The present study analyzed the morphology and morphometry of P. bragai. Adult specimens of the parasite were collected from naturally infected Columba livia kidneys, fixed and prepared for observation via bright field and differential interference contrast light microscopy and scanning electron microscopy. The parasite has an elongated and flattened body, with a subterminal oral sucker located at the anterior end of the body, as observed by all techniques used. Staining the parasite with hematoxylin-eosin enabled observation of the pharynx, located posteriorly to the oral sucker, the vitelline glands, which are extra-cecal and extend anteriorly to the pre-ovarian region and later to the median region of the body, and intestinal caeca parallel to the vitelline glands. The presence and functionality of the acetabulum are controversial points in the literature, but it was observed in all specimens analyzed by scanning electron microscopy, with a major diameter of 38.36 \u00b1 6.96 (28.77 \u2013 45.39) and minor diameter of 31.59 \u00b1 7.04 (21.75 - 38.16). Close to the acetabulum, scales were observed in the integument of the parasite. Scales with (1 - 5) blade divisions were identified. In the genital pore, it was possible to see the everted cirrus with rosette shape. The excretory pore (first morphometric record) is dorsal and subterminal, with major diameter of 12.27 \u00b1 9.16 (5.79 - 18.75) and minor diameter of 3.95 \u00b1 1.49 (2.89 - 5.00).<\/jats:p>","DOI":"10.1590\/1519-6984.271401","type":"journal-article","created":{"date-parts":[[2023,5,26]],"date-time":"2023-05-26T12:02:51Z","timestamp":1685102571000},"source":"Crossref","is-referenced-by-count":0,"title":["Morphology and morphometry of Paratanaisia bragai () Freitas, 1959 (Digenea, Eucotylidae) through light and scanning electron microscopy"],"prefix":"10.1590","volume":"83","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4706-1092","authenticated-orcid":false,"given":"V.
