These two new records were based on four specimens, three males and one female, collected in February 2019, which were identified as Betta picta since the males possess the main diagnostic features of the species: opercle with yellow-gold iridescence coloration, interrupted stripe below eyes, and a dark subdistal band on caudal and anal fins. Currently, this species is categorized as Near Threatened (NT) by the IUCN, and considering the negative effects of urbanization over the species natural habitats, the new records are important for the species conservation.</p> Felipe Ottoni Veryl Hasan Dian Samitra Endang Dewi Masithah Maheno Sri Widodo Susilo Irwanjasmoro Lucas de Oliveira Vieira Copyright (c) 2023 Boletim do Laboratório de Hidrobiologia http://creativecommons.org/licenses/by/4.0 2023-08-18 2023-08-18 32 2 10.18764/1981-6421e2022.5 http://periodicoseletronicos.ufma.br/index.php/blabohidro/article/view/20866 <p>In this paper, the first record of Tuxophorus caligodes Wilson, 1908 (Siphonostomatoida: Caligidae) off the North coast of Brazil is documented.
