| description |
The members of the genus <i>Leucochloridium</i> (Trematoda, Leucochloridiidae) are cosmopolitan parasites from both the cloaca and bursa of Fabricius of birds, mainly Passeriformes. In South America three species of this genus have been reported: <i>Leucochloridium (Neoleucochloridium) flavum</i> Travassos, 1922 from Brazil and Venezuela, <i>L. (Leucochloridium) parcum</i> Travassos, 1922 and <i>L. (Papilloleucochloridium) pulchrum</i> Fernandes, 1970 from Brazil. No molecular data from leucochloridiids in the Southern hemisphere have been published so far. The aim of this work is to increase the knowledge of the helminth diversity of <i>Jacana jacana</i> in Argentina with a combined morphological and molecular approach. Two specimens of <i>J. jacana</i> were captured in Formosa province, Argentina, and nine digeneans were recovered from the cloaca of one of them. DNA was extracted and the barcode region of cytochrome c oxidase 1 (CO1) was sequenced for two specimens. Digeneans were identified as <i>L. (P.) pulchrum</i> through morphological study. These specimens differed from the original description of <i>L. (P.) pulchrum</i> by the smaller size of testes and the presence of minute spines in the anterior region of the tegument. The most similar CO1 sequences on GenBank are those of <i>Urogonimus macrostomus</i> (Leucochloridiidae) from <i>Passer domesticus</i> in western Canada which differed by a 21% from <i>L. (P.) pulchrum</i>. Our study expands the geographic range of Neotropical <i>Leucochloridium</i> species with both morphological and molecular data that will be useful for future works on regional diversity and life cycles. This finding constitutes the second report of this species since its original description, and the first record of the genus <i>Leucochloridium</i> for Argentina. |

Los miembros del género <i>Leucochloridium</i> (Trematoda, Leucochloridiidae) son parásitos cosmopolitas de la cloaca y bolsa de Fabricio de aves, principalmente Paseriformes. En Sudamérica se han reportado tres especies de este género: <i>Leucochloridium (Neoleucochloridium) flavum</i> Travassos, 1922 en Brasil y Venezuela, <i>L. (Leucochloridium) parcum</i> Travassos, 1922 y <i>L. (Papilloleucochloridium) pulchrum</i> Fernandes, 1970 en Brasil. Hasta el momento, no se han realizado trabajos con enfoques moleculares sobre los leucoclorididos en el hemisferio sur. El objetivo de este trabajo es ampliar el conocimiento de la diversidad de los helmintos de <i>Jacana jacana</i>, con nuevos datos morfológicos, geográficos y moleculares de <i>L. (P.) pulchrum</i>. Dos especímenes de <i>J. jacana</i> fueron capturados en la provincia de Formosa, Argentina, disecados en el campo y nueve digeneos fueron recuperados de la cloaca de uno de ellos. En dos digeneos se extrajo ADN y se generó la secuencia de código de barras de citocromo c oxidasa 1 (CO1). Los digeneos se identificaron como <i>L. (P.) pulchrum</i> por sus caracteres morfológicos. A diferencia de la descripción original, estos especímenes tienen testículos más pequeños y tegumento con pequeñas espinas en la región anterior. Las secuencias más similares de CO1 en GenBank son las de <i>Urogonimus macrostomus</i> (Leucochloridiidae) de <i>Passer domesticus</i> en el oeste de Canadá, que difieren en un 21% de <i>L. (P.) pulchrum</i>. Estos datos amplían el rango geográfico de especies neotropicales de <i>Leucochloridium</i> y serán útiles para futuros trabajos sobre diversidad regional y ciclos de vida. Este hallazgo constituye el segundo registro de la especie desde su descripción original y el primer registro del género <i>Leucochloridium</i> para Argentina.
