J. Parasitol. Parasites Wildl. 8 (2019) 203 e215. https://doi.org/10.1016/j.ijppaw.2019.02.005. This article
describes the communities of monogenean parasites in 11 populations of a small characid freshwater fish Astyanax aeneus
(Günther) separated by small geographical distances along
60 km of the Lacantún river in Chiapas, Mexico. We examined 15
A. aeneus from each of 11 locations (one sample in February, a
second sample in August 2012), situated at the mouth of the
streams opening into the main body of the Lacantún river, at the Montes Azules Biosphere Reserve in the Lacandon forest, Chiapas in southern Mexico. The area of study is located ~800 km from the mouth of the Usumacinta river in the Gulf of Mexico. In this paper we provide the data for 12 monogenean taxa. The materia
