Herein, we present the first Mexican record of Morelet’s crocodile, Crocodylus moreletii, as a host for the proboscis-bearing leech, Haementeria acuecueyetzin. From November 2004 to October 2017, we captured 111 crocodiles during spotlight surveys in lagoons of the Dziuché ejido, municipality of José María Morelos, Quintana Roo, Mexico. Twenty-one (18.9%) individuals had leeches identified as H. acuecueyetzin. It is the first report of H. acuecueyetzin for the State of Quintana Roo, Mexico, and the northernmost record of the species. This is also the second case of leech parasitism in C. moreletii. Haementeria acuecueyetzin likely parasitize a large array of vertebrates, and its role as apotential vector of blood parasites in C. moreletii requires further investigation.

Resumen en inglés

The genus Linguatula (Pentastomida) is cosmopolitan and includes 6 species that have a higher prevalence in subtropical, tropical, and temperate regions. Larvae (nymphs) of Linguatula spp. require an intermediate host (herbivorous), while the adult worms inhabit the respiratory tract of wild and domestic carnivores. During an ongoing project on conservation biology of Baird’s tapir (Tapirus bairdii), 3 pentastome nymphs were found parasitizing the liver, mesentery, and small intestine of an adult male from the region of Calakmul, Campeche, Mexico. Based on morphological and molecular data, these specimens correspond to Linguatula recurvata. Here, we present the first record of a linguatulid parasitizing a Tapirus sp., and only the second of a pentastomid in tapirs. In addition, this work includes for the first time sequences of the mitochondrial cytochrome c oxidase subunit I of L. recurvata.

A new genus and species of nematode, Tziminema unachi n. gen., n. sp. is described from the caecum and colon of Baird ’ s tapir Tapirus bairdii (Gill, 1865), found dead in the Reserva de la Biósfera El Triunfo, Chiapas State, in the Neotropical realm of Mexico. Tziminema n. gen. differs from the other nine genera included in the Strongylinae by two main characteristics: having 7 – 9 posteriorly directed tooth-like structures at the anterior end of the buccal capsule, and the external surface of the buccal capsule being heavily striated. Phylogenetic analyses of the DNA sequences of the mitochondrial cytochrome c oxidase and nuclear DNA, including a partial sequence of the internal transcribed spacer 1, 5.8S and a partial sequence of the internal transcribed spacer 2 of the new taxon, confirmed its inclusion in Strongylinae and its rank as a new genus.

Resumen en inglés

Invertebrate-derived ingested DNA (iDNA) is quickly proving to be a valuable, non-invasive tool for monitoring vertebrate species of conservation concern. Using the DNA barcoding locus, we successfully identified both the blood-feeding leech Haementeria acuecueyetzin and its blood meal-the latter is shown to be derived from the Caribbean manatee, Trichechus manatus . DNA amplification was successful despite the fact that the specimen was fixed in Mezcal (a beverage distilled from agave). We report the first confirmed case of a leech feeding on a manatee, the first record of H. acuecueyetzin for the State of Chiapas and, to our knowledge, the first case of successful DNA amplification of a biological sample fixed in Mezcal other than the caterpillar "worms" more commonly found in that beverage.
