica del Sur.
