Using morphological and molecular tools, we described a novel haemogregarine species infecting the common lancehead snake\n B. atrox<\/jats:italic>\n from Eastern Amazonia, Brazil.\n Hepatozoon atrocis<\/jats:italic>\n sp. nov. has mature gamonts that are morphologically distinct from those reported in the literature, which are often compact, with dispersed or encapsulated cytoplasm and chromatin. In the phylogeny recovered from the 18S rRNA gene, the\n Hepatozoon atrocis<\/jats:italic>\n sp. nov. sequences formed a new clade, comprising a sister group to\n Hepatozoon<\/jats:italic>\n spp. detected in other snakes, anurans, lizards and marsupials. This study reports the first\n Hepatozoon<\/jats:italic>\n species described in the common lancehead snake. In addition, it provides a robust review of haemogregarine species infecting viperids from all over the world.\n <\/jats:p>","DOI":"10.1017\/s0031182025101388","type":"journal-article","created":{"date-parts":[[2025,12,12]],"date-time":"2025-12-12T11:02:32Z","timestamp":1765537352000},"page":"1-16","update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":0,"title":["A new species of\n Hepatozoon<\/i>\n in the common lancehead snake (\n Bothrops atrox<\/i>\n ) from the Eastern Amazonia region"],"prefix":"10.1017","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1180-6715","authenticated-orcid":false,"given":"Fabiane","family":"Rocha de Paula","sequence":"first","affiliation":[{"name":"Instituto Oswaldo Cruz, IOC\/Fiocruz"},{"name":"Instituto Le\u00f4nidas e Maria Deane, Fiocruz Amaz\u00f4nia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7543-168X","authenticated-orcid":false,"given":"Amanda Maria","family":"Picelli","sequence":"additional","affiliation":[{"name":"Villanova University"},{"name":"Universidade Federal de Minas Gerais"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Glaucilene","family":"da Silva Costa","sequence":"additional","affiliation":[{"name":"Laborat\u00f3rio Central de Sa\u00fade P\u00fablica do Estado de Rond\u00f4nia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ana Cl\u00e1udia","family":"Calchi","sequence":"additional","affiliation":[{"name":"Faculdade de Ci\u00eancias Agr\u00e1rias e Veterin\u00e1rias, Universidade Estadual Paulista (FCAV\/UNESP)"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marcos Rog\u00e9rio","family":"Andr\u00e9","sequence":"additional","affiliation":[{"name":"Faculdade de Ci\u00eancias Agr\u00e1rias e Veterin\u00e1rias, Universidade Estadual Paulista (FCAV\/UNESP)"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0932-0479","authenticated-orcid":false,"given":"Lucio Andr\u00e9","family":"Viana","sequence":"additional","affiliation":[{"name":"Universidade Federal do Amap\u00e1"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Felipe Arley","family":"Costa Pessoa","sequence":"additional","affiliation":[{"name":"Instituto Oswaldo Cruz, IOC\/Fiocruz"},{"name":"Instituto Le\u00f4nidas e Maria Deane, Fiocruz Amaz\u00f4nia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"56","published-online":{"date-parts":[[2025,12,12]]},"container-title":["Parasitology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.cambridge.org\/core\/services\/aop-cambridge-core\/content\/view\/S0031182025101388","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,1,9]],"date-time":"2026-01-09T08:45:37Z","timestamp":1767948337000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.cambridge.org\/core\/product\/identifier\/S0031182025101388\/type\/journal_article"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,12,12]]},"references-count":0,"alternative-id":["S0031182025101388"],"URL":"https:\/\/doi.org\/10.1017\/s0031182025101388","relation":{},"ISSN":["0031-1820","1469-8161"],"issn-type":[{"value":"0031-1820","type":"print"},{"value":"1469-8161","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,12,12]]},"assertion":[{"value":"\u00a9 The Author(s), 2025.
