In the present study, we describe a new species of the genus\n Monoecocestus<\/jats:italic>\n parasitizing the southern vizcacha,\n Lagidium viscacia<\/jats:italic>\n , based on specimens collected in Puno, Peru, at an elevation of 3932 m a. s. l. A total of 45 specimens of the new species were obtained and processed for morphological and molecular analysis. For molecular analysis, DNA sequences of three markers were generated: the nuclear 18S, 28S, ITS, and mitochondrial\n cox<\/jats:italic>\n 1. The molecular data were compared with sequences available in GenBank, confirming its inclusion in the genus\n Monoecocestus.<\/jats:italic>\n Morphologically, the new species is similar to\n M. threlkeldi<\/jats:italic>\n , but it can be distinguished by its smaller body size, scolex, cirrus pouch, and number of proglottides. The description of the new species\n Monoecocestus viscaciae<\/jats:italic>\n improves our understanding of the diversity of cestodes in high-altitude Andean ecosystems and provides new insights into host specificity within the genus\n Lagidium.<\/jats:italic>\n <\/jats:p>","DOI":"10.1017\/s0022149x26101655","type":"journal-article","created":{"date-parts":[[2026,6,24]],"date-time":"2026-06-24T06:59:03Z","timestamp":1782284343000},"source":"Crossref","is-referenced-by-count":0,"title":["A new species of the genus\n Monoecocestus<\/i>\n (Cestoda: Anoplocephalidae) from\n Lagidium viscacia<\/i>\n (Rodentia: Chinchillidae) from the high-altitudes of Peru"],"prefix":"10.1017","volume":"100","author":[{"given":"H.","family":"Apaza-A\u00f1amuro","sequence":"first","affiliation":[{"name":"Universidad Nacional del Altiplano-Puno"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"C.","family":"Zapata","sequence":"additional","affiliation":[{"name":"Universidad Nacional del Altiplano-Puno"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0006-3658-6439","authenticated-orcid":false,"given":"D.","family":"Coronado-Morones","sequence":"additional","affiliation":[{"name":"Universidad Nacional Aut\u00f3noma de M\u00e9xico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9229-1321","authenticated-orcid":false,"given":"G.","family":"Torres-Carrera","sequence":"additional","affiliation":[{"name":"Universidad Nacional Aut\u00f3noma de M\u00e9xico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"L.","family":"Garcia-Prieto","sequence":"additional","affiliation":[{"name":"Instituto de Biolog\u00eda, UNAM"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A.","family":"Oceguera-Figueroa","sequence":"additional","affiliation":[{"name":"Instituto de Biolog\u00eda, UNAM"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2026,6,24]]},"reference":[{"key":"S0022149X26101655_r14","doi-asserted-by":"publisher","DOI":"10.1645\/GE-1830.1"},{"key":"S0022149X26101655_r3","first-page":"374","volume-title":"T\u00e9cnicas de captura para aves y mam\u00edferos","author":"Bautista","year":"2011"},{"key":"S0022149X26101655_r8","doi-asserted-by":"publisher","DOI":"10.14411\/fp.2009.025"},{"key":"S0022149X26101655_r5","doi-asserted-by":"publisher","DOI":"10.1016\/0001-706X(93)90079-Q"},{"key":"S0022149X26101655_r11","doi-asserted-by":"publisher","DOI":"10.1016\/j.parint.2015.02.008"},{"key":"S0022149X26101655_r15","doi-asserted-by":"publisher","DOI":"10.1645\/GE-2089.1"},{"key":"S0022149X26101655_r20","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijpara.2005.02.014"},{"key":"S0022149X26101655_r16","volume-title":"Manual de t\u00e9cnicas para preparar y estudiar los par\u00e1sitos de animales silvestres","author":"Lamothe-Argumedo","year":"1997"},{"key":"S0022149X26101655_r19","doi-asserted-by":"publisher","DOI":"10.11646\/zootaxa.5380.1.3"},{"key":"S0022149X26101655_r22","doi-asserted-by":"crossref","first-page":"819","DOI":"10.1163\/156854106779799178","article-title":"Molecular phylogeny of Acrobeloides and Cephalobus (Nematoda: Cephalobidae) reveals paraphyletic taxa and recurrent evolution of simple labial morphology","volume":"8","author":"Smythe","year":"2006","journal-title":"Nematology"},{"key":"S0022149X26101655_r13","doi-asserted-by":"publisher","DOI":"10.1007\/978-4-431-36025-4_3"},{"key":"S0022149X26101655_r10","doi-asserted-by":"publisher","DOI":"10.1023\/A:1022589725500"},{"key":"S0022149X26101655_r21","doi-asserted-by":"publisher","DOI":"10.2307\/3273946"},{"key":"S0022149X26101655_r9","doi-asserted-by":"publisher","DOI":"10.14411\/fp.2025.023"},{"key":"S0022149X26101655_r2","volume-title":"Reference Manual on Euthanasia","year":"2013"},{"key":"S0022149X26101655_r6","unstructured":"Caira, JN , Jensen, K and Barbeau, E (eds) (2022) Global Cestode Database.
