“…represents the seventh species described of the genus Dollfusentis , which contains D. chandleri , D. bravoae , D. salgadoi , D. ctenorhynchus (Cable & Linderoth, 1963) Golvan, 1969, D. longispinus (Cable & Linderoth, 1963) Golvan, 1969, and D. lenti Keidel, García-Varela, Brener, Pérez-Ponce de León & Santos, 2019 associated mainly with brackish and marine fishes in the Americas (see Keidel et al . 2019). The new species can be differentiated from the other six congenerics species by the number of hooks in the proboscis.…”

“…sp., representing the fourth species recorded in coasts of the Gulf of Mexico and Caribbean Sea, and the seventh in the genus Dollfusentis , which is solely distributed across the Atlantic coast of the Americas in association to brackish water and marine fishes (see Keidel et al . 2019). The new species can be morphologically differentiated from the other congeneric species described by the number of longitudinal rows of hooks in the proboscis.…”

Acanthocephalans are a group of obligate endoparasites that alternate between vertebrates and invertebrates to complete their life cycles. Occasionally, the same individual host acts as a definitive or paratenic host for different acanthocephalan species. In this study, acanthocephalans were sampled in marine fish in three localities of the Yucatán Peninsula; adults and cystacanths were recovered from the intestine and body cavity, respectively, of Haemulon plumierii from off the coast of Sisal, Yucatán. Ribosomal DNA sequences (small and large subunits) were used to test the phylogenetic position of the species of the genus Dollfusentis, whereas the mtDNA gene cox 1 was used for assessing species delimitation. The cox 1 analysis revealed an independent genetic lineage, which is recognized herein as a new species, Dollfusentis mayae n. sp. The new species is morphologically distinguished from the other six congeners by having a cylindrical proboscis armed with 22–25 longitudinal rows bearing 12 hooks each. The cystacanths were morphologically identified as Gorgorhynchus medius by having a cylindrical trunk covered with tiny irregular spines on the anterior region, and a cylindrical proboscis armed with 17–18 longitudinal rows of 21 hooks each; small and large subunit phylogenetic analyses yielded G. medius within the family Isthomosacanthidae, suggesting that Gorgorhynchus should be transferred to this family from Rhadinorhynchidae where it is currently allocated.

“…[130]). Whereas 28S and ITS provided a good phylogenetic signal that enabled reliable delimitation of species and genera from diverse families of acanthocephalans [86,145], the mitochondrial COI gene has been used to successfully define, recognize, delineate, and better understand intraspecific variation among the acanthocephalans [3,101,127,131,145,176]. The 18S has been proven informative for taxonomic and phylogenetic studies on acanthocephalans, often in association with 28S, ITS and/or COI (more than 80 references).…”

Although interest in Acanthocephala seems to have reached only a small community of researchers worldwide, we show in this opinion article that this group of parasites is composed of excellent model organisms for studying key questions in parasite molecular biology and cytogenetics, evolutionary ecology, and ecotoxicology. Their shared ancestry with free-living rotifers makes them an ideal group to explore the origins of the parasitic lifestyle and evolutionary drivers of host shifts and environmental transitions. They also provide useful features in the quest to decipher the proximate mechanisms of parasite-induced phenotypic alterations and better understand the evolution of behavioral manipulation. From an applied perspective, acanthocephalans’ ability to accumulate contaminants offers useful opportunities to monitor the impacts – and evaluate the possible mitigation – of anthropogenic pollutants on aquatic fauna and develop the environmental parasitology framework. However, exploring these exciting research avenues will require connecting fragmentary knowledge by enlarging the taxonomic coverage of molecular and phenotypic data. In this opinion paper, we highlight the needs and opportunities of research on Acanthocephala in three main directions: (i) integrative taxonomy (including non-molecular tools) and phylogeny-based comparative analysis; (ii) ecology and evolution of life cycles, transmission strategies and host ranges; and (iii) environmental issues related to global changes, including ecotoxicology. In each section, the most promising ideas and developments are presented based on selected case studies, with the goal that the present and future generations of parasitologists further explore and increase knowledge of Acanthocephala.
